第一种方式：
配置maven插件
在src/main/resources下新建generatorConfig.xml 内容如下：
<?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>
<context id="sqlserverTables" targetRuntime="MyBatis3">
<!-- 生成的pojo，将implements Serializable-->
<plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin>
<commentGenerator>
<!-- 是否去除自动生成的注释 true：是 ： false:否 -->
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!-- 数据库链接URL、用户名、密码 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://127.0.0.1:3306/thinkphp?useUnicode=true&characterEncoding=UTF-8"

password="root">
</jdbcConnection>
<!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer
true，把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal
-->
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- 生成model模型，对应的包路径，以及文件存放路径(targetProject)，targetProject可以指定具体的路径,如./src/main/java，
也可以使用“MAVEN”来自动生成，这样生成的代码会在target/generatord-source目录下
-->
<!--<javaModelGenerator targetPackage="com.joey.mybaties.test.pojo" targetProject="MAVEN">-->
<javaModelGenerator targetPackage="com.kongzhong.gw2.ccc.mapper" targetProject="./src/main/java">
<property name="enableSubPackages" value="true"/>
<!-- 从数据库返回的值被清理前后的空格 -->
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!--对应的mapper.xml文件 -->
<sqlMapGenerator targetPackage="com.kongzhong.gw2.ccc.mapper" targetProject="./src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 对应的Mapper接口类文件 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.kongzhong.gw2.ccc.mapper" targetProject="./src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 列出要生成代码的所有表，这里配置的是不生成Example文件 -->
<table tableName="tp_user" domainObjectName="User"
enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false"
enableSelectByExample="false" selectByExampleQueryId="false" >
<property name="useActualColumnNames" value="false"/>
