spring boot 全局异常处理

Posted 2021-03-01 Alex_zhuang

0.使用 @ ExceptionHandler 注解（Controller层面上）

   严格来说不是全局，是单类异常处理，进行异常处理的方法必须与出错的方法在同一个Controller里面。

package com.lvjing.controller;

import com.alibaba.fastjson.JSON;
import com.lvjing.bean.ResponseBeanWithCount;
import com.lvjing.common.ResponseBean;
import com.lvjing.dao.CommuteLogMapper;
import com.lvjing.domain.CommuteLog;
import lombok.extern.java.Log;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import javax.annotation.Resource;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
import java.util.Map;

public class CommuteLogController {

    private CommuteLogMapper commuteLogMapper;
    @Autowired
    private void setCommuteLogMapper(CommuteLogMapper commuteLogMapper){
        this.commuteLogMapper = commuteLogMapper;
    }

     */
    @RequestMapping(value = "/getCommuteLogList", method = RequestMethod.POST)
    public ResponseBeanWithCount getDeviceWarningLogList(@RequestBody Map<String, Object> paraMap) throws Exception {
        log.info("查询进出电子围栏人员列表,参数="+ JSON.toJSONString(paraMap));
        if ("0".equalsIgnoreCase(paraMap.get("id").toString())){
            throw new Exception("ID==0");
        }

        CommuteLog commuteLog = JSON.parseObject(JSON.toJSONString(paraMap), CommuteLog.class);
        if (paraMap.isEmpty()) {
            return new ResponseBeanWithCount(-1, "查询条件不能为空", 0, null);
        }
        int count = commuteLogMapper.queryCount(commuteLog);
        List<CommuteLog> deviceWarningLogs = commuteLogMapper.query(commuteLog);
        log.info("查询进出电子围栏人员列表,返回值="+ JSON.toJSONString(deviceWarningLogs));
        return new ResponseBeanWithCount(0, "查询成功!", count, deviceWarningLogs);
    }
    @ExceptionHandler({Exception.class})
    private ResponseBeanWithCount handleException(Exception e){
        e.printStackTrace();
        log.info(e.getMessage());
        return new ResponseBeanWithCount(-1, "查询失败", 0, null);
    }

}
