解决字段名与实体类属性名冲突

Posted 2022-09-15 kfsrex

1.在查询时给字段起别名，让别名和实体类属性名一样

<!-- 通过id查询 -->        <select id="selectById" parameterType="int"               resultType="com.zhiyou100.kfs.bean.Users">               select id as uid,name uname,age uage from users where id=#id        </select>

 

 

2.通过mybatis的resultMap标签设置对应关系

<select id="selectById" parameterType="int"               resultMap="myMap">               select id,name,age from users where id=#id        </select>        <resultMap type="com.zhiyou100.kfs.bean.Users" id="myMap">               <id column="id" property="uid"/>               <result column="name" property="uname"/>               <result column="age" property="uage"/>        </resultMap>
