Hibernate 使用@NotBlank注释提交事务时测试失败，出现错误

hibernate spring-boot validation exception

Hibernate 使用@NotBlank注释提交事务时测试失败，出现错误,hibernate,spring-boot,validation,exception,Hibernate,Spring Boot,Validation,Exception,以下是包含@NotBlank注释的实体： import javax.validation.constraints.NotBlank; //... @Entity(name = "funds") @SQLDelete(sql = "UPDATE funds SET deleted_at = now() WHERE id = ?") @Where(clause = "deleted_at is null") public class Fund implements Serializable {

以下是包含@NotBlank注释的实体：

import javax.validation.constraints.NotBlank;
//...

@Entity(name = "funds")
@SQLDelete(sql = "UPDATE funds SET deleted_at = now() WHERE id = ?")
@Where(clause = "deleted_at is null")
public class Fund implements Serializable {

  @Column(nullable = false)
  @NotBlank(message = "Name is mandatory")
  private String name;

  ...

这是我的休息控制器：

@RestController
@RequestMapping("/funds")
public class FundController
{
    @Autowired
    private FundRepository fundRepository;

    @RequestMapping(value = "/create", method = RequestMethod.POST)
    @ResponseStatus(HttpStatus.CREATED)
    public @ResponseBody Fund create(
        @RequestParam("name") String name,
        @RequestParam(value = "amount", required = false, defaultValue = "0") Double amount,
        @RequestParam("currency") Integer currencyId,
        Principal principal) {

        Fund fund = new Fund(name, amount);
        //...
        return fundRepository.save(fund);
    }

    //...

    @ResponseStatus(HttpStatus.BAD_REQUEST)
    @ExceptionHandler(ConstraintViolationException.class)
    public String handleValidationExceptions(ConstraintViolationException e) {
        return e.getMessage();
    }

下面是对字段验证器的测试：

@RunWith(SpringRunner.class)
@WebAppConfiguration
@SpringBootTest(classes = Application.class)
public class FundsControllerTest extends ControllerTest {

    @Test
    public void testCreateFund_whenFieldsInValid_thenBadRequest() throws Exception {

        String accessToken = getAccessToken(USER_USERNAME, USER_PASSWORD);

        mockMvc.perform(
            post("/funds/create")
                .header("Authorization", "Bearer " + accessToken)
                .param("name", "") // empty 
                .param("amount", "1000")
                .param("currency", currency.getId().toString())
            ).andExpect(status().isBadRequest());
    }

但是，我看到了以下错误：

不能包含空字符串。但是您输入了一个空字符串，因此会得到一个异常。我不知道你为什么会期望其他任何东西。我不希望得到一个未处理的异常。我希望得到4xx的回复。当一个字段无效时，为什么它会试图插入数据库？好的，这是关于异常转换和处理的更多信息。这些可能会有帮助：为什么它在不应该验证的情况下尝试更新数据库？@NotBlank被忽略了，这就是我想要理解的。
