try (Connection conn = dataSource.getConnection();
			PreparedStatement preparedStatement = conn.prepareStatement(sqq)) {
		
			try (ResultSet rs = preparedStatement.executeQuery()) {
				while (rs.next()) {
					System.out.println(rs.getInt(1));
					System.out.println(rs.getInt(2));
				}
			}
		}

代码正常无错误

Sql sql = Sqls.create(sqq);
	    sql.setCallback(new SqlCallback() {
	        public Object invoke(Connection conn, ResultSet rs, Sql sql) throws SQLException {
	           // List<String> list = new LinkedList<String>();
	            while (rs.next())
	            	System.out.println(rs.getInt(1));
					System.out.println(rs.getInt(2));
	            return null;
	        }
	    });
	    dao.execute(sql);
	    

nutz回调就报错
