1,pom添加依赖：

<plugins>  

    <plugin>         <groupId>org.mybatis.generator</groupId>         <artifactId>mybatis-generator-maven-plugin</artifactId>         <version>1.3.2</version>         <configuration>           <verbose>true</verbose>           <overwrite>true</overwrite>         </configuration>       </plugin>     </plugins>

 

2，在src/main/resource下 添加配置： 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>       <classPathEntry  location="D:\E_Dist\mvn_localRepository\mysql\mysql-connector-java\5.1.40\mysql-connector-java-5.1.40.jar"/>            <context id="dataSource_A"  defaultModelType="flat" >                <commentGenerator>               <property name="suppressDate" value="true"/>               <property name="suppressAllComments" value="true"/>           </commentGenerator>                    <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/test"                 userId="root" password="open123">           </jdbcConnection>                    <javaTypeResolver>               <property name="forceBigDecimals" value="false"/>           </javaTypeResolver>                    <javaModelGenerator targetPackage="src.main.java.com.xxf.coffee_erp.datasource.coffee_erp.bean"                             targetProject="D:\E_Dist\IDEA_WorkSpace\datasource_coffeeErp_main">             <property name="enableSubPackages" value="true"/>               <property name="trimStrings" value="true"/>           </javaModelGenerator>                  <sqlMapGenerator targetPackage="src.main.java.com.xxf.coffee_erp.datasource.coffee_erp.mapper"                           targetProject="D:\E_Dist\IDEA_WorkSpace\datasource_coffeeErp_main">             <property name="enableSubPackages" value="true"/>           </sqlMapGenerator>                    <javaClientGenerator type="XMLMAPPER" targetPackage="src.main.java.com.xxf.coffee_erp.datasource.coffee_erp.dao"                              targetProject="D:\E_Dist\IDEA_WorkSpace\datasource_coffeeErp_main">             <property name="enableSubPackages" value="true"/>           </javaClientGenerator>                  <table tableName="%" schema="general"                 enableCountByExample="false"                  enableUpdateByExample="false" enableDeleteByExample="false"                  enableSelectByExample="false" selectByExampleQueryId="false">                 <property name="useActualColumnNames" value="true"/>                 <generatedKey column="id" sqlStatement="MySql" identity="true"/>         </table>   </context>     </generatorConfiguration>

 

3，在Intellij IDEA添加一个“Run运行”选项，使用maven运行mybatis-generator-maven-plugin插件 ：

    

     之后弹出运行配置框，为当前配置配置一个名称，这里其名为"generator",然后在 “Command line” 选项中输入“mybatis-generator:generate  -e”
