Spring AOP 获取request，各种数值

[jsp]代码库

package com.wang.aop;

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

import org.aspectj.lang.JoinPoint;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import com.wang.model.User;

public class Log {
	
	public void before(JoinPoint jp){
		// 获取session中当前用户
		HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
		HttpSession session = request.getSession();
		User user = (User)session.getAttribute("user");
		System.out.println(user.getAccount());
		System.out.println(user.getUsername());
		
		String ip = request.getRemoteAddr(); // 获取IP地址
		System.out.println(ip);
		
		Object[] objs = jp.getArgs(); // 获取方法的输入参数
		for(int i=0;i<objs.length;i++){
			System.out.println("参数" + i + ":" + objs[i]);
		}
		
		String className = jp.getTarget().getClass().getSimpleName(); // 获取包含当前方法的对象的名字
		String methodName = jp.getSignature().getName(); // 获取方法名
		System.out.println(className + "." + methodName + "()");
	}
	
}


获取request还要在web.xml下配置
<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>  
  </listener>
监听
