mybatis xml中使用where 条件中的in方法

<select id="queryCount" resultType="cn.bnsr.edu_yun.view.FileView">
      SELECT sum(download_times) as downloadNum ,sum(click_times) as browseNum
      FROM  file_property 
    <if test="_parameter != null">
      WHERE id in 
         <foreach item="item" index="index" collection="list" open="(" separator="," close=")">  
             #{item}  
           </foreach>  
      </if>
  </select>

如上方法使用in，

　　注意，传入的参数是List<Long> ，如果传入的是array 则需要修改collection="list"部分定义为 collection="array"
