Convert Json Rest to Java DTO

Question

is there a way that I can take the DTO's from a REST api? I want to create my DTO's automaticaly from the JSON REST api. Is there some way?

Answer 1

You can try use a framework library like RESTEasy (Jboss Suite) or Jersey or Gson

Then you only need define a estructure same a you class for example, if your class is something like:

@Entity
@Table(name = "\"entityName\"")
public class Entity implements Serializable {
    private static final long serialVersionUID = 3469107762875646075L;

    @Id
    private Integer id;

    @Column
    private String name;

    public Entity() {
    }

    //getters and setters

---

The interface will receive an object of that type.

@POST
@Path("/create")
@Produces(MediaType.APPLICATION_JSON)
Response createEntity(Entity entityObject);

---

And JSON be this way, then the conversion is automatic.

{
"id":"99",
"name":"stackoverflow"
}

NOTE: The information received must be of the same type defined in your Class to perform this conversion.
