SpringAOP 環繞通知避坑

環繞通知必須有返回值，返回值即爲目標方法的返回值，不然目標方法會沒法結束，致使前端請求認爲超時！
return object;
必須有，別問，問就是被坑過

@Aspect
@Component
public class WebLogAspect {

    private Logger logger = LoggerFactory.getLogger(getClass());

    @Pointcut("execution(public * com.example.liaowh.controller..*.*(..))")
    public void webLog() {
    }

    @Around("webLog()")
    public Object around(ProceedingJoinPoint joinPoint) throws Throwable {

        // 接收到請求，記錄請求內容
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();

        // 記錄下請求內容
        logger.info("URL : " + request.getRequestURL().toString());
        logger.info("HTTP_METHOD : " + request.getMethod());
        logger.info("IP : " + request.getRemoteAddr());
        logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
        logger.info("ARGS : " + Arrays.toString(joinPoint.getArgs()));
        Object object = joinPoint.proceed(joinPoint.getArgs());
        logger.info("return" + object);
        return object;
    }
}
