Dropwizard阅读请求JSON

Question

I'm sending a very simple POST request with a JSON body of just "id":"string". I get the following in response when I send my post:

{
    "id": "robert"
}

-

{
    "code": 400,
    "message": "Unable to process JSON"
}

-

@Path("/myapp/user")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class UserHandler {

    @POST
    public void doPost(Entity e) {
        System.out.println(e.id);
    }

    public class Entity {
        @JsonProperty String id;
    }
}

Answer 1

I was missing the @JsonProperty identifier... this fixed it:

public class Entity {
    @JsonProperty("id") String id;
}
