注意generatorConfig.xml的路径
下面是generatorConfig.xml的代码

< ?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> < !-- 本地数据库驱动程序jar包的全路径 --> < classPathEntry location="C:/mysql-connector-java-8.0.15.jar"/> < context id="context" targetRuntime="MyBatis3"> < commentGenerator> < property name="suppressAllComments" value="https://www.songbingjia.com/android/false"/> < property name="suppressDate" value="https://www.songbingjia.com/android/true"/> < /commentGenerator> < !-- 数据库的相关配置 --> < jdbcConnection driverClass="com.mysql.cj.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/dtpt?serverTimezone=UTC" userId="rong" password="123456"/> < javaTypeResolver> < property name="forceBigDecimals" value="https://www.songbingjia.com/android/false"/> < /javaTypeResolver> < !-- 实体类生成的位置 --> < javaModelGenerator targetPackage="com.example.pojo" targetProject="src/main/java"> < property name="enableSubPackages" value="https://www.songbingjia.com/android/false"/> < property name="trimStrings" value="https://www.songbingjia.com/android/true"/> < /javaModelGenerator> < !-- *Mapper.xml 文件的位置 --> < sqlMapGenerator targetPackage="mybatis" targetProject="src/main/java"> < property name="enableSubPackages" value="https://www.songbingjia.com/android/false"/> < /sqlMapGenerator> < !-- Mapper 接口文件的位置 --> < javaClientGenerator targetPackage="com.example.mapper" targetProject="src/main/java" type="XMLMAPPER"> < property name="enableSubPackages" value="https://www.songbingjia.com/android/false"/> < /javaClientGenerator> < !-- 相关表的配置 --> < table tableName="t_user" domainObjectName="UserDTO" enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false" enableUpdateByExample="false"/> < /context> < /generatorConfiguration>

然后双击运行这个
