Dropwizard resource classes calling another resource method classes?

问题

I was wondering if it was possible in dropwizard to call another resource method class from a different resource class.

I looked around other posts and using ResourceContext allows one to call a get method from another resource class, but it also possible to use a post method from another resource class.

Let say we have two resource classes A and B. In class A, I have created some JSON and I want to post that JSON to B class using B's post method. Would that be possible?

Yes, Resource Context can be used to access both POST and GET methods from another method in same or different resource.
With the help of @Context, you can easily access the methods.

@Path("a")
class A{
    @GET
    public Response getMethod(){
        return Response.ok().build();
    }
    @POST
    public Response postMethod(ExampleBean exampleBean){
        return Response.ok().build();
    }
}

You can now access the methods of Resource A from Resource B in the following manner.

@Path("b")
class B{
    @Context 
    private javax.ws.rs.container.ResourceContext rc;

    @GET
    public Response callMethod(){
        //Calling GET method
        Response response = rc.getResource(A.class).getMethod();

        //Initialize Bean or paramter you have to send in the POST method
        ExampleBean exampleBean = new ExampleBean();

        //Calling POST method
        Response response = rc.getResource(A.class).postMethod(exampleBean);

        return Response.ok(response).build();
    }
}
