小結一下ibatis框架下，傳入引數為陣列型別或者是List型別的sql寫法。特別說明，iterate標籤僅支援陣列和List型別，如果傳入Set，Map或其它集合型別，Ibatis會拋異常。

    1. 傳入陣列型別，不需要標明parameterClasss，陣列和List型別物件一樣都可以用<iterate>標籤進行遍歷。

<select id="selectOrgIdByNameStr" resultClass="Integer">
	SELECT id
	FROM org
	WHERE name IN
		<iterate close=")" open="("  conjunction=",">
            <![CDATA[
                 #[]# 
            ]]> 
       </iterate> 
</select>
 

    java呼叫程式碼（注意空指標問題）：

@Override
public List<Integer> selectOrgIdByNameStr(String[] orgArchArr) {
	 return baseDao.queryForList("org.selectOrgIdByNameStr", orgArchArr, String.class);
}

    2.傳入List型別，泛型引數是八大基本類。這個時候parameterClass傳的是List介面的類路徑，而不是List的泛型引數的類路徑！

<select id="searchWaiters" parameterClass="java.util.List" resultClass="com.chat.domain.zone.WaiterCgExt">
	SELECT *
	FROM waiter w, org o
	WHERE o.id = w.org_id
		AND w.id IN <iterate open="(" close=")" conjunction=",">
			#wid[]#
		</iterate>
</select>
 

    java呼叫程式碼如下，注意空指標問題。

@Override
public List<WaiterCgExt> searchWaiters(ModAccManVo vo) {
	List<Integer> widList = baseDao.queryForList("zone.waiter.searchWaitersId", vo, Integer.class);
	if(CollectionUtils.isEmpty(widList)) {
		return new ArrayList<WaiterCgExt>();
	}
	return baseDao.queryForList("zone.waiter.searchWaiters", widList, WaiterCgExt.class);
}
 

<select id="selectWaitersByOrgList" resultClass="com.chat.domain.zone.Waiter" parameterClass="java.util.List">
	SELECT id, pin as userName
	FROM waiter
	WHERE org_id IN 
	 	<iterate open="(" close=")" conjunction=",">  
        	#list[].id#  
        </iterate>   
</select>

<select id="query" resultClass="BopEntityTag" parameterClass="map">
    Select *
    FROM ***_tag
    WHERE tag_value != 0
    <isNotNull property="q.codeSet" prepend="AND"> code IN
        <iterate open="(" close=")" conjunction="," property="q.codeSet"> #q.codeSet[]# </iterate>
    </isNotNull>
</select>

@Override
public List<BopEntityTagDO> query(***TagDO query) {
	Map<String, Object> params = new HashMap<String, Object>();
	params.put("q", query);
	......
	return queryForList(getStatementName("query"), params);
}
