这篇文章主要为大家详细介绍了Spring Boot全局异常处理的相关资料，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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
<!-- thymeleaf模板插件 --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>
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
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org"
xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3">
<head>
<meta charset="UTF-8" />
<title>Insert title here</title>
</head>
<body>
<h1 th:inlines="text">异常出现啦</h1>
${messages}
</body>
</html>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
