ResultSet 转换成 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;
}
