Because it is C2C Project , Therefore, the project does not need background management .


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. whether Maven project : yes ; See if the source directory contains pom.xml; If included , Then for maven project , Otherwise, it is not maven project  
6. database :MySql 5.7 edition ;


Technology stack

1. Back end :Spring SpringMVC MyBatis
2. front end :Thymeleaf+Html+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 , To configure tomcat, And then run ;
3. In the project jdbc.properties Change the database configuration in the configuration file to your own configuration ;
4. Run the project , Input localhost:8080/xxx Sign in
