mybatis 查詢SQL參數爲map

xml 中使用 param. 獲取

<select id="findTasks" parameterType="java.util.Map" resultMap="BaseResultMap">
    select 
    <include refid="Base_Column_List"/>
    from tasks
    where 1=1
      <if test="params.taskId != null">
        and task_id = #{params.taskId}
      </if>
      <if test="params.taskStatus != null">
        and task_status = #{params.taskStatus}
      </if>
      <if test="params.taskName != null">
        and task_name = #{params.taskName}
      </if>
      <if test="params.orderBy != null and params.orderBy == 'start_time asc'.toString()">
        order by tasks.start_time asc
      </if>
      <if test="params.orderBy != null and params.orderBy == 'start_time desc'.toString()">
        order by tasks.start_time desc
      </if>
      <if test="params.orderBy != null and params.orderBy == 'end_time asc'.toString()">
        order by tasks.end_time asc
      </if>
      <if test="params.orderBy != null and params.orderBy == 'end_time desc'.toString()">
        order by tasks.end_time desc
      </if>
      <!-- limit #{params.start},#{params.pageSize} -->
  </select>
