可以通过Annotation JSONType支持seeAlso配置。用法如下:
@JSONType(seeAlso={Dog.class, Cat.class})
public static class Animal {
}
@JSONType(typeName = "dog")
public static class Dog extends Animal {
public String dogName;
}
@JSONType(typeName = "cat")
public static class Cat extends Animal {
public String catName;
}
Dog dog = new Dog();
dog.dogName = "dog1001";
String text = JSON.toJSONString(dog, SerializerFeature.WriteClassName);
Assert.assertEquals("{\"@type\":\"dog\",\"dogName\":\"dog1001\"}", text);
Dog dog2 = (Dog) JSON.parseObject(text, Animal.class);
Assert.assertEquals(dog.dogName, dog2.dogName);
Cat cat = new Cat();
cat.catName = "cat2001";
String text = JSON.toJSONString(cat, SerializerFeature.WriteClassName);
Assert.assertEquals("{\"@type\":\"cat\",\"catName\":\"cat2001\"}", text);
Cat cat2 = (Cat) JSON.parseObject(text, Animal.class);
Assert.assertEquals(cat.catName, cat2.catName);
