struts2访问session,request,application

1.访问或添加request/session/application属性

public String scope() throws Exception{

ActionContextctx=ActionContext.getContext();

ctx.getApplication().put("app","应用范围");//往ServletContext里放入app

ctx.getSession().put("ses","session范围");//往session里放入ses

ctx.put("req","request范围");//往request里放入req

return"scope";

}

JSP:

<body>

${applicationScope.app}<br>

${sessionScope.ses}<br>

${requestScope.req}<br>

</body>
