AOP日志

通过AOP切面来实现日志，打印出用户请求的URL，携带的参数，用户的ID及姓名，响应结果，耗时等信息，这样我们就可以根据用户来进行排查错误

@Aspect
@Component
@Slf4j
@EnableAspectJAutoProxy
public class RequestAspect {

    //切点为controller层
    @Pointcut("execution(public * com.djn.web.controller.*.*(..)))")
    public void requestCutPoint() {

    }

    @Around("requestCutPoint()")
    public Object doAround(ProceedingJoinPoint call) throws Throwable {

        ServletRequestAttributes servletRequestAttributes =
                (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = servletRequestAttributes.getRequest();
        //请求url
        // 记录下请求内容
        //用户的信息，我这里用的Shiro
        User user = (User) SecurityUtils.getSubject().getSession().getAttribute(Const.CURRENT_USER);
        if (user == null) {
            user = new User(0, "未登录", "", 0);
        }
        log.info("################ api日志开始 ################");
        log.info("请求用户 id={}, phone={} : ", user.getUserId(), user.getUsername());
        log.info("请求URL : " + request.getRequestURL().toString());
        log.info("请求HTTP_METHOD : " + request.getMethod());
        //请求参数
        Object[] args = call.getArgs();
        if (args != null) {
            StringBuilder sb = new StringBuilder("userId=" + user.getUserId() + "|");
            for (Object arg : args) {
                if (arg instanceof HttpServletRequest) {
                    continue;
                } else if (arg instanceof HttpServletResponse) {
                    continue;
                }
                sb.append(arg);
                sb.append("|");
            }
            log.info("请求参数: " + sb);
        }

        Long startTimeStamp = System.currentTimeMillis();
        try {
            // 请求处理
            Object object = call.proceed();
            log.info("【响应结果】: " + (null != object ? JSONObject.toJSONString(object) : null));
            return object;
        } catch (Exception e) {
            log.error("服务请求处理异常", e);
            return ServerResponse.createByError("服务请求处理异常");
        } finally {
            log.info("################ api日志结束 耗时: {}毫秒 ################", (System.currentTimeMillis() - startTimeStamp));
        }
    }
}
