我有两个POJO，看起来像：

public ResponseA {
  private HeavyObject object;
  private AdditionalDataA additionalData;

  public ResponseA(HeavyObject object, AdditionalDataA additionalData) {
    this.object = object;
    this.additionalData = additionalData;
  }
}

个字符
然后我有一个方法，将这些对象发送到不同的端点，类似于：

public void sendResponses(
      ObjectMapper mapper, 
      HeavyObject object, 
      AdditionalDataA addDataA, 
      AdditionalDataB addDataB) {

    // Here object is serialized twice, which is costly!
    String jsonA = mapper.writeValueAsString(new ResponseA(object, addDataA));
    String jsonB = mapper.writeValueAsString(new ResponseB(object, addDataB));
    sendResponseA(jsonA);
    sendResponseB(jsonB);
}

型
有没有一种方法可以序列化这些响应，使HeavyObject只序列化一次？
