本文为大家分享了Spring Boot全局异常处理，供大家参考，具体内容如下

1、后台处理异常

a、引入thymeleaf依赖

org.springframework.bootspring-boot-starter-thymeleaf

b、在application.properties文件中设置属性

#关闭thymeleaf模板的缓存 spring.thymeleaf.cache=false

c、编写后台处理Handler

import org.springframework.web.bind.annotation.ControllerAdvice; import org.springframework.web.bind.annotation.ExceptionHandler; @ControllerAdvice public class GlobalExceptionHandler { //设置此handler处理所有异常 @ExceptionHandler(value=Exception.class) public void defaultErrorHandler(){ System.out.println("-------------default error"); } }

d、后台异常打印

-------------default error
