Spring JPA row_to_json PostgreSQL

Question

是否可以使用列名获取查询结果，而不是使用列注释创建实体？像：

@Query(value = "select emp.emp_id, emp_fname, emp_lname, emp_division_id, emp_role_id," +
        "(select count(*) from cheers.ch_kudos where kudos_receiver_id = emp.emp_id) as received_kudos_num, " +
        "(select count(*) from cheers.ch_kudos where kudos_sender_id = emp.emp_id) as sent_kudos_num " +
        "from cheers.ch_employee as emp where emp.emp_active_flag =  'true'", 
        nativeQuery=true)   
List<Object> getAllEmployeesReport();

返回结果只有值，但没有列名。

否则，有没有办法通过Spring JPA获得PostgreSQL row_to_json的结果？

@Query(value = "select row_to_json(t) from (select emp.emp_id, emp_fname, emp_lname, emp_division_id, emp_role_id," +
        "(select count(*) from cheers.ch_kudos where kudos_receiver_id = emp.emp_id) as received_kudos_num, " +
        "(select count(*) from cheers.ch_kudos where kudos_sender_id = emp.emp_id) as sent_kudos_num " +
        "from cheers.ch_employee as emp where emp.emp_active_flag =  'true') t", 
        nativeQuery=true)   
List<Object> getAllEmployeesReport();

它将抛出JDBC 111异常。
