Spring-Aop实现用户操作日志记录 aop获取session

Spring-Aop获取session
第一种获取session方式

  ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.currentRequestAttributes();
  HttpSession session = attr.getRequest().getSession(true);
  User user = (User) session.getAttribute("user");

这种方式会引发一个错误，错误消息如下：

  java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request. 

解决方式如下:
在web.xml中添加一个监听

  <listener>
        <listener-class>
        org.springframework.web.context.request.RequestContextListener
        </listener-class>
   </listener>
</web-app>

第一种获取session方式

public Object around(ProceedingJoinPoint joinPoint)
  {
    HttpServletRequest request=null;
    for(int i=0;joinPoint.getArgs().length;i++){
        if((joinPoint.getArgs()[i] instanceof HttpServletRequest)){
            request=(HttpServletRequest )joinPoint.getArgs()[i];
        }
    }
    if(request!=null){
      if(request.getSession()!=null){
        User user=(User)request.getSession().getAttribute("user");
        if(user==null){
          return joinPoint.proceed();
        }
        业务操作
      }
    }
    return joinPoint.proceed();
  }
