[Series] AOP cut class to get a request logs

Back-end development process interface call log

Toss toss, changed and changed, how to get all fix?

Try this

Consuming interfaces into the database?

 	@Autowired
    SysLogMapper sysLogMapper;
    @Around("log()")
    public Object doAround(ProceedingJoinPoint point) {
        long beginTime = System.currentTimeMillis();
        try {
            return point.proceed();//放行操作
        } catch (Throwable throwable) {
            log.error(throwable.getMessage());
            return Result.getErrorResult("后台ERROR:" + throwable.getMessage());
            //return返回错误信息即可，本文没有提供Result类，自己处理即可。
        }finally {

            long time = System.currentTimeMillis() - beginTime;
            log.info("请求耗时={}", time);

            if (time>1000){//接口耗时超过1秒钟  加入日志到数据库
                HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
                String operation = "【耗时接口】";
                SysLog sysLog = new SysLog();
                sysLog.setOperation(operation);
                sysLog.setUrl(request.getRequestURL().toString());
                sysLog .setIp(request.getRemoteAddr());
                sysLog.setMethod(request.getMethod());
                sysLog.setParams(Arrays.toString(point.getArgs()));
                sysLog.setUseTime(time);
                sysLog.setCreateTime(new Date());
                sysLogMapper.insert(sysLog);
                log.info("耗时接口已加入日志");
            }

            //【知识点】finally 会在 try 和catch 的return语句之前执行，
            //如果finally内又return,try和catch里的return不生效

        }
