Intellij IDEA 中使用 MyBatis-generator 自动生成 MyBatis 代码

1、IDEA创建maven工程（略）

2、 在maven项目的pom.xml 添加mybatis-generator-maven-plugin 插件和MySQL数据库驱动依赖

<build>
 <plugins>
 <plugin>
 <groupId>org.mybatis.generator</groupId>
 <artifactId>mybatis-generator-maven-plugin</artifactId>
 <version>1.3.5</version>
 <configuration>
 <verbose>true</verbose>
 <overwrite>true</overwrite>
 </configuration>
 </plugin>
 </plugins></build><dependency>
 <groupId>mysql</groupId>
 <artifactId>mysql-connector-java</artifactId>
 <version>5.1.34</version></dependency>

3、在maven项目下的src/main/resources 目录下建立名为 generatorConfig.xml的配置文件，作为mybatis-generator-maven-plugin 插件的执行目标，模板如下：

<?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>
 <!-- 配置mysql 驱动jar包路径.用了绝对路径 -->
 <classPathEntry location="/Users/wangyongzhi/.m2/repository/mysql/mysql-connector-java/5.1.34/mysql-connector-java-5.1.34.jar" />
 <context id="wangyongzhi_mysql_tables" targetRuntime="MyBatis3">
 <!-- 防止生成的代码中有很多注释，加入下面的配置控制 -->
 <commentGenerator>
 <property name="suppressAllComments" value="true" />
 <property name="suppressDate" value="true" />
 </commentGenerator>
 <!-- 数据库连接 -->
 <jdbcConnection driverClass="com.mysql.jdbc.Driver"
 connectionURL="jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&amp;characterEncoding=UTF-8"
 userId="root"
 password="123456">
 </jdbcConnection>
 <javaTypeResolver >
 <property name="forceBigDecimals" value="false" />
 </javaTypeResolver>
 <!-- 数据表对应的model层 -->
 <javaModelGenerator targetPackage="me.zhige.domain" targetProject="src">
 <property name="enableSubPackages" value="true" />
 <property name="trimStrings" value="true" />
 </javaModelGenerator>
 <!-- sql mapper 映射配置文件 -->
 <sqlMapGenerator targetPackage="me.zhige.mapper" targetProject="src">
 <property name="enableSubPackages" value="true" />
 </sqlMapGenerator>
 <!-- mybatis3中的mapper接口 -->
 <javaClientGenerator type="XMLMAPPER" targetPackage="me.zhige.dao" targetProject="src">
 <property name="enableSubPackages" value="true" />
 </javaClientGenerator>
 <!-- 数据表进行生成操作 schema:相当于库名; tableName:表名; domainObjectName:对应的DO -->
 <table schema="test" tableName="users" domainObjectName="User"
 enableCountByExample="false" enableUpdateByExample="false"
 enableDeleteByExample="false" enableSelectByExample="false"
 selectByExampleQueryId="false">
 </table>
 </context></generatorConfiguration>

4、使用maven运行mybatis-generator-maven-plugin插件：工程名->Plugins->mybatis-generator->mybatis-generator:generate->Run Maven Build

5、自动生成的结构如下：
