mybatis返回map，key为指定属性，value为实体类结果集

实体类：

数据库：

CREATE TABLE `job_title_info` (
  `_jobtitleid` varchar(255) DEFAULT NULL,
  `_shortname` varchar(255) DEFAULT NULL,
  `_fullname` varchar(255) DEFAULT NULL,
  `_departmentid` varchar(255) DEFAULT NULL,
  `_jobresponsibility` varchar(255) DEFAULT NULL,
  `_jobcompetency` varchar(255) DEFAULT NULL,
  `_jobdoc` varchar(255) DEFAULT NULL,
  `_jobtitleremark` varchar(255) DEFAULT NULL,
  `lastChangdate` varchar(255) DEFAULT NULL,
  `jobactivitycode` varchar(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

mapper：

<select id="listJobTitleAsMap" resultMap="jobTitleMap">
   select * from oa_job_title_info;
</select>
<resultMap id="jobTitleMap" type="com.bootdo.oa.domain.JobTitleBean">
   <result column="_jobtitleid" property="_jobtitleid" javaType="String"/>
   <result column="_shortname" property="_shortname" javaType="String"/>
   <result column="_fullname" property="_fullname" javaType="String"/>
   <result column="_departmentid" property="_departmentid" javaType="String"/>
   <result column="_jobresponsibility" property="_jobresponsibility" javaType="String"/>
   <result column="_jobcompetency" property="_jobcompetency" javaType="String"/>
   <result column="_jobdoc" property="_jobdoc" javaType="String"/>
   <result column="_jobtitleremark" property="_jobtitleremark" javaType="String"/>
   <result column="lastChangdate" property="_lastChangdate" javaType="String"/>
   <result column="_code" property="_code" javaType="String"/>
</resultMap>

mapper接口：这里指定_jobtitleid为map的key

@Mapper
public interface AxisHRDao {

	@MapKey("_jobtitleid")
	Map<String,JobTitleBean> listJobTitleAsMap();

}

结果：

mybatis返回map，key为指定属性，value为实体类结果集
