Resource and ControllerLinkBuilder not found and deprecated

Question

I am using Spring Boot 2.2.0.M1 with HATEOAS and Gradle.

implementation 'org.springframework.boot:spring-boot-starter-hateoas'

Right now, Resource is not found by the IDE (IntelliJ IDEA 2018.3) and ControllerLinkBuilder is marked as deprecated.

package com.example.restfulwebservicegradle.user;

import static org.springframework.hateoas.server.mvc.ControllerLinkBuilder.linkTo;
import static org.springframework.hateoas.server.mvc.WebMvcLinkBuilder.methodOn;

import com.example.restfulwebservicegradle.User;
import com.example.restfulwebservicegradle.UserDaoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.hateoas.server.mvc.ControllerLinkBuilder;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.servlet.support.ServletUriComponentsBuilder;

import javax.validation.Valid;
import java.net.URI;
import java.util.List;

@RestController
public class UserResource {

    @Autowired
    private UserDaoService service;

    @GetMapping("users/{id}")
    public Resource<User> retrieveUser(@PathVariable int id) {
        User user = service.findOne(id);

        if (user == null)
            throw new UserNotFoundException("id-" + id);


        // Resource not found
        Resource<User> resource = new Resource<User>(user);

        // Deprecated
        ControllerLinkBuilder linkTo = linkTo(methodOn(this.getClass()).retrieveAllUsers());

        resource.add(linkTo.withRel("all-users"));

        return resource;
    }
}

The imports available according to the IDE are:

How can I solve this?

My goal is to found Resource from HATEOAS and to use the substitute of ControllerLinkBuilder.

Answer 1

The most fundamental change is the fact that Spring HATEOAS doesn’t create resources. That’s what Spring MVC/Spring WebFlux does. We create vendor neutral representations of hypermedia. So we renamed those core types:

1. ResourceSupport is now RepresentationModel
2. Resource is now EntityModel
3. Resources is now CollectionModel
4. PagedResources is now PagedModel
