使用mybatis-generator自动生成model、dao、mapping文件

参考文献：http://www.cnblogs.com/smileberry/p/4145872.html

一、所需库

1、mybatis-generator库

2、连接DB的驱动（此以mysql为例，为mysql-connector）

二、目录结构

当前目录结构如下：

<?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="D:\eclipse\workspace\mylib\mybatis_generator\mysql-connector-java-5.1.38.jar"/>
<context id="DB2Tables"    targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/>
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!--数据库链接地址账号密码-->
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://192.168.6.131:3306/zhxpost" userId="xiaozhang" password="123456"></jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!--生成Model类存放位置-->
<javaModelGenerator targetPackage="zsm.model" targetProject="HeHeTest">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!--生成映射文件存放位置-->
<sqlMapGenerator targetPackage="zsm.mapping" targetProject="HeHeTest">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!--生成Dao类存放位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="zsm.dao" targetProject="HeHeTest">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!--生成对应表及类名-->
<table tableName="test_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>

3、在 generatorConfig.xml 右键运行即可，就会在该项目下根据配置文件生成相应文件，如下：
