mybatis傳入字串，集合，陣列並遍歷

<!--傳遞引數為字串approveStatus =“通過,不通過” item為遍歷後的引數-->
<if test="approveStatus != null and approveStatus!=''">
      and i.approve_status IN
        <foreach item="status" collection="approveStatus.split(',')" open="(" separator="," close=")">
            #{
 
status}
        </foreach>
</if>

<!--傳遞引數為集合approveStatusList，集合中包含物件user ,approveStatusList={user1,user2 } -->
<if test="approveStatusList!= null and approveStatusList.size>0 ">
				AND operate_user in
				<foreach collection="approveStatusList" open="(" close=")" separator=
 
"," item="user" index="index">
					#{user.userName}
				</foreach>
			</if>

<!--傳遞引數為陣列approveStatus =[通過,不通過] 此時collection必須為array item為傳遞的陣列引數，且引數名要保持一致-->
<if test="approveStatus != null and approveStatus!=''">
      and i.approve_status IN
