利用mybatis-generator自动生成代码

1、准备生成代码需要的文件和jar包（下载地址）

2、配置generatorConfig.xml文件

<?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="mysql-connector-java-5.1.39.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://localhost/ssm" userId="root" password="">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!--生成Model类存放位置-->
<javaModelGenerator targetPackage="com.loong.model" targetProject="src">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!--生成映射文件存放位置-->
<sqlMapGenerator targetPackage="com.loong.mapping" targetProject="src">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!--生成Dao类存放位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.docworks.dao" targetProject="src">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!--生成对应表及类名-->
<table tableName="t_user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>

3、在有jar包的文件夹上右键打开命令窗口，执行如下命令

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