IDEA和maven实现逆向工程

.

1、概念
MyBatis逆向工程是指用数据库的表直接生成Java代码，利用MyBatis官方提供的逆向工程，可以针对单表自动生MyBatis执行所需要的代码（如pojo，mapper接口和mapper.xml）
2、步骤
2.1创建默认maven工程
2.2在pom.xml增加mybatis-generator插件，版本：1.3.5

   
   
       
            org.mybatis.generator
            mybatis-generator-maven-plugin
            1.3.5
           
                true
                true
           
       
   

2.3在资源目录下添加配置文件generatorConfig.xml

        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

   
   

   
   

   
 
       
           
           
       

       
                        driverClass="com.mysql.jdbc.Driver"
                connectionURL="jdbc:mysql://localhost:3306/jd?useSSL=false"
                userId="root"
                password="root">
       

       
       
           
       

 

       
                                    targetProject="src/main/java">
           
           
           
           
           
           
           
           
       

       
                                 targetProject="src/main/java">
           
       

       
                                     targetPackage="com.bj169.mapper"
                             targetProject="src/main/java">
           
       

       
       

               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false">
       
                       enableCountByExample="true" enableUpdateByExample="true"
               enableDeleteByExample="true" enableSelectByExample="true"
               selectByExampleQueryId="true">
       

   

2.4使用maven运行mybatis-generator-maven-plugin插件

点击 run菜单 -> Edit Configurations
