Spring Boot 使用包含自动连接属性的ControllerAdvice进行WebMvc测试

考虑到下面的代码是最新版本的SpringBoot应用程序的一部分,在一些项目中,测试结果是无法启动应用程序,因为它未能将ErrorMessages注入ControllerAdvice。但由于某些原因,在其他项目中,此代码通过。我在配置、gradle-build或注解方面没有任何差异,所以不完全确定我是否发现了bug。是否有任何方法可以影响在@WebMvcTest上读取和注入的ErrorMessages?
控制器上的控制器文件夹

@RestController
@Api(value = "Some Service", tags = "Some Service")
public class SomeController {

    @Autowired
    SomeService someService;

    @ApiOperation(value = "Gets something")
    @ApiResponses(value = {
            @ApiResponse(code = 200, message = "OK"),
            @ApiResponse(code = 500, message = "Internal server error", response = ErrorResponse.class) })
    @GetMapping(value = "/something", produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<SomeResponse> getSomething(
            @AuthenticationPrincipal CustomOAuth2Authentication authentication,
    ) throws ApiException {
        return ResponseEntity.ok(someService.get());
    }
}

异常文件夹上的控制器建议

@Order(Ordered.HIGHEST_PRECEDENCE)
@ControllerAdvice
public class GlobalExceptionHandler {

    @Autowired
    private ErrorMessages errorMessages;

    @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR)
    @ExceptionHandler(Throwable.class)
    @ResponseBody
    public ErrorResponse handler(HttpServletRequest request, final Throwable ex) 
    {
        log.error("Unexpected error", ex);
        return new ErrorResponseBuilder().with(it -> {
            it.status = ErrorCodes.INTERNAL_SERVER_EXCEPTION;
            it.error = ex.getLocalizedMessage();
            it.exception = ex.getClass().getName();
            it.messages = Collections.singletonList(errorMessages.internalServerException);
            it.path = request.getRequestURI();
        }).build();
    }
}

errorMessages on Exception文件夹(从Spring Cloud读取)

@Component
public class ErrorMessages {

    @Value("${"+ErrorCodes.INTERNAL_SERVER_EXCEPTION +"}")
    public String internalServerException;

}

异常文件夹上的错误代码

public class ErrorCodes {
    private ErrorCodes() {}

    public static final String INTERNAL_SERVER_EXCEPTION = "3031";
}

测试文件夹上的TestClass

@RunWith(SpringRunner.class)
@WebMvcTest(controllers = SomeController.class)
@ActiveProfiles("test")
@ContextConfiguration(classes = {ErrorMessages.class, 
GlobalExceptionHandler.class})
public class SomeControllerTest {

    private String SERVICE_URL = "/some";

    @Autowired
    private MockMvc mockMvc;

    @Autowired
    private WebApplicationContext wac;

    @Before
    public void setup() throws ApiException {

        this.mockMvc = MockMvcBuilders
                .webAppContextSetup(this.wac)
                .apply(SecurityMockMvcConfigurers.springSecurity())
                .build();
    }

    @Autowired
    ErrorMessages errorMessages;

    @MockBean
    private SomeService someService;

    @Autowired
    @InjectMocks
    private SomeController someController;

    @Test
    @WithMockCustomUser()
    public void getCheckout_Exception() throws Exception {
        ApiException e = new ApiException("code123", "message123");
        when(someService.get(anyString(), anyInt())).thenThrow(e);
        mockMvc.perform(get(SERVICE_URL))
            .andExpect( status().is( equalTo( 
               HttpStatus.INTERNAL_SERVER_ERROR.value())))
            .andExpect( content().string(containsString(e.getClass().getName())))
            .andExpect( content().string(containsString(e.getCode())))
            .andExpect( content().string(containsString(e.getMessage())))
            .andExpect( content().string(containsString(errorMessages.transformingException)));
    }
}

错误是

您可以尝试在测试类中导入异常处理程序:

@RestController
@Api(value = "Some Service", tags = "Some Service")
@Import(GlobalExceptionHandler.class)  // EXCEPTION HANDLER CLASS
public class SomeController {
e5njpo68

e5njpo682#

错误的根本原因是您正在使用@WebMvcTest。此注解仅加载使用@Controller,@RestController,@ControllerAdvice注解的bean。它跳过所有其他带注解的SpringBean(例如@component、@service和其他)
我猜你的bean“ErrorMessage”是用这些被排除的注解之一注解的,你会得到下面的错误:通过字段“errorMessages”表示的不满足的依赖关系
解决方案:您可以使用@SpringBootTest而不是@WebMvcTest。唯一的缺点是springboottest将加载所有的springbean,因此速度较慢。
如果你有任何不使用“ErrorMessage”依赖项的选项,那么这个错误本身就会消失。注意:ErrorMessage似乎是数据,无论如何都不应该自动连接,因为spring bean默认情况下是单例的,因此可能会导致其他功能问题。
