在Apache Tomcat上運行JSF項目

如何在Tomcat上共享午餐JSP項目？我複製WebContent文件夾到webapp文件夾的Apache，但它無法找到我的jsp頁面，但如果我將jsp更改爲jsf（index.jsf）可以正常工作。我怎麼解決這個問題？在Apache Tomcat上運行JSF項目

的web.xml：

這不是問題。這是預期的行爲。你只是誤解了基本的Servlet API的工作原理。你已經配置了JSF標準FacesServlet聽匹配/faces/*網址，並已配置的Apache MyFaces的具體MyFacesServlet聽匹配*.jsf和*.faces網址。

要獲得JSF運行，必須通過匹配FacesServlet的映射的URL打開瀏覽器頁面。既然你已經一個index.jsp文件和你的上下文路徑是Graph，並且已經在三個不同的URL模式配置了兩個JSF的servlet，您可以通過以下網址打開JSP的事實：

http://localhost:8080/Graph/faces/index.jsp（所調用FacesServlet）
http://localhost:8080/Graph/index.jsf（調用MyFacesServlet）
http://localhost:8080/Graph/index.faces（調用MyFacesServlet）

表示您的配置不必要的過於複雜。擺脫MyFacesServlet條目及其所有關聯的URL映射（servlet名稱爲faces）。只要堅持標準FacesServlet並使用其映射，或改爲改爲它。我個人推薦使用*.jsf。

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

然後你可以通過http://localhost:8080/Graph/index.jsf打開頁面。

無關的具體問題，您welcome-file不會這樣的。 Tomcat會在該頁面上發出HTTP 404錯誤（頁面/資源未找到）。你需要指定index.jsf爲welcome-file和在同一文件夾提供一個具體的，但空index.jsf文件作爲index.jsp。通過這種方式，Tomcat將被愚弄，該文件存在並通過調用http://localhost:8080/Graph來顯示頁面。

如果您關注的是，它是可以打開通過其*.jsp擴展JSF頁面，這將導致一個RuntimeException: FacesContext not found，你反倒沒有一個JSP文件，該文件是送達普通的香草，那麼你可以限制直接訪問JSP文件由以下安全約束在web.xml：

<security-constraint> 
    <display-name>Restrict direct access to JSP files</display-name> 
    <web-resource-collection> 
     <web-resource-name>JSP files</web-resource-name> 
     <url-pattern>*.jsp</url-pattern> 
    </web-resource-collection> 
    <auth-constraint /> 
</security-constraint>

（在JSF 2.0，這是順便說不需要了，默認視圖技術的Facelets有可能在FacesServlet上只是*.xhtml地圖，這與Facelets文件的默認擴展名相同）
