專案遇到：需要根據一個欄位的集合遍歷查詢資料，需要在mybatis使用傳入個Map<String Object>引數進行foreach遍歷查詢。

xml程式碼如下：

	<select id="selectByMr" resultMap="BaseResultMap">
		select 
		<include refid="Base_Column_List"/>
		from cell_info
		<where>
			<foreach collection="coverage" item="item" index="index" open="and objectid in(" separator="," close=")">
				#{item}
			</foreach>
		</where>
	</select>
 

mapper程式碼如下：

List<Cell_info> selectByMr(Map<String, Object> map);

@Override
	public List<Cell_info> searchWeakCoverage(Map<String, Object> map,Page page) {
		List<Cell_info> cellList = null;
		
		Map<String, Object> mapL = new HashMap<String, Object>();
		List<String>  list = complaintsAnalysisDao.searchWeakCoverage(map);//查詢多條結果，當做查詢條件
		if(0!=list.size()){
			mapL.put("coverage", list);
			mapL.put("page", page);//分頁用的
			cellList = cellInfoDao.selectByMr(mapL);
		}
		return cellList;
	}
