泛型類轉換爲Json

public class MyClass<T>{
  private T result;
  
  @JsonCreator // 重要註解，指定反序列化的構造函數
  MyClass(@JsonProperty("result") T result){
    this.result = result;
  }
  
  public T getResult(){
    return this.result;
  }
}

ObjectMapper om = new ObjectMapper();
// 泛型實例化爲Class1
MyClas myClass1 = om.readValue(json, new TypeReference<MyClass<Class1>>(){});
// 泛型實例化爲Class2
MyClas myClass2 = om.readValue(json, new TypeReference<MyClass<Class2>>(){});
