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;            }                                                                                    });      }

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;}
