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
