@Spring REST控制器中有效Hibernate验证

Question

我试图在带有@valid注释的Spring REST控制器中使用Hibernate验证。

但验证没有发生。

下面是Maven构建必须要说的话：

java.lang.AssertionError：状态应为:<400>，但实际为:<201>

@Test
public void testValidation() throws Exception {
    HttpHeaders httpHeaders = Common.createAuthenticationHeaders("stephane" + ":" + PASSWORD);

MvcResult resultPost = this.mockMvc.perform(
        post("/admin").headers(httpHeaders)
        .contentType(MediaType.APPLICATION_JSON)
        .accept(MediaType.APPLICATION_JSON)
        .content("{ \"firstname\" : \"" + admin0.getFirstname() + "\", \"lastname\" : \"" + admin0.getLastname() + "\", \"email\" : \"" + admin0.getEmail() + "\", \"login\" : \"" + admin0.getLogin() + "\", \"password\" : \"" + admin0.getPassword() + "\", \"passwordSalt\" : \"" + admin0.getPasswordSalt() + "\" }")
    ).andDo(print())
    .andExpect(status().isBadRequest())
    .andExpect(jsonPath("$.firstname").value(admin0.getFirstname()))
    .andExpect(jsonPath("$.lastname").value(admin0.getLastname()))
    .andExpect(jsonPath("$.email").value(""))
    .andExpect(jsonPath("$.login").value("short"))
    .andExpect(jsonPath("$.password").value(admin0.getPassword()))
    .andExpect(jsonPath("$.passwordSalt").value(admin0.getPasswordSalt()))
    .andExpect(header().string("Location", Matchers.containsString("/admin/")))
    .andReturn();

@ControllerAdvice
public class AdminExceptionHandler {

    @ExceptionHandler(AdminNotFoundException.class)
    @ResponseBody
    public ResponseEntity<ErrorInfo> adminNotFoundException(HttpServletRequest request, AdminNotFoundException e) {
        String url = request.getRequestURL().toString();
        String errorMessage = localizeErrorMessage("error.admin.not.found", new Object[] { e.getAdminId() });
        return new ResponseEntity<ErrorInfo>(new ErrorInfo(url, errorMessage), HttpStatus.NOT_FOUND);
    }

    @ExceptionHandler(MethodArgumentNotValidException.class)
    @ResponseBody
    public ResponseEntity<ErrorFormInfo> methodArgumentNotValidException(HttpServletRequest request, MethodArgumentNotValidException e) {
        String url = request.getRequestURL().toString();
        String errorMessage = localizeErrorMessage("error.admin.invalid.form.argument");
        ErrorFormInfo errorFormInfo = new ErrorFormInfo(url, errorMessage);
        BindingResult result = e.getBindingResult();
        List<FieldError> fieldErrors = result.getFieldErrors();
        errorFormInfo.getFieldErrors().addAll(populateFieldErrors(fieldErrors));
        return new ResponseEntity<ErrorFormInfo>(errorFormInfo, HttpStatus.BAD_REQUEST);
    }

    public List<ErrorFormField> populateFieldErrors(List<FieldError> fieldErrorList) {
        List<ErrorFormField> errorFormFields = new ArrayList<ErrorFormField>();
        StringBuilder errorMessage = new StringBuilder("");
        for (FieldError fieldError : fieldErrorList) {
            errorMessage.append(fieldError.getCode()).append(".");
            errorMessage.append(fieldError.getObjectName()).append(".");
            errorMessage.append(fieldError.getField());
            errorFormFields.add(new ErrorFormField(fieldError.getField(), localizeErrorMessage(errorMessage.toString())));
            errorMessage.delete(0, errorMessage.capacity());
        }
        return errorFormFields;
    }

    private String localizeErrorMessage(String errorCode) {
        return localizeErrorMessage(errorCode, null);
    }

    private String localizeErrorMessage(String errorCode, Object args[]) {
        Locale locale = LocaleContextHolder.getLocale();
        String errorMessage = messageSource.getMessage(errorCode, args, locale);
        return errorMessage;
    }

}

注意AdminNotFoundException是由其他测试触发的。

但不触发MethodArgumentNotValidException。

下面是controller类：

@Controller
@ExposesResourceFor(Admin.class)
@RequestMapping("/admin")
public class AdminController {

    @RequestMapping(method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE, consumes = MediaType.APPLICATION_JSON_VALUE)
    @ResponseBody
    public ResponseEntity<Admin> add(@RequestBody @Valid Admin admin, UriComponentsBuilder builder) {
        AdminCreatedEvent adminCreatedEvent = adminService.add(new CreateAdminEvent(admin.toEventAdmin()));
        HttpHeaders responseHeaders = new HttpHeaders();
        responseHeaders.setLocation(builder.path("/admin/{id}").buildAndExpand(adminCreatedEvent.getAdminId()).toUri());
        Admin createdAdmin = adminResourceAssembler.toResource(adminCreatedEvent.getEventAdmin());
        ResponseEntity<Admin> responseEntity = new ResponseEntity<Admin>(createdAdmin, responseHeaders, HttpStatus.CREATED);
        return responseEntity;
    }

}

mvn clean install tomcat7:run -DskipTests

curl -H "Accept:application/json" --user joethebouncer:mignet http://localhost:8080/learnintouch-rest/admin -X POST -H "Content-Type: application/json" -H "Accept: application/json" -d "{ \"firstname\" : \"Stephane\", \"lastname\" : \"Eybert\", \"email\" : \"\", \"login\" : \"short\", \"password\" : \"mignet\", \"passwordSalt\" : \"7bc7bf5f94fef7c7106afe5c3a40a2\" }"

亲切的问候,

我尝试了您的代码，遵循了您提到的相同步骤，并且验证确实正确地发生了。

这是我使用与您发布的完全相同的curl命令得到的响应：

{“URL”：“http：//localhost:8080/learnintouch-rest/admin”，“message”：“管理表单参数无效。”，“fielderrors”：[{“fieldname”：“login”，“fielder ror”：“length.admin.login”}，{“fieldname”：“email”，“fielderrorr”：“notempty.admin.email”}]}

我建议您尝试清理maven存储库，从头开始构建项目。

我还应该提到，在testvalidation()集成测试中，您正在使用的admin0对象实际上是有效的，因此它通过验证是有意义的：）
