使用Mybatis-Generator自动生成Model、Mapper相关文件

1、首先需要下载一下MyBatis Generator
2、解压mybatis-generator-**.zip
3、将mybatis-generator-core-**.jar，数据库驱动，存放的在一起

4、generatorConfig.xml

<?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>  <!--数据库驱动-->  <classPathEntry location="postgresql-9.4.1212.jre7.jar" />  <context id="context1">    <!--数据库链接地址账号密码-->    <jdbcConnection driverClass="org.postgresql.Driver"                        connectionURL="jdbc:postgresql://172.20.68.242:5432/happinet" userId="postgres"                        password="happinet" />    <!--生成Model类存放位置-->    <javaModelGenerator targetPackage="cn.pzh.model" targetProject="src/main/java/" />    <!--生成映射文件存放位置-->    <sqlMapGenerator targetPackage="cn.pzh.mapper" targetProject="src/main/resources/" />    <!--生成Mapper接口存放位置-->    <javaClientGenerator targetPackage="cn.pzh.mapper" targetProject="src/main/java/" type="XMLMAPPER" />    <!--生成对应表及类名，tableName="%"代表所有表-->    <table schema="public" tableName="%" enableInsert="true"            enableSelectByPrimaryKey="true"            enableSelectByExample="false"            enableUpdateByPrimaryKey="true"            enableUpdateByExample="false"            enableDeleteByPrimaryKey="true"            enableDeleteByExample="false"            enableCountByExample="false"            selectByExampleQueryId="false"            modelType="hierarchical">    </table>  </context></generatorConfiguration>

5、执行命令生成

java -jar mybatis-generator-core-1.3.5.jar -configfile generatorConfig.xml -overwrite
