MyBatis-4 逆向工程(generator)

MyBatis的逆向工程(generator)

通过数据库中相对应的表来生成dao,bean,xml映射文件
MyBatis generator官网:“http://www.mybatis.org/generator/index.html"

1.引入 mybatis-generator 的 jar 包,并解压

2.创建 generator 的配置文件

generator.xml文件的配置

<?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">
<!-- generato.jar路径 -->
<generatorConfiguration>
  <classPathEntry location="E:\\MyBatisGenerator" />
<!-- 加载数据库驱动 -->
  <context id="DB2Tables" targetRuntime="MyBatis3">
 <!-- 是否生成注解-->
     <commentGenerator>
        <property name="suppressDate" value="true"/>
        <property name="suppressAllComments" value="true" />
     </commentGenerator>
    <jdbcConnection driverClass="com.mysql.jdbc.Driver" 
        connectionURL="jdbc:mysql://localhost:3306/mybatis"
        userId="root"
        password="123456">
    </jdbcConnection>
<!-- 是否允许大数据 -->
    <javaTypeResolver >
      <property name="forceBigDecimals" value="false" />
    </javaTypeResolver>
<!-- 生成实体类配置 -->
    <javaModelGenerator targetPackage="com.huawei.lb.bean" targetProject="./src">
      <property name="enableSubPackages" value="true" />
      <property name="trimStrings" value="true" />
    </javaModelGenerator>
<!-- 生成<u>mapper</u>配置文件 -->
    <sqlMapGenerator targetPackage="com.huawei.lb.mapper"  targetProject="./resources">
      <property name="enableSubPackages" value="true" />
    </sqlMapGenerator>
<!-- 生成操作类配置 -->
    <javaClientGenerator type="XMLMAPPER" targetPackage="com.huawei.lb.dao"  targetProject="./src">
      <property name="enableSubPackages" value="true" />
    </javaClientGenerator>
<!-- 数据库对应的表 -->
    <table schema="DB2ADMIN" tableName="Users" domainObjectName="Users" enableCountByExample="flase" 
        enableDeleteByExample="flase" enableSelectByExample="flase" enableUpdateByExample="flase">
      <property name="useActualColumnNames" value="true"/>
      <generatedKey column="ID" sqlStatement="DB2" identity="true" />
      <columnOverride column="DATE_FIELD" property="startDate" />
      <ignoreColumn column="FRED" />
      <columnOverride column="LONG_VARCHAR_FIELD" jdbcType="VARCHAR" />
    </table>
    
  </context>
</generatorConfiguration>
