Question

我正在尝试在Spring Boot 1.4中执行单元测试来测试我的验证在无效的查询字符串参数上返回400.

控制器

@RestController
@Validated
public class ExampleController {

    ...

    @RequestMapping(value = "/example", method = GET)
    public Response getExample(
            @RequestParam(value = "userId", required = true) @Valid @Pattern(regexp = MY_REGEX) String segmentsRequest {

        // Stuff here
    }

}

异常处理程序

@ControllerAdvice
@Component
public class GlobalExceptionHandler {

    private static final Logger logger = LoggerFactory.getLogger(GlobalExceptionHandler.class);

    // 400 - Bad Request
    @ExceptionHandler(value = {ConstraintViolationException.class})
    @ResponseStatus(HttpStatus.BAD_REQUEST)
    public void constrainViolationHandle(HttpServletRequest request, ConstraintViolationException exception) {
        logger.error("Error Bad Request (400)");
    }

}

上下文

@Bean
public Validator validator() {
    final ValidatorFactory validatorFactory = Validation.byDefaultProvider()
            .configure()
            .parameterNameProvider(new ReflectionParameterNameProvider())
            .buildValidatorFactory();
    return validatorFactory.getValidator();
}

@Bean
public MethodValidationPostProcessor methodValidationPostProcessor() {
    final MethodValidationPostProcessor methodValidationPostProcessor = new MethodValidationPostProcessor();
    methodValidationPostProcessor.setValidator(validator());
    return methodValidationPostProcessor;
}

单元测试

@RunWith(SpringRunner.class)
@WebMvcTest(ExampleController.class)
public class ExampleControllerTest {

    private static final String EMPTY = "";

    @Autowired
    private MockMvc mvc;

    @Test
    public void test() throws Exception {

        // Perform Request
        ResultActions response = this.mvc.perform(
            get("/example").param("userId", "invalid")
        );

        // Assert Result
        response.andExpect(status().isBadRequest())
                .andExpect(content().string(EMPTY));
    }

}

但是，当我运行测试时，我得到200而不是400。当我作为应用程序运行时，不执行验证。

我认为可能是因为它在执行测试时没有拿起两个验证bean？此验证有效

您正在使用的

@WebMvcTest注释是在所谓的独立MockMvc配置之上的Spring Boot包装器。这个MockMvc功能测试独立控制器，没有任何其他bean。

为了能够测试更广泛的网络配置，您需要使用web application setup：

@RunWith(SpringRunner.class)
@WebAppConfiguration
@ContextConfiguration("my-servlet-context.xml")
public class MyWebTests {

    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

    @Before
    public void setup() {
        this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    // ...

}

但请注意，此类Web应用程序设置并未提取所有Bean。例如，您需要显式注册Servler过滤器或Spring Security。但我认为应该包括验证。
