使用 webflux bean 验证时出现不明确的异常（WebExchangeBindException 与 ConstraintViolationException）

Question

我正在使用 webflux，我将继续使用 bean 验证进行现场验证。

尝试使用@RestControllerAdvice 响应字段错误

在bean验证字段中指定组时我可以知道异常类型不同的原因吗？

未指定组时发生 WebExchangeBindException 异常。当您指定组时，会发生 ConstraintViolationException 异常。

我想要一个统一的异常，我想知道@RestControllerAdvice是否应该单独管理异常。

我查了一下。我不认为 AbstractMessageReaderArgumentResolver 使用组来验证字段...

我想要一个统一的例外。 WebExchangeBindException 或 ConstraintViolationException

Answer 1

使用

@Size(min = 1, max = 10)

或

@Pattern(regexp = "^\w{1,10}$")

而不是

@Length(min = 1, max = 10)

Answer 2

解决了这个问题。

验证组字段时使用@Validated

我找到了这个 post。

https://www.baeldung.com/spring-valid-vs-validated

In Spring, we use JSR-303's @Valid annotation for method level validation. Moreover, we also use it to mark a member attribute for validation. However, this annotation doesn't support group validation. Groups help to limit the constraints applied during validation. One particular use case is UI wizards. Here, in the first step, we may have a certain sub-group of fields. In the subsequent step, there may be another group belonging to the same bean. Hence we need to apply constraints on these limited fields in each step, but @Valid doesn't support this.

使用 webflux bean 验证时出现不明确的异常（WebExchangeBindException 与 ConstraintViolationException）
