浏览器的“多个"标签-JSF 1.2广告 [英] Browser Multiples Tabs - JSF 1.2 ad

问题描述

我正在使用JSF 1.2 + RichFaces系统.该系统是一种博客.用户可以创建他们的博客并进行管理.可通过以下网址类型访问博客:

I'm working on a JSF 1.2 + RichFaces system. This system is a kind of blog. Users can create their blogs and manage them. Blogs are accessible by a url type this:

www.meublog.com/NameOfBlog

我使用一个具有会话范围的单个Managed Bean来进行所有控件.当用户访问博客时，我使用了一个过滤器，该过滤器通过URL(用于标识正在访问的博客)将URL的ID放入会话中，并为博客索引提供了转发. 我使用此会话ManagedBean来控制博客视图中的所有内容. 问题在于浏览器在多个选项卡之间共享相同的会话.当用户在一个选项卡上使用www.meublog.com/julio在另一个选项卡上使用www.meublog.com/fulano来访问博客时，由于仅建立了一个会话，因此我无法识别两个博客.

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正确的方法……

I wonder to know if anyone knows the correct path to follow here ...

推荐答案

基于所面临的确切原因，您不应在会话范围内存储请求范围的信息.请使用请求范围内的受管bean代替，它根据请求URI进行初始化.您可以通过 ExternalContext获取大多数请求的详细信息. 和/或 HttpServletRequest .

You should not store request scoped information in the session scope for exactly the reasons you're facing. Use a request scoped managed bean instead which get initialized based on the request URI. You can get most of the request details by ExternalContext and/or HttpServletRequest.

例如，在bean的构造函数或@PostConstruct方法内部:

E.g., inside bean's constructor or @PostConstruct method:

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.
