REST API and its design principles

Comment

Principles of Rest API

Client-Server decoupling. In a REST API design, client and server programs must be independent. ...

Uniform Interface. All API queries for the same resource should look the same regardless of where they come from. ...

Statelessness. ...

Layered System architecture. ...

Cacheable. ...

Code on Demand. ...

GET. ...

POST.

HATEOAS

@RestController
@RequestMapping("/users/{id}/albums")
public class AlbumsController {
    
    @Autowired
    AlbumsService albumsService;
    Logger logger = LoggerFactory.getLogger(this.getClass());
    @GetMapping( 
            produces = { 
                MediaType.APPLICATION_JSON_VALUE,
                MediaType.APPLICATION_XML_VALUE,
            })
    public List<AlbumResponseModel> userAlbums(@PathVariable String id) {

        List<AlbumResponseModel> returnValue = new ArrayList<>();
        
        List<AlbumEntity> albumsEntities = albumsService.getAlbums(id);
        
        if(albumsEntities == null || albumsEntities.isEmpty())
        {
            return returnValue;
        }
        
        Type listType = new TypeToken<List<AlbumResponseModel>>(){}.getType();
 
        returnValue = new ModelMapper().map(albumsEntities, listType);
        logger.info("Returning " + returnValue.size() + " albums");
        return returnValue;
    }
}
