Integration SSM

SSM steps to achieve integration login:

1. Import all the jar package
2. Add all configuration files, convert config folder for the resource folder
3. Add character encoding filter in web.xml, registered springmvc and spring framework
4. Realize the function of all profiles
5. Mybatis use reverse engineering to automatically generate pojo, generate mapper interfaces and file mapper.xml
6. New service interface and implementation class, completion administrator login
7. New controller, complete the login function
8. Add pages, images, CSS
9. Rectification html page to jsp page
10. Test function

jar package:

Profile:
jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/xiaomissm?characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456

Use of reverse engineering mybatis:
Mybatis Reverse Engineering used to automatically generate the corresponding database table POJO, and generating an interface mapper mapper.xml file, a key to complete the entire process, eliminating the need for the use of the process we prepared mybatis sql mapping framework.
Mybatis reverse engineering the main configuration file generatorConfig.xml:
