system description

The main development purpose of this system is to facilitate library managers to manage library information , Increase work efficiency , The customer group is the staff of libraries and bookstores at all levels . According to the requirements of this system , Combined with the actual management situation , The application of this system has the following functional modules ：  1. Basic information settings ： Such as the editor of the operator , Modification of operator password . 2. User management ： Can increase （ members ）、 modify 、 Delete user information . 3. Book information management ： Can increase 、 Delete 、 Modify book information, etc . 4. Search for book information . 5. Add book borrowing information . 6. Borrowing and returning function . The function diagram of the system administrator is shown in the figure 3-2 Shown

 

Environmental needs

1. Running environment ： It is best to java jdk 1.8, We run on this platform . Other versions can, in theory .
2.IDE Environmental Science ：IDEA,Eclipse,Myeclipse Fine . recommend IDEA;
3.tomcat Environmental Science ：Tomcat 7.x,8.x,9.x All versions are available
4. Hardware environment ：windows 7/8/10 1G Above memory ; perhaps Mac OS; 
5. database ：MySql 5.7 edition ;
6. whether Maven project ： no ;

Technology stack

1. Back end ：Spring+SpringMVC+Mybatis
2. front end ：JSP+CSS+JavaScript+jQuery

Instructions

1. Use Navicat Or other tools , stay mysql Create a database with the corresponding name in , And import the sql file ;
2. Use IDEA/Eclipse/MyEclipse Import the project ,Eclipse/MyEclipse Import time , if maven Item, please select maven;
if maven project , After importing successfully, please execute maven clean;maven install command , And then run ;
3. In the project springmvc-servlet.xml Change the database configuration in the configuration file to your own configuration ;
4. Run the project , Enter... In the browser http://localhost:8080/ Sign in
