gwt + spring通过aop记录日志获取request、session

由于Spring 的AOP面向切面编程，与Servlet容器没有任何关联，所以想要获得Session会话比较麻烦。
当然Struts2同样不依赖Servlet容器，可以在Spring AOP中可以使用com.opensymphony.xwork2.ActionContext，就可以获得Session。
但是在Servlet中或struts1中，可以通过ThreadLocal方式将session保存，Spring AOP中获得Session对象。
具体思路和代码：

这个是保存request和session的类
/**
*
* @author 株洲健坤北大青鸟 周钢
*
*/
public class SysContent { 
     private static ThreadLocal<HttpServletRequest> requestLocal= new ThreadLocal<HttpServletRequest>(); 
     private static ThreadLocal<HttpServletResponse> responseLocal= new ThreadLocal<HttpServletResponse>(); 
      
    public static HttpServletRequest getRequest() { 
        return (HttpServletRequest)requestLocal.get(); 
    } 
    public static void setRequest(HttpServletRequest request) { 
        requestLocal.set(request); 
    } 
    public static HttpServletResponse getResponse() { 
        return (HttpServletResponse)responseLocal.get(); 
    } 
    public static void setResponse(HttpServletResponse response) { 
        responseLocal.set(response); 
    } 
    public static HttpSession getSession() { 
        return (HttpSession)((HttpServletRequest)requestLocal.get()).getSession(); 
    } 
}


这个是配置的过滤器

/**
*
* @author 株洲健坤北大青鸟 周钢
*
*/
public class GetContent implements Filter { 
    @Override 
    public void destroy() { 
        // TODO Auto-generated method stub 
    } 
    @Override 
    public void doFilter(ServletRequest arg0, ServletResponse arg1, 
            FilterChain arg2) throws IOException, ServletException { 
        SysContent.setRequest((HttpServletRequest) arg0); 
        SysContent.setResponse((HttpServletResponse) arg1); 
        arg2.doFilter(arg0, arg1); 
    } 
    @Override 
    public void init(FilterConfig arg0) throws ServletException { 
        // TODO Auto-generated method stub 
    } 
} 



使用AOP进行环绕通知切入所有com.aptech.service包下的所有类的方法

/**
* @author 株洲健坤北大青鸟 周钢
*/
@Aspect
public Class AopTest{
@Around(value="execution(* com.aptech.service.*.*(..))")
public void aroundTest(ProceedingJoinPoint pj) throws Exception { 
          HttpServletRequest request = SysContent.getRequest(); 
          HttpServletResponse response = SysContent.getResponse(); 
          HttpSession session = SysContent.getSession(); 
          //其他操作
          if(true){
           pj.proceed();
          }
          throw new Exception("您没有该权限");
    }
}
