SpringBoot 不处理 org.hibernate.exception.ConstraintViolationException

java spring-boot jpa-2.0

我已经定义了一个用于在我的实体类中验证电子邮件的模式。在我的验证异常处理程序类中，我为 ConstraintViolationException 添加了处理程序。我的应用程序使用SpringBoot 1.4.5。

简介.java

@Entity
@EntityListeners(AuditingEntityListener.class)
@Table(name = "profile")
public class Profile extends AuditableEntity {

  private static final long serialVersionUID = 8744243251433626827L;

  @Column(name = "email", nullable = true, length = 250)
  @NotNull
  @Pattern(regexp = "^([^ @])+@([^ \\.@]+\\.)+([^ \\.@])+$")
  @Size(max = 250)
  private String email;
....
}

ValidationExceptionHandler.java

@ControllerAdvice
public class ValidationExceptionHandler extends ResponseEntityExceptionHandler {

  private MessageSource messageSource;

  @Autowired
  public ValidationExceptionHandler(MessageSource messageSource) {
    this.messageSource = messageSource;
  }

  @ExceptionHandler(ConstraintViolationException.class)
  public ResponseEntity<Object> handleConstraintViolation(ConstraintViolationException ex,
  WebRequest request) {
    List<String> errors = new ArrayList<String>();
    ....
    }
}

当我运行代码并传递无效的电子邮件地址时，我收到以下异常。句柄冲突中的代码永远不会执行。异常中返回的 http 状态为 500，但我想返回 400。任何想法，我怎么能做到这一点？

答案 1

您无法捕获，因为它没有传播到代码的该层，它被较低的层捕获，在另一种类型下包装和重写。因此，命中 web 图层的异常不是 .ConstraintViolationException.classConstraintViolationException

在我的情况下，它是一个.我正在使用来自Spring的注释和.当事务中出现问题时，EntityManager 会引发回滚异常，该异常由 .TransactionSystemException@TransactionalJpaTransactionManagerTransactionSystemExceptionJpaTransactionManager

所以你可以做这样的事情：

@ExceptionHandler({ TransactionSystemException.class })
public ResponseEntity<RestResponseErrorMessage> handleConstraintViolation(Exception ex, WebRequest request) {
    Throwable cause = ((TransactionSystemException) ex).getRootCause();
    if (cause instanceof ConstraintViolationException) {
        Set<ConstraintViolation<?>> constraintViolations = ((ConstraintViolationException) cause).getConstraintViolations();
        // do something here
    }
}

答案 2

只是想添加一些东西。我试图做同样的事情，验证实体。然后我意识到，如果你验证控制器的输入，Spring已经具备了开箱即用的一切。

@RequestMapping(value = "/profile", method = RequestMethod.POST)
public ProfileDto createProfile(@Valid ProfileDto profile){
...    
}

该注释将使用 javax.validation 注释触发验证。@Valid

假设您在配置文件用户名上有一个 Pattern 注释，其中正则表达式不允许空格。

Spring 将构建一个状态为 400（错误请求）的响应，并构建一个如下所示的正文：

{
    "timestamp": 1544453370570,
    "status": 400,
    "error": "Bad Request",
    "errors": [

                "Pattern.username",
                "Pattern.java.lang.String",
                "Pattern"
            ],
            "arguments": [
                {
                    "codes": [
                        "profileDto.username",
                        "username"
                    ],
                    "arguments": null,
                    "defaultMessage": "username",
                    "code": "username"
                },
                [],
                {
                    "defaultMessage": "^[A-Za-z0-9_\\-.]+$",
                    "arguments": null,
                    "codes": [
                        "^[A-Za-z0-9_\\-.]+$"
                    ]
                }
            ],

        }
    ],
