插件：这里Tomcat做测试用，注意Tomcat中的servlet与依赖中的servlet的冲突，可以配置依赖servlet的scope，<scope>providedscope>

         插件中的 是插件管理，如果要运行Tomcat，需要注释掉这个插件管理

配置web.xml:

配置springmvc的核心配置文件：

       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"

mybatis核心配置文件：

        "http://mybatis.org/dtd/mybatis-3-config.dtd">

   
   
    
        
        
    

    
    
        
        
        
        
        
    

   

db.properties：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/kgc1?zeroDateTimeBehavior=convertToNull
jdbc.username=root
jdbc.password=123456

 

mbg逆向生成配置文件：

        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
