spring aop用切面注解@Befor报错org.springframework.beans.factory.BeanCreationException

在Spring aop切面用注解@Before，方法名中加参数报错：

@Aspect
@Component
public class CheckAuthority {

	@Before("execution(* com.njl.web.controller..*.*(..))")
	public Object beforeSayHello(ProceedingJoinPoint jp,HttpServletRequest request,HttpServletResponse response){  
		try {
			System.out.println("------------------验证权限----------------");
			return jp.proceed();
		} catch (Throwable e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			return null;
		}
	} 
}

解决方案：
@Before是在所拦截方法执行之前执行一段逻辑。
@After 是在所拦截方法执行之后执行一段逻辑。
@Around是可以同时在所拦截方法的前后执行一段逻辑。

方法名中传参数，不能用ProceedingJoinPoint jp,HttpServletRequest request,HttpServletResponse response

[code]
package com.njl.web.security;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.springframework.stereotype.Component;


@Aspect
@Component
public class CheckAuthority {

@Before("execution(* com.njl.web.controller..*.*(..))")
public void beforeSayHello(JoinPoint jp){
Object[] args = jp.getArgs();
if(args.length>=3)
{
HttpServletRequest request=(HttpServletRequest)args[0];
HttpSession session=request.getSession();
System.out.println("---"+session.getAttribute("Njl_User")+"---");
}

System.out.println("------------------验证权限----------------");
}
}[/code]
