JAX-RS 仅序列化少数属性

Question

We have a DTO like below

public class Student {
    private String name;
    private String id;
    private ExamResults results;
    private Address residentialAddress;
    private Address permanentAddress;
    // setter and getter methods
}

The same DTO is used by multiple endpoints like student/details/{studId}, student/details/{studId}/results

In student/details/{studId} endpoint we dont populate results property. But still it is being returned as null in the response.

Similarly, in student/details/{studId}/results we dont populate permanentAddress and residentialAddress , but still these are being returned as null in the response.

Basically, I would like to control what properties are serialized based on the endpoint irrespective of whether they are null or not.

Thanks.

You can try to use

@JsonInclude(JsonInclude.Include.NON_NULL)
public class Student {
