spring boot统一异常页面

只需要创建一个类就可以了

package com.ulic.gis.securityManage.controller;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.web.servlet.error.ErrorAttributes;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.context.request.ServletWebRequest;
import org.springframework.web.servlet.ModelAndView;

@ControllerAdvice
public class GlobalExceptionHandler {
    private static final Logger log = LoggerFactory.getLogger(GlobalExceptionHandler.class);
    @Autowired
    private ErrorAttributes errorAttributes;
    /**
     * 出现异常之后会跳转到此方法
     * @param request
     * @param e
     * @return
     */
    @ExceptionHandler(Exception.class) 
    public ModelAndView defaultErrorHandler(HttpServletRequest request, Exception e) {
        ModelAndView mav = new ModelAndView("/exception/blank"); 
        Map<String, Object> map = getErrorAttributes(request, false);
        log.info("错误码status:{}",map.get("status"));
        //log.info("失败的请求:{}",map.get("URL"));
        mav.addObject("message","请求失败,存在异常数据");
        return mav;
    }
     
    private Map<String, Object> getErrorAttributes(HttpServletRequest request,
            boolean includeStackTrace) {

        ServletWebRequest servletWebRequest = new ServletWebRequest(request);
        Map<String, Object> map = this.errorAttributes.getErrorAttributes(servletWebRequest,includeStackTrace);
        String URL = request.getRequestURL().toString();
        map.put("URL", URL); 
        return  map;
    }
}
