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.boot
 spring-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
2017-06-16 14:54:05.314  WARN 6892 --- [nio-8080-exec-1] .m.m.a.ExceptionHandlerExceptionResolver : Resolved exception caused by Handler execution: org.springframework.dao.IncorrectResultSizeDataAccessException: result returns more than one elements; nested exception is javax.persistence.NonUniqueResultException: result returns more than one elements

2、页面处理异常

a、编写html模板页面 

 
异常出现啦
 ${messages}

b、修改Handler

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

@ControllerAdvice
public class GlobalExceptionHandler {

 @ExceptionHandler(value=Exception.class)
 @ResponseBody
 public String defaultErrorHandler(){
  System.out.println("-------------default error");
  return "系统错误，请联系管理员";
 }
}

c、页面访问结果
