package com.dl.ExceptionTest;

import com.alibaba.fastjson.JSONObject;
import org.springframework.web.bind.annotation.RestControllerAdvice;

@RestControllerAdvice
public class ExceptionHandler {
    @org.springframework.web.bind.annotation.ExceptionHandler(value = Exception.class)
    public Object defaultHandler(HttpServletRequest req,Exception e){
        JSONObject object = new JSONObject();
        object.put("code","500");

返回页面

package com.dl.ExceptionTest;

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

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

/**
 * @author xingguanghui
 * @create 2018-04-03 11:05
 **/
@ControllerAdvice
public class ExceptionHandler1 {

    @ExceptionHandler(value = Exception.class)
    public Object errHandler(HttpServletRequest req, HttpServletResponse rsp,Exception e) throws Exception{
        e.printStackTrace();
        ModelAndView model = new ModelAndView();
        model.addObject("exception",e);
        model.addObject("url",req.getRequestURL());
        model.setViewName("error");
        return model;
    }
}

判断请求是不是ajax请求

/**
 * 判断请求是否是ajax请求
 * @param req
 * @return
 */
public static boolean isAjax(HttpServletRequest req){
    String header = req.getHeader("X-Requested-With");
    return (header != null && "XMLHttpRequest".equals(header));
}

集成两种返回

package com.dl.ExceptionTest;

import com.alibaba.fastjson.JSONObject;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;

/**
 * @author xingguanghui
 * @create 2018-04-03 10:51
 **/
@RestControllerAdvice
public class ExceptionHandler {
    @org.springframework.web.bind.annotation.ExceptionHandler(value = Exception.class)
    public Object defaultHandler(HttpServletRequest req,Exception e){
        e.printStackTrace();
        if(isAjax(req)){
            JSONObject object = new JSONObject();
            object.put("code","500");
            object.put("msg",e.getMessage());
            return object;
        }else{
            ModelAndView model = new ModelAndView();
            model.addObject("exception",e);
            model.addObject("url",req.getRequestURL());
            model.setViewName("error");
            return model;
        }
    }

    /**
     * 判断请求是否是ajax请求
     * @param req
     * @return
     */
    public static boolean isAjax(HttpServletRequest req){
        String header = req.getHeader("X-Requested-With");
        return (header != null && "XMLHttpRequest".equals(header));
    }
