Jackson注释覆盖父类中的注释

问题描述

我希望我的所有对象都有一个ID，我希望将其序列化为某些子类，但不能用于其他一些

I would like all my objects to have an ID and I wish to serialise it for some child class but not for some others

例如：

public class A {
  protected Long id;
  ..getter and setter
}

public class B extends A {

  @Override
  @JsonIgnore
  public Long getId() {..}

  @Override
  @JsonIgnore
  public void setId(Long id) {..}

}

public class C extends B {

  @Override
  @JsonInclude
  public Long getId() {..}

  @Override
  @JsonInclude
  public void setId(Long id) {..}
}

public class Test {

  Set<C> tests ...
  ..getter setter
}

我试过序列化测试，但JSON字符串不包含ID
如果我从B中删除JsonIgnore，那么在那种情况下，Ids就在那里。

I have tried serialising Test but the JSON string doesn't include the IDsIf I remove the JsonIgnore from B then in that case the Ids are there.

有没有办法与杰克逊存档这个？

Is there a way with jackson to archive this?

推荐答案

使用

@JsonIgnore(false)

而不是

@JsonInclude
