首先是pom依賴
<dependency>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-core</artifactId>
<version>1.3.7</version>
</dependency>
然後是pom插件
<build>
<plugins>
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.7</version>
</plugin>
</plugins>
</build>
然後在項目根目錄resources下面放置 generatorConfig.xml 檔案

内容如下(自己相應改下):
<?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>
<!-- 資料庫驅動:選擇你的本地硬碟上面的資料庫驅動包-->
<classPathEntry location="D:\javaOthers\java_jar\mysql-connector-java-8.0.19.jar"/>
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/>
<!-- 是否去除自動生成的注釋 true:是 : false:否 -->
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!--資料庫連結URL,使用者名、密碼 -->
<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=Asia/Shanghai" userId="root" password="black123">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 生成模型的包名和位置-->
<javaModelGenerator targetPackage="com.gbx.springboot.vue.demo.model" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!-- 生成映射檔案的包名和位置-->
<sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 生成mapper位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.gbx.springboot.vue.demo.dao" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 要生成的表 tableName是資料庫中的表名或視圖名 domainObjectName是實體類名-->
<table tableName="sys_dept" domainObjectName="SysDept" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="sys_group" domainObjectName="SysGroup" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="sys_permission" domainObjectName="SysPermission" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="sys_permission_operation_log" domainObjectName="SysPermissionOperationLog" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="sys_role" domainObjectName="SysRole" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
<table tableName="sys_user" domainObjectName="SysUser" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>
然後把對應的資料庫驅動放在 generatorConfig.xml 約定的位置(與你pom裡依賴的版本的要一緻):
然後添加運作項:
填寫的指令如下:
mybatis-generator:generate -e
然後選擇運作項,啟動運作:
運作成功後成功添加新的檔案:
