How to save an element with WebFlux and ReactiveMongoRepository? - spring

Question

I want to write the first program webFlux and ReactiveMongoRepository.
i have repository:
#Repository
public interface personRepository extends ReactiveMongoRepository<Person,String> {
Mono<Person> save(Person person);
}
my service:
#AllArgsConstructor
#Service
public class personServiceImpl implements personService{
personRepository repository;
#Override
public Flux<Person> findAll() {
return repository.findAll();
}
#Override
public Mono<Person> saveOrUpdate(Person person) {
CompletableFuture<Person> future = CompletableFuture.supplyAsync(() -> {
repository.save(person);
return person;
});
return Mono.fromFuture(future);
}
}
and the rest service itself:
#RestController
#AllArgsConstructor
public class personController {
personServiceImpl personService;
#GetMapping("/all")
Flux<Person> getAllPerson(){
return personService.findAll();
}
#PostMapping("/save")
public Mono<Person> post(#RequestBody Person user) {
System.out.println("inside***************");
return personService.saveOrUpdate(user);
}
}
Now when I want to test the service and save or find everyone via postman, then I get an error:
"path": "/all",
"status": 405,
"error": "Method Not Allowed",
That is, as I understand it, the request does not even reach the function, but an error is immediately thrown, where can there be an error here?

Answer 1

The issue seems to be in saveOrUpdate() method. You don't actually need the CompletableFuture (why would you in this case?) and the following should work:
#AllArgsConstructor
#Service
public class personServiceImpl implements personService{
personRepository repository;
#Override
public Flux<Person> findAll() {
return repository.findAll();
}
#Override
public Mono<Person> saveOrUpdate(Person person) {
return repository.save(person);
}
}
