How to add custom deserializer to interface using jackson

Question

Saying I have an interface A, I want to use custom deserializer for all classes implement interface A, So I use code below but it doesn't work, While CustomAserializer works. So what should I do to deserialize all classes implement A using my custom deserializer. Thanks.

module.addDeserializer(A.class, new CustomADeserializer());
module.addSerializer(A.class, new CustomASerializer())

Just in case someone need a solution to serialize and desiralize inheritance hierarchy

you can use jackson annotation in more elegant way : JsonTypeInfo and JsonSubTypes

 @JsonTypeInfo(
  use = JsonTypeInfo.Id.NAME, 
  include = JsonTypeInfo.As.PROPERTY, 
  property = "type")
@JsonSubTypes({ 
  @Type(value = ServiceUser.class, name = "service"), 
  @Type(value = AdminUser.class, name = "admin") 
})
public interface User{
    // ...
}
