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]
No content
< 500 Internal Server Error

任何想法?
答案 0 :(得分:2)
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。
