将ResultSet转为List

public static List resultSetToList(ResultSet rs) throws java.sql.SQLException {   

           if (rs == null)   

               return Collections.EMPTY_LIST;   

           ResultSetMetaData md = rs.getMetaData(); //得到结果集(rs)的结构信息,比如字段数、字段名等   

           int columnCount = md.getColumnCount(); //返回此 ResultSet 对象中的列数   

           List list = new ArrayList();   

           Map rowData = new HashMap();   

           while (rs.next()) {   

            rowData = new HashMap(columnCount);   

            for (int i = 1; i <= columnCount; i++) {   

                    rowData.put(md.getColumnName(i), rs.getObject(i));   

            }   

            list.add(rowData);   

            System.out.println("list:" + list.toString());   

           }   

           return list;   

   }

接着在其他方法里处理返回的List

List ls = resultSetToList(rs);   

Iterator it = ls.iterator();   

while(it.hasNext()) {   

    Map hm = (Map)it.next();   

    System.out.println(hm.get("字段名大写"));   

}
