1 Overview
1.1 Research background
System management will also be carried out through computers for overall intelligent operation. The agricultural product promotion system involves a lot of management and data storage, such as administrator; home page, site management (carousel chart, bulletin board) user management (management Members, system users) content management (community sharing, sharing categories) mall management (product information, category list, order list) , users; homepage, orders, shopping cart, community sharing, mine (basic information, delivery address, collection , orders, shopping carts), etc., which brings huge challenges to the work of managers. In the face of a large amount of information, traditional management systems all collect statistics of detailed information through notes. Later, computers appeared, and through computers Input software counts paper information to the computer. This method is relatively traditional, and it is troublesome to collect statistical information. It is also affected by time and space. Therefore, an agricultural product promotion system was developed for this purpose ; it provides users with convenient management. The platform is convenient for administrators to view and maintain, and can edit and maintain content according to requirements; for users , they can query the required information at any time , and administrators can obtain system data information, etc. without leaving home. , and it can also save users a lot of time, so the development of agricultural product promotion system brings great convenience to managers, and it also facilitates administrators to process user information.
This paper's agricultural product promotion system mainly involves programs, databases and computer technology. Covering a wide range of knowledge can greatly improve the work efficiency of system personnel .
1.2 Research significance
With the continuous development of the domestic economic situation, China's Internet has entered a rare period of peak development, which has caused Chinese and foreign capitalists to turn to the Internet market. However, the unreasonable structure, shortage of personnel and the increase in market management needs in many management fields have made more people aware of Internet management.
In today's highly developed information, information management reform has become a more extensive and comprehensive trend. The " agricultural product promotion system " is based on Mysql database and implemented on the basis of springboot framework programming. In order to ensure the sustainable development of China's economy, the information age is increasingly updated, and the service industry is still booming . At the same time, with the rapid development of the information society, various management systems are faced with more and more data that need to be processed. How to enable managers to query, store, manage and share effective data in the vast data ocean in a convenient and fast way? Information has important practical significance for our study, work and life. Therefore, academic circles at home and abroad have conducted in-depth and extensive research on this, and a new research field- agricultural product promotion system was born.
1.3 Main work of this topic
At the beginning, this article gives an overall description of the basic knowledge discussed in the system, and conducts a system analysis on this basis. In order to enable this system to be designed and implemented in a better and more complete manner, analysis and investigation must be conducted first. Based on the previous related foundations, a detailed analysis of the new system was carried out in terms of functionality. Then through detailed analysis, system design was carried out. Secondly, in terms of the feasibility of system implementation, I chose Android technology for development and design. For data storage, I used Mysql database for design. Since both Android and Mysql are very mature, they are very reliable, safe and practical in all aspects. Finally, the system is tested, perfected and released.
2 System development environment
2.1 java technology
The Java language was released by Sun at the end of the 20th century, and the source code was open. This advantage attracted many outstanding programming enthusiasts from all over the world, and also enabled them to develop classic and fun games one after another at that time. The Java language is one of the pure object-oriented languages. From the early days of its release to the present, it can be said that it has a history of nearly 20 years and has developed into a profound influence in the history of human computer programming language development.
The Java language has a variety of features: (1) Cross-platform independence; (2) Object-oriented; (3) Security is guaranteed; (4) Supports multiple tasks; (5) Multiple writing methods, code writing Simple. Compared with other low-level languages and high-level languages, the Java language has obvious advantages and broad prospects in the future. It can be widely used in personal laptops, big data, large-scale games, etc.
First of all, the Java language has object-oriented characteristics and is easy to understand. Regarding objects, it can actually be understood that every thing is an object, including us humans. Utilize the basic characteristics of object-oriented languages to solve practical problems in software development and provide technical support for effective software development.
Secondly, the Java language has good cross-platform independence. The application program written is written in Java language, so there is no need to use a compiler to modify the program code, and it can be run directly on any computer system, including Windows systems and Linux systems, that is, after one compilation , can run everywhere, so the Java language has excellent portability and can be implemented well across platforms.
2. 2 Mysql database
The mysql database has many advantages, such as its easy-to-understand operation, powerful functions, and high information storage capacity. Therefore, it is widely used by people. For mysql database, it is generally mainly used for encoding and querying data, and it is applied to this database in many designs. In this process, we can query and combine conventional data, so When we use the mysql database, we only need to write a small piece of data to achieve the corresponding function. A database is a storage room for data storage, but the data is stored on a computer instead of a real storage room. The data is stored in a fixed format, not disordered. The definition is: a fixed format for a long time. Storage on computer memory that can be shared. Database management mainly includes the establishment of data tables, data storage, modification and addition of data. In order to ensure that the database system can operate normally, the management work carried out by relevant personnel. The establishment of the data table can adjust the data in the data table, recombine and reconstruct the data to ensure the security of the data.
2.3 Android technology
Android is an operating system based on the Linux kernel. It was developed by Google in the early days and later by the Open Handset Alliance. It adopts a software heap architecture and is mainly divided into three parts. The bottom layer is based on the Linux kernel and only provides basic functions; other application software is developed by each company, using Java as part of the program. In addition, in order to promote this technology, Google and dozens of other mobile phone companies established the Open Mobile Alliance. Android was often rumored to be GPhone before it was made public.
It adopts a software stack (also known as software stack) architecture, which is mainly divided into three parts: the bottom layer is based on the Linux core, developed in C language, and only provides basic functions. The middle layer includes the function library Library and the virtual machine Virtual Machine, which is developed in C++. The top layer is various application software, including call programs, text message programs, etc. The application software is developed by each company and written in Java.
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 control inversion characteristics. 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 (Enterprise JavaBeans) model. The Spring framework provides a series of solutions for development, such as utilizing the core features of inversion of control and implementing inversion of control through dependency injection to implement containerization of the managed object life cycle, using aspect-oriented programming for declarative transaction management, and integration 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 Inversion of Control (IOC) feature. IOC is designed to facilitate project maintenance and testing. It provides a method for unified configuration and management of Java objects through Java's reflection mechanism. The Spring framework uses containers 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. The Spring framework has an aspect-oriented programming (AOP) framework. The Spring AOP framework is based on the proxy mode and is configurable at runtime; the AOP framework mainly modularizes 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 basic needs through integration with AspectJ. Transaction management, remote access and other functions 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 a variety of 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 solves 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 ApacheCayne, but can also be used with Spring's transaction management to provide data access. Flexible abstraction. The Spring framework did not initially 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 StrutsWeb framework, as well as between the request processing layer and the model, was not enough, so they created SpringMVC.
3 System analysis
The so-called system analysis is that the administrator obtains information through communication with the user client, and then displays this information to users and developers in the form of requirements specifications. In the long history of the development of software functions, for a long time, especially in the beginning, the importance of requirements analysis was not recognized by people. For example, at that time, the American company IBM developed an information management system for British Telecom. Development started without clarity, and the initial construction period was one year. Due to unclear requirements, the construction period was delayed by more than half a year, causing huge losses. This situation also exists in many of our software companies. They develop while developing, and even without clear communication with customers, directly copy the same type of projects and make changes. As a result, when the system is accepted, changes are made again, resulting in a loss of manpower and material resources. A huge waste. The reason for all these consequences is that the demand acquisition is not timely, unclear, and incomplete.
3.1 Feasibility analysis
The main goal of the agricultural product promotion system APP is to realize related information management services such as community sharing, product information, classification lists, and order lists. After determining the goals, we conduct a feasibility analysis on whether the goals of this system can be achieved from the following four aspects.

It uses a common interface window to log in to the interface and access the operation through a computer. Users can access the operation as long as they have used a computer in daily life. The development of this system uses Android development, and the background is combined with Java language. These development environments make the system more complete. This system has the characteristics of easy operation, easy management, good interactivity, and is very simple in operation. Therefore this system can be developed.
3.1.3 Economic feasibility
The agricultural product promotion system APP is based on the B/S model and Java technology on the server side. The client uses Android and Mysql database to store data. The required hardware and software environment are easy to purchase in the market. Program development is mainly the development of the management system. And maintenance. Therefore, the program does not require high development manpower and financial resources, and the system is not very complex, the development cycle is short, and it has high economic feasibility.
3.1.4 Legal feasibility
This agricultural product promotion system APP is a self-designed management system and has great practical significance. Because both the software and the database use open source code, the development and design of this system does not have problems such as infringement and is completely legally feasible.
In summary, the agricultural product promotion system APP is technically, economically, operationally and legally feasible, and it is feasible to develop this program.

4System Overview
After the system analysis, we begin to memorize system design. System design includes overall design and detailed design. The overall design is just a general design. After the overall design, we can divide some things of the system, such as files, documents, data, etc. And through the overall design, we can roughly divide the modules and functions of the program. But it is only a preliminary classification and has no real implementation.
The overall design is just a preliminary design. Moreover, for a project, we can carry out multiple overall designs. Through comparison, including performance comparison, cost comparison, and benefit comparison, we can finally determine an optimal design plan and choose the best one. The overall design can reduce development costs and increase company benefits. From this point of view, the overall design is still very important.
The working principle diagram of the agricultural product promotion system is shown in Figure 4-1:

4. 2 Database design
Database is the basis of computer information system. At present, the key and core part of the computer system is the database. The quality of database development has a direct impact on the quality and speed of the entire system.
4.2.1 Database design principles
The conceptual model is mainly based on the analysis of data requirements. It usually uses a conceptual data model to represent the relationship between various data, and processes and manages information for system users. At the same time, it establishes an ER diagram to represent specific Entities, attributes, and relationships.
4.2.2 Database entities
4. 3 Database design principles
The applications of each database are separated from each other. When running into a certain program, it will communicate with the client through its own related protocols. Then this system will connect these data. When we choose which segment, we will briefly describe how the database is created. When you click the Finish button, the name of the data source will automatically pop up in the dialog box. Just click Next and directly enter the corresponding authentication and login password.

6系统测试
系统开发的最后一个步骤就是系统测试，系统测试也是整个系统十分重要的一个环节，测试的好坏关系到产品的发展。客户对软件的质量、性能和可靠性等需求就要通过测试来实现。测试过程要必须遵循严谨性、完善性、规范性的原则，测试的主要目的就是看看在系统运行中，是否会出现bug，然后对出现的bug进行调试，直到程序完美运行。但是软件的测试只能尽可能的减少bug，理论上来说是无法达到消除bug。但是bug越少，系统出错的几率就越低，用户使用起来也更方便、更安全。
近年来，软件包含测试从现在的检验当中来看，系统接近预期目标可能出现的问题，并对这些错误做出相应的修正，假如我们不进行早期的测试错误就会延续下去，最后所做出的成品就会有很大的困难。
我们要在这个测试的过程当中找出错误。测试成软件开发的主要一部分，自从有了程序的设计那天开始，它就成为了重要的组成部分。经过统计来看，软件测试可以占据这个系统45%的工作量，而在软件开发的成本当中，对于测试成本来说它包含了很多的测试工作。每个程序测试时都会出现和遇到错误。在整个程序的开发过程当中，人为去查找错误是非常复杂和困难的，所以我们一般都会找一些测试的工具来进行测试
6.1系统测试的意义
随着现代信息的快速发展，在社会各大领域中已经都开始应用网络信息技术，在应用网络技术的同时人们也开始把软件的质量问题作为了一个重要焦点来关注，因为一个软件的好与坏它决定着这个系统在市场上的生存，所以我们必须要把软件质量来做好，这样才有一定的生存能力。对于用户来说它们首先选用的都是保证这个系统软件的质量问题，因为一个系统的软件质量决定着用户在后期上成本经济的问题。图6-1就是纠错测试流程。
图6-1 测试与纠错信息流程
6.2 测试方法
黑盒测试又被人们称作为功能测试，通常是在程序的接口来做一些测试的方法，它一般包括对程序的功能和使用的方法来做出一些数据的接受和输出，同时还可以做出正确的输出信息，并保证与外部信息的完整性。
白盒测试通常被人们称作为结构测试，在整个程序的结构和处理当中它是由程序当中的逻辑测试和检验程序来完成一些正确的工作。
具体的功能测试它是包括：系统的适用性、准确性、安全性等功能测试。
6.3测试分析
本农产品推广系统APP满足相关信息的管理需求，在设计时借鉴了国内外优秀网站的优点，从界面到系统设计都保证了管理员以及用户能够方便操作。系统的主要特点和优点归纳如下：
（1）本系统用的移置性和针对性都比较高，因为针对性高可以提供更好的服务而移置性可以在多个系统上运行，更给用户带来了极大的方便。
（2）该农产品推广系统APP内容全面，管理方便可以及时的全面的处理各种错误，异常，这样避免了很多因用户的马虎操作而出现的失误，其操作方便，用户界面友好，能够上网的人都可以很好的进行操作。
经过对上述的测试结果分析，所有基本功能齐全，操作简单，系统运行性能良好，系统安全可靠，能促进农产品推广系统的发展，发展前景广阔。
结 论
本系统通过对Android、java和Mysql数据库的简介，从硬件和软件两反面说明了农产品推广系统APP的可行性，本文结论及研究成果如下：实现了Android、java与Mysql相结合构建的农产品推广系统APP，网站可以响应式展示。通过本次农产品推广系统APP的研究与实现，我感到学海无涯，学习是没有终点的，而且实践出真知，只有多动手才能尽快掌握它，经验对系统的开发非常重要，经验不足，就难免会有许多考虑不周之处。比如要有美观的界面，更完善的功能，才能吸引更多的用户。
由于在此之前对于Java知识没有深入了解，所以从一开始就碰到许多困难，例如一开始的页面显示不规范、数据库连接有问题已经无法实现参数的传递等等，不过通过在网上寻找有关资料以及同学的帮助下最后都得到了解决，在此过程中，我不仅学到了很多知识，也提高了自己解决问题的能力，尤其是学会如何从大量的信息中筛选出所需有用的信息，同时我更加深刻的体会到了，虽然书本上的大部分知识都是有价值，正确的，但实际上每个人编程的思路和对数据处理的方法、思想都是不同的，这就要求我们一定要通过实践才能找到解决问题的方案。在此次毕业设计活动中，我不断的提高了自己，也得到了宝贵的经验，我相信这些对我以后的发展都会有很大帮助。
通过这次农产品推广系统APP的开发，我参考了很多相关系统的例子，取长补短，吸取了其他系统的长处，逐步对该系统进行了完善，但是该系统还是有很多的不足之处，有待以后进一步学习。
实践证明，农产品推广系统APP有着非常好的发展前景，经过测试运行，系统各项功能都十分完善，界面漂亮，使用方便，操作容易，在技术理论上已经成熟。
致 谢
大学的学习生活在这个季节将结束，但是在我的生命这仅仅只是一个逗号，我将面对另一个的开始。通过这次毕业设计的整个开发过程，从需求分析到具体功能实现，再到最终测试和维护的理解有了很大的进步，让我对系统开发有了更深刻的认识，对我个人的实践能力和解决问题的能力，都有了很大的帮助。这是这次毕业设计最大的收获。
