比如上传文件超过了限制大小,就会抛出异常,此时可以通过@ControllerAdvice结合@ExceptionHandler定义全局异常捕获机制。 当我们没有定义异常捕获机制的时候,控制台会报错: 在src中添加exception文件夹,然后添加自定义异常处理类: CustomExceptionHandler.java package com.example.demo.exception; import java.io.IOException; im...
异常处理 在Spring Boot 中,可以通过@ExceptionHandler注解来处理异常。我们可以在 Controller 类中定义一个全局的异常处理方法,用来处理各种异常情况。 @ControllerAdvicepublicclassGlobalExceptionHandler{@ExceptionHandler(CustomException.class)@ResponseBodypublicResponseEntity<String>handleCustomException(CustomExceptionex){r...

webflux支持mvc的注解,是一个非常便利的功能,相比较于RouteFunction,自动扫描注册比较省事。异常处理可以沿用ExceptionHandler。如下的全局异常处理对于RestController依然生效。 @RestControllerAdvicepublicclassCustomExceptionHandler{privatefinalLog logger = LogFactory.getLog(getClass());@ExceptionHandler(Exception.class)@...
