springboot 全局异常拦截器,友好异常提示

1. 添加config 配置类

package org.fh.config;


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

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.view.json.MappingJackson2JsonView;

/**
 * 说明:错误异常拦截处理

 * from fhadmin.cn
 */
@Configuration
public class ExceptionConfiguration implements HandlerExceptionResolver {

    @Override
    public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler,
            Exception ex) {
        ModelAndView mv = new ModelAndView(new MappingJackson2JsonView());    //返回json
        
        String exInfo = ex.toString().replaceAll("
", "<br/>");
        
        boolean status = exInfo.contains("Subject does not have permission");
        
        if(status){
            exInfo = "[没有此页面的访问权限]" + exInfo;
        }else {
            System.out.println("==============异常开始=============");
            ex.printStackTrace();
            System.out.println("==============异常结束=============");
        }
        mv.addObject("exception", exInfo);
        mv.addObject("result", "exception");
        
        return mv;
    }
    
}
