mybatis generator命令行生成代码
1下载文件
mysql-connector-java-5.1.43.jar 和 mybatis-generator-core-1.3.5.jar 推荐去maven仓库搜索下载,不用积分,可以挑版本。https://mvnrepository.com/
2 配置文件(跟着注释一步一步改就行了)

<!-- 一、修改数据库驱动包位置 -->
<classPathEntry location="D:\java\mybatis\mysql-connector-java-5.1.43.jar" />
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!-- 二、修改数据库链接URL、用户名、密码 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/mycoupon?characterEncoding=utf8" userId="root" password="123456">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- 三、修改生成实体类包名和位置 -->
<javaModelGenerator targetPackage="entity" targetProject="D:\java\mybatis\code">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- 四、生成的映射文件XML包名和位置 -->
<sqlMapGenerator targetPackage="mapping" targetProject="D:\java\mybatis\code">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!-- 五、生成DAO的包名和位置 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="mapper" targetProject="D:\java\mybatis\code">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<!-- 六、选择要生成那些表(例子:修改下面tableName和domainObjectName的地方就行) -->
<table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
<table tableName="t_coupon" domainObjectName="Coupon" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
</context>
</generatorConfiguration>
<!--
生成命令行:
java -jar mybatis-generator-core-1.3.5.jar -configfile generator.xml -overwrite
