[英]Spring MVC Controllers Unit Test not calling @ControllerAdvice
[英]unit test spring controller with WebTestClient and ControllerAdvice
我正在嘗試對我的控制器和特定情況進行單元測試:我的服務返回一個Mono.Empty,我拋出一個NotFoundException,我不想確保我得到一個404異常
這是我的控制器:
@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()));
}
這是我的控制器建議:
@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");
}
}
和我的測試:
@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);
}
我得到一個NotFoundException但是500錯誤而不是404這意味着我的建議還沒有被調用
堆棧跟蹤 :
java.lang.AssertionError: Status expected:<404> but was:<500>
> GET /api/fragments/idFragment
> WebTestClient-Request-Id: [1]
No content
< 500 Internal Server Error
< Content-Type: [application/json;charset=UTF-8]
Content not available yet
任何的想法 ?
我相信你可以刪除這個控制器的建議,只需要有以下內容:
@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)));
}
至於ResponseEntityExceptionHandler
,這個類是Spring MVC的一部分,所以我認為你不應該在WebFlux應用程序中使用它。
