Show elements updated in real-time with Spring
0
God afternoon.
I am developing an app which show the places avalaible. In the case of Backend, researched about the SSE (Server-Sent-Event) and TailableCursors with MongoDB. I have done in Spring:
@Repository
public interface Repositorio extends ReactiveMongoRepository<Prueba, String> {
@Tailable
Flux<Prueba> findWithTailableCursorBy();
}
And the controller:
@RestController
@CrossOrigin
@RequestMapping
public class Controlador {
@Autowired
Repositorio repo;
@GetMapping(value = "/prueba", produces = MediaType.TEXT_EVENT_STREAM_VALUE)
public Flux<Prueba> getTodos() {
return repo.findWithTailableCursorBy();
}
@GetMapping("/prueba2")
public Flux<Prueba> prueba() {
return repo.findAll();
}
@PostMapping("/prueba")
public Mono<Prueba> insert(@RequestBody Prueba prueba) {
return repo.save(prueba);
}
}
The items don't change when updated. I thought that with Tailable Cursors I would solve it. However, I see that no...
Is there any way to show the rafters in real time with Spring? So I'm using EventSource on the client-side.
PS: The class model (a capped collection) is:
@Document(collection = "pruebas")
// Lombok's annotations
@Data @NoArgsConstructor @AllArgsConstructor
@EqualsAndHashCode @ToString
public class Prueba {
@Id private String id;
private String nombre;
private boolean activo = false;
}

I'm thinking here that "tailable cursors" are not really what you want here. These are actually special things which require "capped collections" in order to work. Modern API and server versions support "change streams" which is probably more like what you are looking for. Note that neither of these "mirrors a collection" if that is what you were expecting.
