如何在URL中使用.jsf扩展名? [英] How to use .jsf extension in URLs?

问题描述

我正在开发JSF 2 Web应用程序.对于威信，我希望每个URL都以.jsf扩展名结尾.现在，它以.xhtml结尾.如果将其直接更改为Web浏览器地址栏中的.jsf，则会显示HTTP 500错误.

I'm developing a JSF 2 web application. For prestige purpouses I would like that every URL ends with .jsf extension. Now it ends with .xhtml. If I change it directly to .jsf in web browser address bar, then a HTTP 500 error is shown.

如何将其设置为.jsf?

推荐答案

JSF页面的URL模式由web.xml中FacesServlet的<servlet-mapping>指定.正如您所提到的，.xhtml可以正常工作，您显然已对其进行了如下配置:

The URL pattern of JSF pages is specified by <servlet-mapping> of the FacesServlet in web.xml. As you mentioned that .xhtml works fine, you have apparently configured it as follows:

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>      
</servlet-mapping>

您需要相应地更改<url-pattern>以获得所需的虚拟URL扩展名.

You need to change the <url-pattern> accordingly to get the desired virtual URL extension.

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>      
</servlet-mapping>

实际上，这是您需要更改以实现具体功能要求的所有内容.

That's all you need to change in order to achieve the concrete functional requirement, really.

但是，这将带来一个安全问题.现在，当将URL中的扩展名从.jsf更改为.xhtml时，最终用户可以看到原始的Facelets文件源代码.您可以通过在web.xml上添加以下安全约束来防止这种情况:

However, this puts a security problem open. The enduser can now see the raw Facelets file source code when changing the extension in the URL back from .jsf to .xhtml. You can prevent this by adding the following security constraint to web.xml:

<security-constraint>
    <display-name>Restrict access to Facelets source code.</display-name>
    <web-resource-collection>
        <web-resource-name>Facelets</web-resource-name>
        <url-pattern>*.xhtml</url-pattern>
    </web-resource-collection>
    <auth-constraint/>
</security-constraint>
