mybatis-generator.xml  内容为

                type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口

        -->

        <javaClientGenerator type="XMLMAPPER" targetPackage="com.demo.dao" targetProject="src/test/java">

        <!--生成对应表及类名-->

        <table tableName="sys_user" domainObjectName="sysUser" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

        <table tableName="sys_menu" domainObjectName="sysMenu" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>

    </context>

</generatorConfiguration>

配置成功后，如果是idea  则打开maven-plugns  找到 mybatis-generator plugn 展开后  双击执行  mybatis-generator:generate
