封装Spring-RowMapper,使得使用更加灵活

import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.HashMap;
import java.util.Map;

import org.springframework.jdbc.core.RowMapper;

public class MapRowMapper implements RowMapper<Map<String, Object>> {

	private String[] columns;

	public MapRowMapper(String[] columns) {
		this.columns = columns;
	}

	@Override
	public Map<String, Object> mapRow(ResultSet rs, int rowNum) throws SQLException {
		Map<String, Object> resultMap = new HashMap<String, Object>();
		if (columns != null && columns.length > 0) {
			if (columns.length > 0) {
				for (String col : columns) {
					resultMap.put(col, rs.getObject(col));
				}
			}
		}
		return resultMap;
	}

}

测试代码Demo

	public List<Map<String, Object>> queryMapData(){
		String tableNames[] = { "TSDEV.FX_DL_DTL_EMGY",
	    						"TSDEV.DL_MEM_FLD_NM",
	    						"TSDEV.DL_ADJ_MEM_FLD_NM"};
		Object obj[] = {"uuasroot"};
		String columns[] = {"floorName", "productCode", "userCode", "statu"};
		StringBuffer sb = new StringBuffer();
		sb.append("SELECT T.FLD_NM as floorName ,T.PRDCT_CD as productCode ,T.USR_CD as userCode ,N.ST as statu FROM TSDEV.DL_MEM_FLD_NM T, TSDEV.DL_ADJ_MEM_FLD_NM N WHERE T.PRDCT_CD  = N.PRDCT_CD AND N.USR_CD = ?");
		TsJdbcTemplate jt = TsJdbcSingletonProvider.get().getTsJdbcTemplateByTable(DealMgmtHelper.PLUGIN_ID, tableNames);
		return jt.query(sb.toString(), obj, new MapRowMapper(columns));
//		return jt.query(sb.toString(), obj, new BeanPropertyRowMapper<ParamVO>(ParamVO.class));  spring-framework 使用
