@ControllerAdvice在Junit测试中不处理异常

Question

我正在使用Spring MVC 4.1并进行Junits测试。 在上一次测试中，我检查了错误/缺失的参数。 但是我有400个异常，但我希望该异常采用以下格式：code（400），msg，error（参数错误），action。 有人告诉我为此使用@ControllerAdvice，但测试未调用控制器。

checkAccountTest.java

    @SuppressWarnings("unused")
    @NotNull
    private Object[] checkAccount_BadParams_ParametersToTest() {
        return new Object[]{

                new Object[]{"All params are missing", "", "", HttpStatus.OK, NotBlank.class.getSimpleName()},
                new Object[]{"Account is missing", "", regionName, HttpStatus.OK, NotBlank.class.getSimpleName()},
                new Object[]{"Region name is missing", "valid@mail.com", "", HttpStatus.OK, NotBlank.class.getSimpleName()},

                new Object[]{"Not valid email format", "kukuriku", regionName, HttpStatus.OK, UserNameConstraint.class.getSimpleName()},
                new Object[]{"Too short email address", "@c", regionName, HttpStatus.OK, Size.class.getSimpleName()},
                new Object[]{"Too short user name", "97", regionName, HttpStatus.OK, Size.class.getSimpleName()},
                new Object[]{"Too long user name", new StringBuilder(255), regionName, HttpStatus.OK, Size.class.getSimpleName()}
        };
    }

    @Test
    @Parameters(method = "checkAccount_BadParams_ParametersToTest")
    @TestCaseName("{0}.  Account: {1}, Region: {2}")
    public void checkAccount_BadParams_ShouldReturn_HttpStatus400(
            String testName,
            String account,
            String regionName,
            HttpStatus expectedStatus,
            String customExpectedStatus) throws Exception {


        var dto = new CheckAccountRequestDto();
        dto.setAccount(account);
        dto.setRegionName(regionName);


        var result = (ExceptionResult) sendRequest(dto, expectedStatus, SysConstant.PARAM_ERROR);
        //        assertThat(result.getErrors()).anyMatch(detailedError -> detailedError.ErrorType.equals(customExpectedStatus));
        assertThat(result.getError()).isEqualTo(true);

    }

ConstraintViolationExceptionResult.java

@JsonRootName(value = "exceptionResult")
@Data
public class ConstraintViolationExceptionResult extends ExceptionResult {

    public List<DetailedError> getErrors() {
        return errors;
    }

    public void setErrors(List<DetailedError> errors) {
        this.errors = errors;
    }

    public static class DetailedError{
        public String ErrorType;
        public String ErrorMessage;
    }

    private List<DetailedError> errors = new ArrayList<DetailedError>();

    public ConstraintViolationExceptionResult() {
    }

    public ConstraintViolationExceptionResult(Integer code, Object msg, String error, String action)  {
        super(code, msg, error, action);
    }
}

GlobalControllerExceptionHandler.java

@ControllerAdvice
public class GlobalControllerExceptionHandler {

    private Logger logger = LoggerFactory.getLogger(GlobalControllerExceptionHandler.class);

    @ResponseStatus(value=HttpStatus.OK)
    @ExceptionHandler(ConstraintViolationException.class)
    public ResponseEntity<ConstraintViolationExceptionResult> handleConflict(ConstraintViolationException e) {

        logger.error(e.getMessage(), e);

        var d = new Result();

        var errorInfo = new ConstraintViolationExceptionResult();
        errorInfo.setMsg(e.getMessage());
        errorInfo.setCode(SysConstant.PARAM_ERROR);
        errorInfo.setError(e.getMessage());

        var errors = errorInfo.getErrors();

        for (var error : e.getConstraintViolations()) {

            var err = new ConstraintViolationExceptionResult.DetailedError();
            err.ErrorType = error.getConstraintDescriptor().getAnnotation().annotationType().getSimpleName();
            err.ErrorMessage = error.getMessage();
            errors.add(err);

        }
        return new ResponseEntity<ConstraintViolationExceptionResult>(errorInfo, new HttpHeaders(), HttpStatus.OK);
    }
}

发送请求功能：

    protected ExceptionResult sendRequest(Object dto,
                                     HttpStatus expectedStatus, int customExpectedStatus)
            throws JsonProcessingException {


        String body = null;
        if(dto != null){

            var objectMapper = new ObjectMapper();
            body = objectMapper.writeValueAsString(dto);
        }

        var entity = new HttpEntity<>(body, getBaseHttpHeaders());

        var response = _restTemplate.postForEntity(get_Url(),
                entity,
                ExceptionResult.class);

        assertThat(response.getStatusCode()).isEqualTo(expectedStatus);

        var responseDto = response.getBody();

        assertThat(responseDto.getCode()).isEqualTo(customExpectedStatus);

        return responseDto;
    }
