mybatis传参为map的写法

XxlJobInfo getInfoByParameters(@Param("param") Map<String, String> param);

<select id="getInfoByParameters"  resultMap="XxlJobInfo">
        SELECT * FROM xxl_job_info WHERE 1=1
        <choose>
            <when test="param.jobId!=null and param.jobId!=''">
                AND id = #{param.jobId}
            </when>
            <otherwise>
                AND job_desc = #{param.jobName} AND job_group = #{param.jobGroup}
            </otherwise>
        </choose>
    </select>
