如何使用 WebFlux 和 ReactiveMongoRepository 保存元素?

How to save an element with WebFlux and ReactiveMongoRepository?

我想写第一个程序webFluxReactiveMongoRepository。 我有存储库:

@Repository
public interface personRepository extends ReactiveMongoRepository<Person,String> {
        Mono<Person> save(Person person);
}

我的服务:

@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);
    }

}

以及其余服务本身:

@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);
    }
}

现在,当我想测试服务并通过 postman 保存或查找所有人时,出现错误:

"path": "/all",
"status": 405,
"error": "Method Not Allowed",

也就是我理解的,请求连函数都没有到达,直接就报错了,这里哪里会报错?

问题似乎出在 saveOrUpdate() 方法中。您实际上并不需要 CompletableFuture(在这种情况下为什么需要?)并且以下内容应该有效:

@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);
    }
}
