SpringBoot全局异常的捕获设置

1、新建立一个捕获异常的实体类

如：LeeExceptionHandler

package com.leecx.exception;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.servlet.ModelAndView;

@ControllerAdvice
public class LeeExceptionHandler {
    
    public static final String DEFAULT_ERROR_VIEW = "error";
    

    
    @ExceptionHandler(value = Exception.class)
    public Object errorHandler(HttpServletRequest reqest, HttpServletResponse response, Exception e) throws Exception {
        
        e.printStackTrace();
        
        if (isAjax(reqest)) {
            return response;
        } else {
            ModelAndView mav = new ModelAndView();
            mav.addObject("exception", e);
            mav.addObject("url", reqest.getRequestURL());
            mav.setViewName(DEFAULT_ERROR_VIEW);
            return mav;
        }
    }
    
    
    public static boolean isAjax(HttpServletRequest httpRequest){
        return  (httpRequest.getHeader("X-Requested-With") != null  && "XMLHttpRequest".equals( httpRequest.getHeader("X-Requested-With").toString()) ) ;
    }

    
}

在类上面加入注解：@ControllerAdvice

在处理方法上面加入注解@ExceptionHandler(value = Exception.class)

然后设置相应的业务处理。跳转到 特需的处理错误的友好业务界面。
