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
Insert title here 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
