How do I configure JSF url mappings without file e

问题:

Most tutorials propose a default JSF configuration similar to the following web.xml:

<context-param>
    <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
    <param-value>.xhtml</param-value>
</context-param>


<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>

With this configuration the corresponding *.xhtml files in my webapp are only found by the Faces Servlet if the corresponding URLs ends with the file extension .jsf (e.g. http://localhost/welcome.jsf). Is it possible to configure web.xml so URLs that do not end with .jsf are also processed as JSF pages using the same *.xhtml files?

In other words I would like to have URLs that do not depend on the server side implementation.

You can use Filter to hide this extension and make your URL SEO friendly,One of such implementation of Filter is Pretty Filter.

For example: If you need http://host:port/yourapp/login to resolve with your login.xhtml then in pretty filter configure following way

<url-mapping id="login">
    <pattern> /login </pattern>
    <view-id> /legacy/user/login.jsf </view-id>
</url-mapping>

Have a look at two min video tutorial

you can create url mapping like this create faces-config.xml file in WEB-INF folder

<?xml version="1.0" encoding="ISO-8859-1"?>

<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
   http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd"
              version="1.2">

   <navigation-rule>
        <from-view-id>/jsf/demoapp</from-view-id>
        <navigation-case>
            <from-outcome>demoapp</from-outcome>
            <to-view-id>/demoapp.xhtml</to-view-id>
        </navigation-case>
   </navigation-rule>


</faces-config>

in web.xml you have to do 2 entries

    <servlet>
        <servlet-name>jsfServlets</servlet-name>
        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>jsfServlets</servlet-name>
        <url-pattern>/jsf/*</url-pattern>
    </servlet-mapping>
