Project Summary:

In the past, the management of colleges and universities mainly adopts manual management, there are problems such as information updating is not timely query, change and management information tedious manual management consumes a lot of manpower and material resources. It is very important to study and develop the employment management system for college graduates. This topic is based on Java language and MySQL database using Java Web, Springboot Technology design and development based on Javaweb, Springboot employment information management system for the school to provide a convenient and effective system to manage the employment information of college students this system mainly includes graduate management, enterprise information management, students on information management, information query and other functions to achieve the university biniu, the management of the situation, And the ability to record and query the graduates’ graduation test shows that the system allows stable and reliable application of the system can be conducive to the timely and comprehensive management of the graduates’ employment information, but also saves a lot of time and energy for the managers.

Background Java Controller login interface implementation

@ResponseBody @RequestMapping("/employment/login") public CommonResult<User> login(User user){ user.setUserPwd(MD5Util.getMD5(user.getUserPwd())); User loginUser = userService.getUserByAccount(user.getUserAccount()); if(loginUser == null || ! LoginUser. GetUserPwd (.) the equals (user getUserPwd ())) {return CommonResult. GenerateFailureResult (" account or password is incorrect ", 1, null); }else{ return CommonResult.generateSuccessResult(1, loginUser); }}Copy the code

Administrator homepage:

The login page and administrator page are used to manage employment information, statistics about employment information, user information, and exit.

​

Background main code implementation:

After successful login, the system switches to the background employment information list page to display data

Conclusion:

Through recent knowledge of Java object-oriented programming, front-end knowledge, and the Java Springboot framework, I understand the importance of learning Java. In the process of developing this system, I completed many experiments and tests. During this period of learning and development, I realized that I was already familiar with it and could use it independently. Through the understanding of Java, I found that it does have a lot of convenience, it integrates abstractness, encapsulation, inheritance and polymorphism, realizes code reuse and code extension, improves the efficiency of software development. Learning Java language well is very important for our major, so IN the development process of this project, I tried my best to understand Java programming ideas, master basic skills and learn as much knowledge as possible. My basic purpose of learning programming is to develop the key skills to solve practical problems with programming methods. Java object-oriented programming is a highly practical language. The MVC three-tier architecture of springMVC framework centralizes data access and logical operations into components, enhancing the reuse of the system. The expansibility of the system is greatly improved. As well as front-end jQuery, JS and CSS styles, I can make web page layouts, style adjustments and fonts more accurate.
