全局异常处理

一、定义全局异常配置

package com.xiaoxu.ssmp.utils;

import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;

@RestControllerAdvice //springmvc 的异常处理器
public class GolbalException {

    @ExceptionHandler  //异常处理器 可指定具体异常类型
    public  Result golbalException(Exception e){
        //记录日志
        //通知运维
        //通知开发

        e.printStackTrace();//将异常打印在控制台
        return new Result(false,null,"服务器异常，请稍后再试");
    }
}

二、修改结果工具类

package com.xiaoxu.ssmp.utils;

import lombok.Data;

@lombok.Data
public class Result {
    private  Boolean flag;
    private  Object  data;
    private  String msg;
    public Result(){

    }

    public Result(Boolean flag){
        this.flag = flag;
    }

    public Result(Boolean flag,Object object){
        this.flag = flag;
        this.data = object;
    }



    public Result(Boolean flag,Object data,String msg){
        this.flag = flag;
        this.data = data;
        this.msg = msg;
    }
}
