Resultset 轉化成list或map


public static List<Map<String, Object>> convertList(ResultSet rs) {
    List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
    try {
        ResultSetMetaData md = rs.getMetaData();
        int columnCount = md.getColumnCount();
        while (rs.next()) {
            Map<String, Object> rowData = new HashMap<String, Object>();
            for (int i = 1; i <= columnCount; i++) {
                rowData.put(md.getColumnName(i), rs.getObject(i));
            }
            list.add(rowData);
        }
    } catch (SQLException e) {
    // TODO Auto-generated catch block
        e.printStackTrace();
    } finally {
        try {
            if (rs != null)
            rs.close();
            rs = null;
        } catch (SQLException e) {
            e.printStackTrace();
    }
}
    return list;
}


public static Map<String, Object> convertMap(ResultSet rs){
    Map<String, Object> map = new TreeMap<String, Object>();
    try{
        ResultSetMetaData md = rs.getMetaData();
        int columnCount = md.getColumnCount();
        while (rs.next()) {
            for (int i = 1; i <= columnCount; i++) {
                map.put(md.getColumnName(i), rs.getObject(i));
            }
        }
