NewsResource

The NewsResource class is essential, this endpoint enables users to review news previously registered, and it also provides an endpoint to return the updated news. This is an important feature because we are interested only in the relevant news. Irrelevant news cannot be shown on the portal. The resource class should look like this:

package springfive.cms.domain.resources;

import java.util.Arrays;
import java.util.List;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestController;
import springfive.cms.domain.models.News;
import springfive.cms.domain.models.Review;
import springfive.cms.domain.vo.NewsRequest;

@RestController
@RequestMapping("/api/news")
public class NewsResource {

  @GetMapping(value = "/{id}")
  public ResponseEntity<News> findOne(@PathVariable("id") String id){
    return ResponseEntity.ok(new News());
  }

  @GetMapping
  public ResponseEntity<List<News>> findAll(){
    return ResponseEntity.ok(Arrays.asList(new News(),new News()));
  }

  @PostMapping
  public ResponseEntity<News> newNews(NewsRequest news){
    return new ResponseEntity<>(new News(), HttpStatus.CREATED);
  }

  @DeleteMapping("/{id}")
  @ResponseStatus(HttpStatus.NO_CONTENT)
  public void removeNews(@PathVariable("id") String id){
  }

  @PutMapping("/{id}")
  public ResponseEntity<News> updateNews(@PathVariable("id") String id,NewsRequest news){
    return new ResponseEntity<>(new News(), HttpStatus.OK);
  }

  @GetMapping(value = "/{id}/review/{userId}")
  public ResponseEntity<Review> review(@PathVariable("id") String id,@PathVariable("userId") String userId){
    return ResponseEntity.ok(new Review());
  }

  @GetMapping(value = "/revised")
  public ResponseEntity<List<News>> revisedNews(){
    return ResponseEntity.ok(Arrays.asList(new News(),new News()));
  }

}

The NewsRequest class can be found at GitHub.

Pay attention to the HTTP verbs and the HTTP status code, as we need to follow the correct semantics.
