spring DAO中批处理的运用

spring DAO中批处理的使用
批处理对大量数据的insert或着udpate有着时间上的优越性
看代码
这个主要用的是回调

 public void insertPropSluiceLogList(final List<PropSluiceLog> propSluiceLogList) {
        getSqlMapClientTemplate().execute(new SqlMapClientCallback() {                   
            public Object doInSqlMapClient(SqlMapExecutor executor) throws SQLException {
             executor.startBatch();
             for(PropSluiceLog propSluiceLog : propSluiceLogList){
                 executor.insert("T_PROP_SLUICE_LOG.insertPropSluiceLog", propSluiceLog);   
             }
             executor.executeBatch();   
             return null;
            }                                                                            
        });  
    }

这个主要是要用事物

public List<HotelInfo> findHotelInfoFogPaginatedList(HotelSearchVO hotelSearchVO,int fromPage,int toPage) {
		
		List<HotelInfo> list = new ArrayList<HotelInfo>();
		List<String> props = new ArrayList<String>();
		props = hotelSearchVO.getProps();
		SqlMapClient sqlMapClient = this.getSqlMapClient();
		Map map = new HashMap();
		map.put("hotelSearchVO", hotelSearchVO);
		map.put("row_from", fromPage);
		map.put("row_to", toPage);
		map.put("tp_flag", "1");
		try{
			sqlMapClient.startTransaction();
			sqlMapClient.startBatch();
			for(int i = 0 ; i < props.size(); i ++){
				String propId = props.get(i);
				sqlMapClient.insert("Prop.insertTpPropid",propId);
			}
			sqlMapClient.executeBatch();
			list = sqlMapClient.queryForList("Prop.findHotelInfoAll", map);
			sqlMapClient.endTransaction();
		}catch(Exception e){
			logger.info("class name TPDAO--method findHotelInfoFogPaginatedList error!"+e);
		}
		
		return list;
	}
