使用WebTestClient和ControllerAdvice

我正在尝试对我的控制器和特定情况进行单元测试:我的服务返回一个Mono.Empty,我抛出一个NotFoundException,我不想确保我得到一个404异常

这是我的控制器:

@GetMapping(path = "/{id}")
    public Mono<MyObject<JsonNode>> getFragmentById(@PathVariable(value = "id") String id) throws NotFoundException {

        return this.myService.getObject(id, JsonNode.class).switchIfEmpty(Mono.error(new NotFoundException()));

    }

这是我的控制器建议:

@ControllerAdvice
public class RestResponseEntityExceptionHandler {

    @ExceptionHandler(value = { NotFoundException.class })
    protected ResponseEntity<String> handleNotFound(SaveActionException ex, WebRequest request) {
        String bodyOfResponse = "This should be application specific";
        return ResponseEntity.status(HttpStatus.NOT_FOUND).body("Resource not found");
    }

}

和我的测试:

@Before
    public void setup() {
        client = WebTestClient.bindToController(new MyController()).controllerAdvice(new RestResponseEntityExceptionHandler()).build();
    }
@Test
    public void assert_404() throws Exception {

        when(myService.getobject("id", JsonNode.class)).thenReturn(Mono.empty());

        WebTestClient.ResponseSpec response = client.get().uri("/api/object/id").exchange();
        response.expectStatus().isEqualTo(404);

    }

我得到一个NotFoundException但是500错误而不是404这意味着我的建议没有被称为

堆栈跟踪:

java.lang.AssertionError: Status expected:<404> but was:<500>

> GET /api/fragments/idFragment
> WebTestClient-Request-Id: [1]

任何想法?

我相信您可以删除此控制器建议,只需拥有以下内容:

    @GetMapping(path = "/{id}")
    public Mono<MyObject<JsonNode>> getFragmentById(@PathVariable(value = "id") String id) {

        return this.myService.getObject(id, JsonNode.class)
                             .switchIfEmpty(Mono.error(new ResponseStatusException(HttpStatus.NOT_FOUND)));

    }

至于ResponseEntityExceptionHandler,这个类是Spring MVC的一部分,所以我认为你不应该在WebFlux应用程序中使用它。
