1.从数据库获取到的数据(没有办法一次性取回数据)

//搜索商店List
    
      searchShopVO = shopInfoMapper.searchShop(searchContent, type,locationId,orderType,pageNums,lastTime);//搜索服务List
     
       searchServiceVO = shopInfoMapper.searchService(searchContent, type, locationId, orderType, pageNums, lastTime);
     
    

//SearchShopVO类如下public class SearchShopVO {		private Integer shopId;	private String shopLogoUrl;	private String shopName;	private List
    
      shopServiceType;	private String totalScore;	private String address;	private String longitude;	private String latitude;	private String updTime;	private List
     
       shopService;//get set方法省略……}
     
    

工程需求： 1.合并searchShopVO与searchServiceVO，组成searchShopVO 2.searchShopVO去重，条件是shopId 3.返回searchShopVO即可 数据库请求回来的数据 searchShopVO={ 1000000003 1000000009 1000000008 1000000007 1000000006 1000000005 1000000004 1000000002 1000000001 1000000000 } searchServiceVO={ 1000000003 1000000004 1000000002 1000000001 1000000000

//1.合并到一个list中		searchShopVO.addAll(searchServiceVO);		//2.取出所有的shopId		List
    
      resultListInteger = new ArrayList
     
      ();		List
      
        resultListSearchShopVO = new ArrayList
       
        ();		for (int i = 0; i < searchShopVO.size(); i++) {			resultListInteger.add(searchShopVO.get(i).getShopId());		}		//3.shopId去重		List
        
          tempList= new ArrayList
         
          (); for (int i = 0; i < resultListInteger.size(); i++) { if (!tempList.contains(resultListInteger.get(i))) { tempList.add(resultListInteger.get(i)); resultListSearchShopVO.add(searchShopVO.get(i)); } }
         
        
       
      
     
    

最后返回的结果是resultListSearchShopVO
