怎么写切面

@Aspect
@Component
@Order(1000)
public class RequestContextAspect {

    @Around("execution(* com.ymm.trade.*.web.rest..*(..))")
    public Object around(ProceedingJoinPoint joinPoint) throws Throwable {
        try{
            HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
            RequestContext requestContext = build(request);
            RequestContextUtils.setRequestContext(requestContext);
            Object result = joinPoint.proceed();
            RequestContextUtils.resetRequestContext();
            return result;
        }catch (Throwable throwable){
            RequestContextUtils.resetRequestContext();
            throw throwable;
        }
    }

    public RequestContext build(HttpServletRequest request){
        String clientInfoStr = request.getHeader("Client-Info");
        String userAgentStr = request.getHeader("user-agent");
        AuthorizationUserDTO user = AuthorizationUserContext.currentAuthorizationUserDTO();
        if(Objects.isNull(user)){
            return new RequestContext(clientInfoStr, userAgentStr, 0L, 0);
        }else{
            // todo receive loginFrom from clientInfoStr
            return new RequestContext(clientInfoStr, userAgentStr, user.getUserId(), 0);
        }
    }
}

其中  RequestContextUtils

public class RequestContextUtils {

    public RequestContextUtils(){

    }

    private static ThreadLocal<RequestContext> requestContextThreadLocal = new ThreadLocal();

    public static void resetRequestContext(){
        requestContextThreadLocal.remove();
    }

    public static void setRequestContext(RequestContext requestContext){
        requestContextThreadLocal.set(requestContext);
    }

    public static RequestContext getRequestContext(){
        return requestContextThreadLocal.get();
    }
}
