使用Spring AOP捕获Http状态代码的正确方法是什么？

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;

@Aspect
@Component
public class HttpStatusAspect {

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

    @Before("controllerPointcut()")
    public void beforeControllerMethod(JoinPoint joinPoint) {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        int httpStatus = request.getStatus();
        // 处理Http状态代码
    }

    @AfterReturning(pointcut = "controllerPointcut()", returning = "result")
    public void afterControllerMethod(JoinPoint joinPoint, Object result) {
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        int httpStatus = request.getStatus();
        // 处理Http状态代码
    }
}
