1.1 Selected topic and background
Since the 21st century, with the rapid development of Internet technology, the Internet has spread all over the world, and smart phones have become an indispensable part of people's daily life. Online shopping apps have opened up a new consumption experience for people, and the express service industry has also emerged. As an emerging industry in my country, the express delivery industry has developed rapidly under the impetus of network technology. Now large private enterprises such as SF Express, Yunda, Yuantong, and Shentong have emerged. Some small private enterprises are also sprouting and developing. Today, the supply of express delivery services exceeds demand. The competition among enterprises is also deteriorating day by day, and the social harms brought about by vicious competition are becoming more and more prominent, such as stealing express mails and fastenings and other bad behaviors. On the other hand, private express delivery companies do not have high requirements for the quality of employees, and professional training is also so-so, which has led to a significant reduction in the quality of corporate services. Secondly, there are still a large number of express delivery sites that adopt the traditional manual management method. Once the express delivery peak period or a large number of express deliveries are piled up, it is very easy to cause problems such as loss of express delivery. Human-machine statistical re-summarization is currently a relatively advanced express site management method. This method still has many shortcomings, such as data redundancy, lack of timeliness, etc. Constraints. In addition, the excessive and vicious competition within the industry, the constraints of relevant laws and regulations, and the increase in labor costs all hinder the development of the express delivery industry.
1.2 Research status at home and abroad
The scale of express delivery companies in my country: Compared with other industries, the technical requirements of the express delivery industry are relatively low, and the cost is relatively low. Therefore, over the years, large and small express delivery private companies have emerged, but the real strength is China Post and others. Among the large state-owned enterprises and a small number of private enterprises, China Post Express Company has the largest scale and the largest number of branches, distributed in more than 200 countries and regions, and more than 200 mail processing centers have been established in China. SF Express, STO Express, and Yunda are representatives of large private enterprises. For example, SF Express, from its initial establishment in 1993 to 2010, has successively established thousands of business outlets in Hong Kong, Taiwan and other parts of the country, as well as South Korea and Singapore, and is still developing vigorously today. The shortcomings of my country's express delivery companies: (1) Market chaos: Due to the relatively low entry barriers to the express delivery industry, countless express delivery companies with varying scales and management levels have been established. Due to the large number of companies, the supply of express delivery markets exceeds In recent years, vicious competition between enterprises has been intensified, such as price wars between enterprises and bad behaviors such as stealing and fastening that often occur within enterprises, which have seriously affected the development of my country's express delivery industry. (2) Low service quality Because the courier job does not require a lot of professional skills, normal ordinary people can be engaged in the courier profession, which relieves the pressure on the labor market to a certain extent, but on the other hand leads to express delivery The professional level of employees has been reduced, the service attitude is not as good as before, and customer complaints are also increasing, which greatly reduces the reputation of express companies and also restricts the development of the express industry. (3) Poor emergency response capability: The express delivery system is often paralyzed due to external factors such as weather and festivals, such as the accumulation of express deliveries caused by snowstorms and the increase in the number of deliveries caused by shopping festivals such as Double Eleven. Due to the backward management system of express delivery companies, Thereby can't deal with emergencies in a timely and effective manner. In addition to the above reasons, a series of factors such as high fuel prices, rising labor costs and the introduction of foreign express delivery companies are restricting the progress and development of my country's express delivery industry.
All aspects of the American logistics industry have been at the forefront of the world for many years. From the 20th century to the present, it has experienced four stages of rapid development from budding to promotion to modernization and to today's information globalization. It adopts an integrated management method and puts the overall interests in the forefront. In the center, the traditional method of branch management is abandoned, and the entire enterprise is managed in a unified manner. In terms of the government's management of the enterprise, there is no specific management department, and regional management is still adopted. Each link of express delivery is managed according to the specific functions of the department. The government At the same time, a series of laws and regulations that are conducive to the development of the logistics industry have been formulated, and the company has also developed advanced identification technology and management systems to improve the operating efficiency of the company.
The development of the European logistics industry has gone through five stages from the 1950s to the present: (1) factory logistics stage (2) integrated logistics stage (3) supply chain logistics stage (4) global logistics stage (5) electronic logistics stage . At present, the scale of European express delivery companies is also increasing, and the use of modern technology and professional service models in enterprise management is also increasingly prominent. Most enterprises pay more attention to the mastery of core technology and the improvement of market regulation ability, and manage other aspects through the rational use of external resources.

2.1 Myeclipse Description
The software we usually use when we use Java to develop the system is Myeclipse, which is used to design the collection of Eclipse plug-ins for Java and JavaEE. Most of Myeclipse can realize the research and development of Mysql database and Javaee. Using Myeclipse greatly facilitates developers, and the progress of system development will also be improved.
2. 2 Mysql description
Now the Mysql database can support many users on the network, and it can also adapt to the deployment or configuration of customer service machines and servers. Our server and client machines here are actually a software concept, and the computer hardware we use is also There is no one-to-one correspondence with them.
Mysql is a very popular relational database management system, and its appearance has always been a leader. It is not only very powerful, but also very convenient to use, and Mysql's cross-platform ability is also very good, software developers like it very much of these powerful advantages. Different from other relational databases, it has its own set of solutions for database management, and manages the database by setting corresponding permissions and roles for users. It can be seen that Mysql is a database management software suitable for high throughput, high reliability and high efficiency.
Advantage 1: Mysql sets different permissions for users with different identities to complete different business logics, which makes Mysql far exceed other relational databases in terms of security and integrity.
Advantage 2: Mysql can also support the data types of animation, graphics and sound, which means that multiple data types can also be supported by Mysql.
Advantage 3: Mysql can also be developed on multiple platforms, and various programming languages for software development can realize the operation of Mysql database.
2. 3 Tomcat Description
Tomcat is a free server. The usage scenario is more suitable for situations where the number of visits is relatively small. It means that when Tomcat is installed on the computer, the access request of the front-end HTML page can be parsed through it. In fact, Tomcat is an extension of Apache, but it works relatively independently of Apache, so it can be seen that it runs relatively independently of Apache.
Tomcat was originally developed and applied by Davidson of Sun Company. After his efforts, he has continuously turned it into an open source server. It was also handed over to the Apache Software Foundation by the sun company. The ever-evolving tomcat server has undergone a lot of refactoring and combing in a recent version to make it more convenient to use. The Tomcat-based load balancing algorithm is an open source software implementation. There is no need to add additional hardware investment, and it is very convenient to implement, especially suitable for the expansion of general small business website servers at present and in the future. Judging from the current practice, it can be used as a reference for similar applications.
2.4 Introduction to spring boot framework
The Spring framework is an open source application framework on the Java platform that provides a container with inversion of control features. Although the Spring framework itself has no restrictions on the programming model, its frequent use in Java applications made it so popular that it was later used as a supplement or even a substitute for the EJB (EnterpriseJavaBeans) model. The Spring framework provides a series of solutions for development, such as using the core features of inversion of control, and implementing inversion of control through dependency injection to realize the containerization of the management object life cycle, using aspect-oriented programming for declarative transaction management, and integrating A variety of persistence technologies manage data access, provide a large number of excellent web frameworks to facilitate development, and so on. The Spring framework has the feature of inversion of control (IOC). IOC is designed to facilitate project maintenance and testing. It provides a method for unified configuration and management of Java objects through the Java reflection mechanism. The Spring framework uses the container to manage the life cycle of objects. The container can configure objects by scanning XML files or specific Java annotations on classes. Developers can obtain objects through dependency lookup or dependency injection. Aspect Oriented Programming(AOP) framework, the Spring AOP framework is based on the proxy mode, and can be configured at runtime; the AOP framework is mainly modularized for the cross concerns between modules. The AOP framework of the Spring framework only provides basic AOP features. Although it cannot be compared with the AspectJ framework, it can also meet the basic needs through integration with AspectJ. Functions such as transaction management and remote access under the Spring framework can be realized by using Spring AOP technology. Spring's transaction management framework brings an abstraction mechanism to the Java platform that enables local and global transactions, as well as nested transactions, to work with savepoints and in almost any environment on the Java platform. Spring integrates multiple transaction templates. The system can configure transactions through transaction templates, XML or Java annotations, and the transaction framework integrates functions such as messaging and caching. Spring's data access framework addresses common difficulties developers encounter when using databases in their applications. It not only provides support for all popular data access frameworks such as Java: JDBC, iBATS/MyBATIs, Hibernate, Java Data Objects (JDO), ApacheOJB and Apache Cayne, but also can be used with Spring's transaction management to provide data access Flexible abstraction. The Spring framework initially did not intend to build its own Web MVC framework . During the development process, its developers believed that the separation between the presentation layer and the request processing layer of the existing Struts Web framework and between the request processing layer and the model was not enough, so they created Spring MVC.
3.1 Demand Analysis
Before any project is developed and researched, it is necessary to make a careful analysis of the needs of the R&D system itself. Market research cannot be ignored. Determine the functional requirements of the users from the actual scene, so as to clarify the goals and develop the entire system. There is a more accurate positioning. In this chapter, it is necessary to analyze the performance of the system, the business process, and the data. The overall interface of the community express delivery service system is simple and the functions are complete.
The feasibility of requirements is to analyze and discuss what kind of requirements the developed system can meet. Whether the developed system platform meets the previous requirements. Only in the development of a pre-assessment system can the requirements be completed prior to system development and implementation. If it is not feasible for you to develop a system that does not function properly, then it is development failure. Whether the development system is useful or not can fulfill the requirements discussed before. The following analyzes the actual needs of the community express delivery service system.
System design needs to start with the actual needs of users and administrators to understand what functions they need to implement and what administrative work they can include.
Considering the design characteristics of the community courier pick-up service system, several requirements should be met:
(1) It can carry out the management of the community express delivery service system through the network, and promote the information management of the community express delivery service system.
(2) Learning methods become more diverse and management is more standardized;
(3) It provides a free channel to ensure real-time and effective communication of data.
3.2 Feasibility analysis
This design is based on the B/S mode, and the Java technology is used to implement the MySQL database and Myeclipse. The overall feasibility is divided into the following three aspects.
3.2.1 Technical Feasibility Analysis
The so-called technical feasibility refers to whether the functions planned in the early stage can be satisfied within a limited time. Whether there will be problems that cannot be solved in the development and design. Whether the completed project can be well applied, if there are shortcomings, whether there is great difficulty in later maintenance. After evaluating the system, it was determined that existing technology could achieve the goals. Using Java technology to realize dynamic pages, embedding low-dependency design patterns, flexible databases, and stable servers, the operating efficiency of the entire system is greatly improved. It can be seen that achieving the goal at the technical level is not a nonsense.
3.2.2 Economic Feasibility Analysis
Most of the tools used in the project are currently popular open source and free, so in the early stage of development, the funds used for the project will be greatly reduced, and the development of the software will not be affected by the funds during the project start-up period, so It is still economically feasible. Try to use the least cost to meet the needs of users. Save funds for labor costs and equipment costs. It will go further and further on the road of paperless and high efficiency.
3.2.3 Operation Feasibility Analysis
The operation of this system to realize the functions is very simple. The common configuration of ordinary mobile phones can run this software, and as long as you have a rough understanding of the basic common sense of computer use, you can use this software smoothly. The mobile phone has the ability to connect to the Internet and can access the system normally. It does not require the operator to have any superb ability. It only needs to understand the business process and operate correctly according to professional knowledge. Therefore, the community express delivery service system is operational and feasible. sex.
3.3 Performance Analysis
For performance analysis, compared with the traditional management method, the traditional management method uses manual statistics and management of data information with paper and pen, and this method is more troublesome for storing and finding certain data information. With the advent of computer networks, this traditional method is difficult to adapt to the development of the current society. It not only reduces people's work efficiency, but also requires a lot of manpower and material resources, which is relatively high in terms of time and cost. Reduce costs, improve user efficiency, and develop a set of community express delivery service systems based on computer and network technology.
The development and design of the community express delivery service system is an independent system, and the data storage and development are carried out with the previous database, mainly to realize the user roles and corresponding functional modules of the community express delivery service system, so that the community express delivery service The management of the system will not have management differences and low efficiency, but is just the opposite of traditional management information. The realization of the community express delivery service system can save resources, and the processing speed of business is also improved, fast, efficient, and functional powerful.
3.4 System operation process
3.4.1 User login process
The first hurdle for system security is that users who want to enter the system must enter their own login information through the login window before they can log in. Only after the information entered by the user is accurate can they enter the operating system interface and perform function modules. The corresponding operation, if the information entered by the user is incorrect, a prompt box will appear in the window, and the user fails to log in. Return to the first step to re-enter, as shown in Figure 3-1.
Figure 3-1 User use case diagram
3.4.2 Information adding process
For the community express pick-up service system, you need to add the required community express pick-up service system work data information at any time. For users to add information, you need to fill in the community express pick-up service system to be added according to the content of the check box on the adding interface. Work data information. After the information input is completed, judge whether the data information meets the requirements. If the information meets the requirements, the addition is completed. If the information added by the user does not meet the requirements, you need to return to the first step, re-enter the data information, and then perform the judgment operation, as shown in the figure 3-2 shown.
Figure 3-2 Information adding flow chart
3.4.3 Information deletion process
No matter which user role enters the unreasonable system operation interface, it can perform different information content operation functions. For the deletion of system data information, once the user deletes the information, the deleted data information will not be restored. Therefore, the user When deleting data, it is necessary to judge whether the content to be deleted is determined to be deleted. After confirming that it is correct, choose to confirm the deletion operation, as shown in Figure 3-3.
Figure 3-3 Information deletion flow chart
4.1 System architecture design
An overview design analysis of the system project of the community express delivery service system, the main content is the specific analysis of the community express delivery service system, the database is designed, the data uses the mysql database, and the design of the system adopts a more humanized operation design , for the error information of the system, it can be processed and fed back in time.
The design of the community-based courier replacement service system is based on existing computers, which can realize administrators, homepage, site management (bulletin boards, carousel maps), user management (administrators), content management (articles, article types) and more management ( Apply for detailed understanding and statistical analysis of courier, courier, ordinary user, courier pick-up, excellent courier, courier status, area management, etc. The module relationship diagram established according to the system functional requirements is as follows:
Figure 4-1 Administrator function module diagram
The design of the community-based courier replacement service system is based on existing computers, which can realize detailed understanding and statistical analysis of users, home pages, bulletin boards, life information, application for couriers, excellent couriers, and mine. The module relationship diagram established according to the system functional requirements is as follows:
Figure 4-2 User function module diagram
4.2 Development process design
The development of the community courier service system analyzes the management module and the database used by the system, writes the development, planning and operation are the necessary three steps to build the information management application program, which determines whether the system can really realize the preset functions and Can it be implemented after successful design. In the development process, each stage must be developed in strict accordance with the linear sequence, and each work generated in the corresponding stage can be verified and checked by technology. Make sure that it is correct after the completion of one stage, and will not cause drag and drop phenomenon in the next stage, so that the system can be guaranteed after the design function is completed.
Judging from the successful development experience of the community express delivery service system, the above method has the most obvious effect and minimizes the complexity of system development. As shown in Figure 4-2.
Figure 4-2 Flow chart of the development system
4.3 Database design
Database is the foundation and core of information system. The quality of database design directly affects the success or failure of information system development. Creating a database table first determines the attributes of entities and the relationships between entities. Create a data table based on the relationship.
4.3.1 Entity ER Diagram
The database is the most important step in the entire software programming. For the database problem, it is mainly to determine the number of databases and the creation of structural formulas. The display system uses Mysql to manage the database to ensure data security and stability.
Conceptual models are designed to abstract real-world information and model the information world. It is a powerful tool for database design. Database conceptual model design can describe the conceptual model of the real world through ER diagrams. An ER diagram of a system shows the links between entities in the system. Moreover, the Mysql database is a database with relatively strong self-protection capabilities. The following figure is mainly an ER diagram of database entities:
(1) The ER diagram of express delivery information management, as shown in Figure 4-3:
Figure 4-3 Entity attribute map of express delivery information
(2) The ER diagram of express status management is shown in Figure 4-4:
Figure 4-4 Express status management entity diagram
These functions can fully meet the needs of the community courier pick-up service system. The function of this system is relatively comprehensive, as shown in Figure 4-5 below the system function structure.
Figure 4-5 System function structure diagram
4.3.2 Data Sheet
According to the detailed analysis requirements of the data structure, we can analyze according to the requirements of the input and output data volume, determine what table, the relationship between the structure, we can verify, adjust and improve, query and browse the process, can realize the database, In order to make users have more requirements for data and functions.
Based on the characteristics of the database management system used by the system, the conceptual model of the database is converted and constructed. However, this system only needs to fully consider the functions of the community express delivery service system, and the organization is relatively clear.

6.3测试结果
经过对此系统的测试，得出该系统足以满足用户日常需求，在功能项目和操作等方面也能满足操作员对于其他用户的管理。但是，还有很多功能有待添加，这个系统仅能满足大部分的需求，还需要对此系统的功能更进一步的完善，这样使用起来才能更加的完美。
第7章 总结与展望
通过社区快递代取服务系统的开发，本人巩固了之前学过的知识，如今将平时所学到的知识融合在设计中，在设计过程中，做了很多的准备，首先，在数据库系统的设计过程中，尤其是在数据库的工作原理、工作特点，对其深刻的讨论，与此同时，对于小型站点来说，最好服务器的选择，其次，利用所学的知识点分析所做的系统，并在此基础上设计。
目前本系统已经上线，正在试运行阶段，用户反馈良好，基本完成用户所需，试运行过程中没有出现阻断性问题，有一些不足和小问题也及时予以修正，系统上线后，为了保证数据的安全性，对系统进行了备份操作，系统备份是每两个月备份一次，数据库备份为每周备份一次，系统部署在社区快递代取服务系统的云平台服务器中。
本次系统上线成功后，得到了用户的高度认可，但是在功能上和性能上还需做进一步的研究处理，使其有更高的性能和更好的用户体验。
系统在以后的升级过程中，需要解决一系列用户所提出的问题，例如打印过程中如何避免浏览器的兼容性问题，大量用户访问时，如何保持较高的响应速度，在系统今后的升级过程中将着重解决这些安全性问题。
