How do I restrict Keys when posting JSON?

[taisuke-tomida]

I would like to create a class and put restrictions on JSON keys, like Spring Boot Framework.
↓

import java.util.Date;

public class OutputData {
	public int id;
	public String value;
	public Date date;
}

If the above class is prepared, the JSON to be posted will be as follows.

{
    "id":123,
    "value":"InputData.Value",
    "date":"2020-09-28T06:45:30.925+00:00"
}

Incorrect JSON keys will result in an error.
