I have polymorphic types and serialization when the type parameter is
passed in JSON works fine.
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;import
com.fasterxml.jackson.annotation.JsonSubTypes;import
com.fasterxml.jackson.annotation.JsonTypeInfo;
@JsonIgnoreProperties(ignoreUnknown = true)@JsonTypeInfo(use =
JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.EXISTING_PROPERTY, property =
"type", defaultImpl = Dog.class)@JsonSubTypes({
@JsonSubTypes.Type(value=Dog.class, name="dog"),
@JsonSubTypes.Type(value=Cat.class, name="cat")}) public class Animal {
... }
public class Dog extends Animal { ... }public class Cat extends Animal { ... }
{"name":"Tom", type="cat"} // this works as expected
@POST@Produces(MediaType.APPLICATION_JSON)public Response animal(Animal animal)
{...}
But, if I directly want to get a subtype object without passing type it
does not work.
@POST@Produces(MediaType.APPLICATION_JSON)public Response dog(Dog dog) {...}
{"name":"Tom"} // this wont work
Missing type id when trying to resolve subtype of [simple type, class
....Dog]: missing type id property 'type'
Any way to achieve this?
