Question

我正在研究一个 JSF 1.2 + Richfaces 系统。这个系统是一种博客。用户可以创建和管理他们的博客。博客可以通过以下型号的 URL 访问 :

www.meublog.com/NameOfBlog

I used a single Managed Bean with session scope to make all controls. When the user accesses the blog, I use a filter that through the URL, which identified the blog being accessed, put the ID of the blog in the session and gave foward to the blog index. I used this session ManagedBean to control everything in the view of the blog. The problem is that the browser shares the same session between multiple tabs. When a user accesses the blog like this www.meublog.com/julio on one tab and www.meublog.com/fulano in another tab, I can not identify the two blogs because I have only one session established.

我想知道是否有人知道走这条正确的道路...

您不应因为所要面对的原因而将范围信息存储在会议范围中。使用范围管理豆类的请求, 而不是根据请求 URI 初始化。您可以通过< a href="http://docs. oracle.com/javaee/5/ api/javax/faces/context/ ExternalContext.html" rel= “ nofollown noreferrr" code>ExternalCortext 和/ 或 < a href="http://docs. oracle.com/javaee/5/api/javax/servlet/http/ Htpservletes.html" rel=“ nofolpn noreferr"\code> Htpservertlett 。

例如,在豆类构造或

ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();

// If you use suffix mapping like *.jsf
String servletPath = ec.getRequestServletPath(); 

// Or if you use prefix mapping like /faces/*
String pathInfo = ec.getRequestPathInfo();

// Now initialize based on the value of either servletPath or pathInfo.
