Question

我正在尝试使默认的Spring 400约束违反错误起作用。我期望这样：

{
    ....
    "status": 400,
    "error": "Bad Request",
    "errors": [
        {
            ....
            "defaultMessage": "must not be null",
            ....
        }
    ],
    "message": "Validation failed for object='notNullRequest'. Error count: 1",
    ....
}

但是我得到了

{
    "timestamp": "2020-07-31T08:30:06.992+00:00",
    "status": 400,
    "error": "Bad Request",
    "message": "",
    "path": "/v0.1/checkouts/1"
}

我正在尝试验证的REST资源：

@PutMapping(value = "/{id}", produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<CheckoutDto> createCheckout(@PathVariable Long id,
                                                  @Valid @RequestBody CheckoutProcessRequest request) {

DTO的验证如下：

@NotNull
@JsonProperty("payment_type")
private PaymentType paymentType;

我在日志中收到一条正确的消息：

2020-07-31 11:30:06.983  WARN 93126 --- [nio-8080-exec-1] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.bind.MethodArgumentNotValidException: Validation failed for argument [1] in public org.springframework.http.ResponseEntity<com.hidden.payments.rest.model.CheckoutDto> com.hidden.payments.rest.CheckoutsResource.createCheckout(java.lang.Long,com.hidden.payments.rest.model.CheckoutProcessRequest): [Field error in object 'checkoutProcessRequest' on field 'paymentType': rejected value [null]; codes [NotNull.checkoutProcessRequest.paymentType,NotNull.paymentType,NotNull.com.hidden.payments.rest.model.PaymentType,NotNull]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [checkoutProcessRequest.paymentType,paymentType]; arguments []; default message [paymentType]]; default message [must not be null]] ]

那么有什么想法会干扰响应？我没有回想过必须做任何特定的事情才能在最新的Spring版本中获得正确的约束违反响应。

谢谢！

Answer 1

Spring Boot 2.3默认情况下在错误响应中省略了errors和message字段，以减少敏感信息包含在响应中的机会。您可以通过设置以下属性来还原以前的行为：

server.error.include-message=always
server.error.include-binding-errors=always

有关更多信息，请参见2.3 release notes和documentation。

Answer 2

Sprint Boot 2.3的验证消息有问题，或行为已更改。下的重复问题 Size Annotation in Spring Boot is returning 400 Bad Request

Spring不返回默认验证错误响应
