您需要告诉序列化/反序列化如何绑定实现:

You need to tell the serialisation/deserialisation how to bind the implementation:

@JsonTypeInfo(
    use = JsonTypeInfo.Id.NAME, // Were binding by providing a name
    include = JsonTypeInfo.As.PROPERTY, // The name is provided in a property
    property = "type", // Property name is type

    @JsonSubTypes.Type(value = Lion.class, name = "Lion"),
    @JsonSubTypes.Type(value = Dog.class, name = "Dog")
})

public class Animal {
