springMVC中得到request对象，session对象

标签：

    RequestAttributes ra = RequestContextHolder.getRequestAttributes();  
    HttpServletRequest request = ((ServletRequestAttributes)ra).getRequest();  
    request.getSession().setAttribute("sessionMessage", "im‘sessionMessage!");  

也可以让所有的Control继承一个BaseControl类 ，BaseControl类的定义为：

public class BaseControl{

protected HttpServletRequest request ; 

protected HttpServletResponse response ;

        protected HttpSession session ;

      // setter ... getter...

       //.......

}

@Component("SpringMVCInterceptor")
public class SpringMVCInterceptor extends HandlerInterceptorAdapter {


@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception {

                  BaseControl bc = (BaseController)handler ;
   bc.setRequest(request);

                    bc .setResponse(response);

   bc.set Session(request.getSession());
return super.preHandle(request, response, handler);
}
