1.1 Research Background
Nowadays, the Internet is developing rapidly and the network is spread all over the world. The domestic mobile information field is unique. News released through WeChat can be quickly and conveniently spread to every corner of the world, and the information that can be spread on the Internet is also very wide, such as Text, pictures, sounds, videos, etc. Therefore, these various benefits have made the Internet the main way for information dissemination. All kinds of information in society are trying their best to spread through the Internet, and the Internet has an increasing impact on society.
Therefore, the development of a suitable Yijiawang Fresh Food Cloud Order Retail System can facilitate management of the Yijiawang Fresh Food Cloud Order Retail System and improve information management efficiency and query efficiency. Users can use the WeChat applet on their mobile phones It is more convenient to order food and it is conducive to better serving people.
1.2 Research Purpose
With the rapid development of Internet technology and the advent of the Internet era, network information will also change today's society. All walks of life are also slowly converging towards standardization and networking in terms of daily business operations and management. The degree of informatization of Yijiawang's fresh food cloud order retail system is reflected in the application of the Internet and information technology to operations and management, and the replacement of traditional manual work with modern tools. Undoubtedly, the use of network information management makes information management more advanced, more efficient, more scientific, and information exchange faster.
For the previous management of Yijiawang Fresh Cloud Order Retail System, most of them were managed using traditional manual methods, which resulted in low management efficiency and high error frequency. Moreover, over time, the accumulated data information is not easy to save, which will cause many problems for query, update and maintenance. There are also great hidden dangers in data handover. If electronic storage is adopted, it will bring great improvements and bring great convenience to users' inquiries. Therefore, it is urgent to design a Yijiawang fresh food cloud order retail system, which can improve the level of information management.
1.3 System design ideas
A successful website should clearly define the purpose of building the website, determine the functions of the website, determine the scale of the website, investment costs, and conduct necessary market analysis, etc. Only detailed planning can avoid many problems that occur during website construction and ensure that website construction can proceed smoothly. At the same time, a large-scale computer website system must have a correct design guiding ideology, and form a complete network architecture through reasonable selection of data structure, network structure, operating system and development environment, in order to give full play to the advantages of computer information management. Based on the actual needs of netizens in real life, this system is designed according to the following principles.
1. Effectiveness: In fact, effectiveness here includes two aspects: usefulness and usability. Usefulness refers to the potential of a site to meet user needs, while usability refers to the ability to achieve specific goals through the operation of the site. It can be seen that a site is not a good site if it does not function properly or is poorly designed. A usable site should be highly efficient, easy to learn, and satisfying in achieving user goals without making mistakes.
2. High reliability: A practical website must be reliable at the same time. This design can ensure the reliability and fault tolerance of the website through reasonable and advanced network design and optimized selection of software and hardware.
3. High security: In the design, various security measures provided by network software and hardware will be fully utilized to ensure that users share resources and fully consider the requirements for disaster recovery, backup, and recovery of system and data resources. Provides powerful database backup tools for the system. The security of critical data can be guaranteed. Operation permission levels, set different roles to ensure the operation permissions of each step, can be set by the administrator.
4. Advancedness: Adopt the most advanced development technology in the world, use JSP development technology, and MYSQL as the website back-end database. The use of these technologies reduces future system operating costs and improves system stability and ease of maintenance.
5. Adopt standard technology: All designs of this website follow current international standards to improve the openness of the system.
6. Balance between appearance and technology: The system adopts a Web-style interface design, which is friendly, beautiful, easy to use, easy to learn and use. The key issue in website design is the balance between appearance and technology. A website that looks bad is annoying. The site may work well but fail to motivate users. On the contrary, if the appearance is very expressive but the technology is limited, users will be very disappointed. A clear and continuous relationship needs to be determined between appearance and technology, that is, appearance is related to the intention of the site, and different types of websites are treated differently.

2.4 Introduction to SSM framework
SSM framework is the abbreviation of Spring+Spring MVC+MyBatis. This is the current mainstream Java EE enterprise-level framework after SSH and is suitable for building various large-scale enterprise-level application systems.
1. Introduction to
Spring Spring is an open source framework. Spring is a lightweight Java development framework that emerged in 2003. It is derived from some of the concepts and prototypes expounded by Rod Johnson in his book Expert One-On-One J2EE Development and Design. Come. It was created to solve the complexities of enterprise application development. Spring uses basic JavaBeans to accomplish things that were previously only possible with EJBs. However, Spring's uses are not limited to server-side development. Any Java application can benefit from Spring in terms of simplicity, testability, and loose coupling. Simply put, Spring is a lightweight Inversion of Control (IoC) and Aspect-Oriented (AOP) container framework.
A. What is Inversion of Control (IOC)?
IOC: Inversion of control is also called dependency injection. The factory pattern is used to hand over the object to the container for management. You only need to configure the corresponding bean in the spring configuration file and set the relevant attributes to let the spring container generate instance objects and management objects of the class. When the spring container starts, spring will initialize all the beans you configure in the configuration file, and then when you need to call it, it will assign the beans it has initialized to the class you need to call these beans (assuming The class name is A), and the allocation method is to call the setter method of A to inject, without the need for you to new these beans in A.
B. What is aspect-oriented (AOP)?
First of all, it needs to be explained that AOP is just a feature of Spring. It is a programming idea like OOP, not a certain technology. AOP can be said to be a supplement and improvement to OOP. OOP introduces concepts such as encapsulation, inheritance, and polymorphism to establish an object hierarchy to simulate a collection of common behaviors. When we need to introduce public behavior to dispersed objects, OOP is powerless. In other words, OOP allows you to define relationships from top to bottom, but it is not suitable for defining relationships from left to right. For example, the logging function. Logging code tends to be spread horizontally across all object hierarchies, having nothing to do with the core functionality of the objects it's spread to. In OOP design, it leads to a large amount of code duplication, which is not conducive to the reuse of various modules. Encapsulate the cross-cutting business logic in the program (such as security, logs, transactions, etc.) into an aspect, and then inject it into the target object (specific business logic).
The technology to implement AOP is mainly divided into two categories: one is to use dynamic proxy technology to decorate the message by intercepting the message to replace the execution of the original object behavior; the other is to use static weaving to introduce A specific syntax creates "aspects" so that the compiler can weave in code about the "aspects" during compilation.
2. Introduction to Spring MVC
Spring MVC is a follow-up product of the Spring Framework and has been integrated into Spring Web Flow. The Spring features it natively supports make development very simple and standardized. Spring MVC separates the roles of controllers, model objects, dispatchers, and handler objects, making them easier to customize.
3. Introduction to MyBatis
MyBatis was originally an open source project iBatis of Apache. In 2010, the project was moved from Apache Software Foundation to Google Code and renamed MyBatis. MyBatis is a Java-based persistence layer framework. The persistence layer framework provided by iBATIS includes SQL Maps and Data Access Objects (DAO). MyBatis eliminates almost all JDBC code and manual setting of parameters and retrieval of result sets. MyBatis uses simple XML or annotations for configuration and original mapping, mapping interfaces and Java POJOs (Plain Old Java Objects, ordinary Java objects) into records in the database. It can be understood that MyBatis is a framework used to help you manage data additions, deletions, modifications and queries.
