I am using Spring Boot 2.0.0.M7. Github repo here@Configurationclass RoutesConfiguration { @Autowired private lateinit var testService: TestService @Autowired private lateinit var globalErrorHandler: GlobalErrorHandler @Bean fun routerFunction(): RouterFunction<ServerResponse> = router { ("/test").nest { GET("/") { ServerResponse.ok().body(testService.test()) } } }}@Componentclass GlobalErrorHandler() : WebExceptionHandler { companion object { private val log = LoggerFactory.getLogger(GlobalErrorHandler::class.java) } override fun handle(exchange: ServerWebExchange?, ex: Throwable?): Mono<Void> { log.info("inside handle") /* Handle different exceptions here */ when(ex!!) { is ClientException -> exchange!!.response.statusCode = HttpStatus.BAD_REQUEST is Exception -> exchange!!.response.statusCode = HttpStatus.INTERNAL_SERVER_ERROR } return Mono.empty() }} 更新：当我将Spring Boot版本更改为 2.0.0.M2 ，正在调用 WebExceptionHandler 。我需要为 2.0.0.M7 做些什么？When I change Spring Boot version to 2.0.0.M2, the WebExceptionHandler is getting called. Do I need to do something for 2.0.0.M7? 解决方案：按照Brian的建议，它的作用是As per Brian's suggestion, it worked as@Bean@Order(-2)fun globalErrorHandler() = GlobalErrorHandler()推荐答案您可以提供自己的 WebExceptionHandler ，但是您必须相对于其他用户订购它，否则他们可能会在您得到错误之前处理错误。机会尝试。You can provide your own WebExceptionHandler, but you have to order it relatively to others, otherwise they might handle the error before yours get a chance to try. Spring Boot提供的 DefaultErrorWebExceptionHandler （请参阅参考文档）在 -1 ResponseStatusExceptionHandler 在 0the DefaultErrorWebExceptionHandler provided by Spring Boot for error handling (see reference documentation) is ordered at -1the ResponseStatusExceptionHandler provided by Spring Framework is ordered at 0因此，您可以在错误处理组件上添加 @Order（-2），以便在现有组件之前进行订购。So you can add @Order(-2) on your error handling component, to order it before the existing ones. 这篇关于Spring 5 Reactive-未调用WebExceptionHandler的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
