使用spring中的Rowmapper .

RowMapper能夠將數據中的每一行封裝成用戶定義的類，在數據庫查詢中，若是返回的類型是用戶自定義的類型則須要包裝.

       eg:   如下例子便可說明，能夠在mapRow方法中實現數據封裝，並返回本身所須要的類型。

List users = (List) getJdbcTemplate().query("SELECT * FROM " + SchemaUtil.getCMSSchema() + Constants.S_USER, smartUserMapper);

List users = (List) getJdbcTemplate().query("SELECT * FROM " + SchemaUtil.getCMSSchema() + Constants.S_USER, smartUserMapper);

private RowMapper smartUserMapper = new RowMapper() {
    public Object mapRow(ResultSet rs, int rowNum) throws SQLException {
        User user = new User();
        user.setSUserId(rs.getInt(Constants.SMART_USER_ID));
        user.setCreated(rs.getDate("CREATED"));
        user.setDescription(rs.getString("DESCRIPTION"));
        user.setEmailAddr(rs.getString("EMAIL_ADDR"));
        user.setImsi(rs.getString("IMSI"));
        user.setIpAddr(rs.getString("IP_ADDR"));
        user.setIsactive(rs.getString("ISACTIVE"));
        user.setName(rs.getString("NAME"));
        user.setPassword(rs.getString("PASSWORD"));
        user.setTelephoneNum(rs.getString("TELEPHONE_NUM"));
        user.setWvpdn(rs.getString("WVPDN"));
        user.setCommunityCode(rs.getString("COMMUNITY_CODE"));
        return user;
    }
};
