Title: TJSONObject : Whether objects can be directly transferred to json
Post by: Jzhen on February 09, 2023, 10:04:58 am

   Student student = new Student();
   student.setId(1);
   student.setAge("20");
   student.setName("jno");
   System.out.println(JSON.toJSON(student));
 
   String stuString = JSONObject.toJSONString(student);

jsonObject.ToString or jsonObject.ToJSON cannot implement such conversion. What should i do?

This is a record. Can it be implemented without changing the data type? I think it needs to inherit TPersistent. This modification may not be accepted by the company.
