How can i make this work ? I look at the other questions but i cant figure it out how. Actually i dont know much about jackson. Maybe the "lombok" is cause the problem. thank you in advance.

    @Data class A{String b;}
    @Data class B<T>{ T c; }


    A a1 = new A();
    a1.setB("sa");
    B<A> s = new B<A>();
    s.c = a1;

    ObjectMapper objectMapper = new ObjectMapper();

    String sj = objectMapper.writeValueAsString(s);
    System.out.println(sj); // {"c":{"b":"sa"}} 

    B<A> ba = objectMapper.readerFor(new TypeReference<B<A>>() {
    })
            .readValue(sj); // this is not working

Gives this error:

    com.fasterxml.jackson.databind.JsonMappingException: Cannot deserialize 
    EmbeddedTest$1B (of type local/anonymous) as a Bean.

Which Lombok annotation you have used. I have also used Jackson for deserializing having lombok @Data annotation. – Gaurav Srivastav May 25 '18 at 17:58
@Data will generate methods so nothing serialization related. – Antoniossss May 25 '18 at 18:02
Just @Data i have used. – osese May 25 '18 at 18:14
