如何在jsf中创建用户友好和seo友好的URL? [英] How to create user-friendly and seo-friendly urls in jsf?

问题描述

例如，我有一个带有方法getTitle ()和getContent ()的Article类.

For example, I have class Article with methods getTitle () and getContent ().

我还有使用方法getAllArticles ()的ArticlesService.如何创建具有有意义名称的链接列表(由#{article.title}组成)?喜欢:

I also have ArticlesService with method getAllArticles (). How to create a list of links with meaningful names (formed with #{article.title})? Like:

http://mysiteaddress.com/article/first-article-title
http://mysiteaddress.com/article/how-to-make-links-in-jsf

..或类似的东西.

我可以使用<h:commandLink>创建具有所有必要功能的链接，但是我不知道如何为此做一个很好的"href":它总是带有href'#'.

I can create links with all necessary functionality with <h:commandLink>, but I don't know how to make nice 'href' for it: it always has href '#'.

我可以使用<h:outputLink>创建漂亮的链接，但是我不知道如何向其中添加必要的功能.

I can create nice links with <h:outputLink> but I don't know how to add necessary functionality to it.

在jsp中，我创建了自己的前端控制器，该控制器解析请求中的url，然后执行重定向到相应的jsp-page.

In jsp I created my own front-controller, which parsed urls from requests and then performed redirection to correspondent jsp-page.

如何在JSF中实现相同的功能?

推荐答案

如果这是对现有应用程序的改进，则基本上需要如何在Java中使用servlet过滤器来更改传入的servlet请求url?

If this is intended as an improvement of an existing application, then you basically need a Filter which detects "dirty" and "friendly" URLs. When it detects a "dirty" URL, then it should redirect the request to a "friendly" URL by HttpServletResponse#sendRedirect(). When it detects a "friendly" URL, then it should forward the request to the "dirty" URL by RequestDispatcher#forward(). An example can be found in this related question: How to use a servlet filter in Java to change an incoming servlet request url?

此外，您还需要自定义 为JSF <h:form>，<h:link>等生成所需的友好" URL.可以在此处找到示例:

Further, you also need a custom ViewHandler to produce the desired "friendly" URL for JSF <h:form>, <h:link>, etc. An example can be found here: Dynamic Directory in Java EE Web Application.

如果这是一个新应用程序或可以更改的应用程序，则可以考虑使用任何现有的漂亮URL库，而无需重新发明轮子:

If this is a new application or an application which is open to changes, you could consider any of the existing pretty URL libraries instead of reinventing the wheel:

• PrettyFaces ，这是一个完整的URL重写解决方案.它需要一个附加的XML配置文件pretty-config.xml.如果您要完全更改URL和/或配置从旧URL到新URL的重定向，则此库很有用.
• FacesViews "nofollow noreferrer> OmniFaces 库，该库使现有的URL只能通过单个web.xml上下文参数进行扩展.它还支持"MultiViews"，从而可以声明性地将路径参数注入到托管bean中.例如. /foo/bar/baz可以指向/foo.xhtml，值bar和baz可以由@Param(pathIndex)注入.

• PrettyFaces, which is a complete URL rewrite solution. It requires an additional XML configuration file pretty-config.xml. This library is useful if you want to completely change URLs and/or want to configure redirects from old to new URLs.
• FacesViews of OmniFaces library, which makes existing URLs just extensionless by a single web.xml context param. It also supports "MultiViews" whereby path parameters can declaratively be injected in managed beans. E.g. /foo/bar/baz can point to /foo.xhtml and the values bar and baz can be injected by @Param(pathIndex).

还有 PrettyUrlPhaseListener kenai.com/projects/scales/pages/Home"rel =" nofollow noreferrer> Mojarra Scales 库，但是它是一个旧库，PrettyFaces很大程度上基于它，因此不值得付出努力.

There's also the experimental PrettyUrlPhaseListener of Mojarra Scales library, but it's an old library and PrettyFaces is largely based on it, so it's not worth the effort.
