How to map POJO to several JSON presentation

Question

How to map POJO to several JSON presentation?

I am using Jackson.

I want something like code below

@JsonIgnorePropertiesStreamA({ \"value2\"         


        

Answer 1

You use JSON Views

class Views {
    static class PublicView { }
    static class StreamA extends PublicView { }
    static class OtherWay extends PublicView { }
}

public class Value {
    @JsonView(Views.PublicView.class) public int value;
    @JsonView(Views.OtherWay.class) public int value2;
    @JsonView(Views.StreamA.class) public int value3;
}


String json = new ObjectMapper()
              .writerWithView(Views.OtherWay.class)
              .writeValueAsString(valueInstance);

Note that these are inclusive rather than exclusive; you create a view that includes the fields you want.
