mybatis逆向工程官方网站：http://www.mybatis.org/generator/quickstart.html                                                              

• 准备xml文件。如下generator.xml全部内容

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>

  <properties resource="db.properties"/>
  
  <context id="mbg" targetRuntime="MyBatis3">
    <jdbcConnection driverClass="${jdbc.driverClass}"
        connectionURL="${jdbc.url}"
        userId="${jdbc.user}"
        password="${jdbc.password}">
    </jdbcConnection>

    <javaTypeResolver>
      <property name="forceBigDecimals" value="false" />
    </javaTypeResolver>

    <javaModelGenerator targetPackage="com.lw.entity" targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator>

    <sqlMapGenerator targetPackage="com.lw.dao"  targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>

    <javaClientGenerator type="XMLMAPPER" targetPackage="com.lw.dao"  targetProject="src/main/java">
      <property name="enableSubPackages" value="true" />
    </javaClientGenerator>

    <table tableName="tk_dg_coupon" domainObjectName="TkDgCoupon" >
        
    </table>

  </context>
</generatorConfiguration>

• 上面generator.xml中引入的资源文件db.properties如下：

######mysql#####
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/common
jdbc.user=root
jdbc.passsord=123456

• pom文件配置如下，重点注意build标签的配置：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

• 右键项目执行run as---->Maven build ---->写入命令mybatis-generator:generate 即可

Maven构建成功
