Abstract
With the development of society, all aspects of society are making use of the advantages of the information age. The advantages and popularity of the Internet make the development of various systems necessary.
In this paper, the actual use of the development background, the use of software engineering principles and development methods, it is mainly using java language technology and MySQL database to complete the design of the system. In the whole development process, firstly, the demand analysis of wechat ordering applet is carried out, and the main functions of wechat ordering applet are obtained. Then the overall design and detailed design of wechat ordering small program are carried out. The overall design mainly includes the function design, the overall structure design, the data structure design and the security design of the small program; the detailed design mainly includes the implementation of the database access of the wechat ordering small program, the specific implementation of the main function modules, and the key code of the module implementation. Finally, the function test of wechat ordering app is carried out, and the test results are analyzed and summarized. The shortcomings of wechat ordering app and the places that need to be improved are obtained, which provides convenience for the maintenance of wechat ordering app in the future, and also provides reference and help for the development of similar wechat ordering app in the future.
The development of wechat ordering applet makes the system more convenient and efficient, and also makes wechat ordering applet more systematic and orderly. The system interface is friendly and easy to operate.
Key words: wechat ordering applet; Java language, MySQL database, SSM framework
