Question

已解决：我使用了错误的命名空间，请参阅此帖后的解释。

当尝试运行嵌入式tomcat并导航到jsf页面时，jsf标记只是简单地呈现在页面中，并且它们不会被执行。

编辑：我将这个maven项目添加到了

https://github.com/traugott/embedded-tomcat-example-jsf-dont-work.git

只需使用

克隆它

git clone https://github.com/traugott/embedded-tomcat-example-jsf-dont-work.git

创建tomcat嵌入式服务器的文件是：

package launch;

import java.io.File;
import org.apache.catalina.Context;
import org.apache.catalina.core.AprLifecycleListener;
import org.apache.catalina.core.StandardServer;
import org.apache.catalina.startup.Tomcat;

public class Main {

  public static void main(String[] args) throws Exception {

    String webappDirLocation = "src/main/webapp/";
    Tomcat tomcat = new Tomcat();
    tomcat.setPort(8080);

    tomcat.setBaseDir(".");
    tomcat.getHost().setAppBase(".");
    tomcat.setSilent(false);

    // Add AprLifecycleListener
    StandardServer server = (StandardServer) tomcat.getServer();
    AprLifecycleListener listener = new AprLifecycleListener();
    server.addLifecycleListener(listener);

    Context ctx = tomcat.addWebapp("/", new File(webappDirLocation).getAbsolutePath());
    Tomcat.addServlet(ctx, "jsf_servlet", "javax.faces.webapp.FacesServlet");
    ctx.addServletMapping("*.xhtml", "jsf_servlet");
    tomcat.start();
    tomcat.getServer().await();
  }
}

web.xml（在src / main / webapp / WEB-INF下）是：

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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-app_2_5.xsd">

  <display-name>Test</display-name>

  <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>*.xhtml</url-pattern>
  </servlet-mapping>

  <welcome-file-list>
    <welcome-file>index.xhtml</welcome-file>
  </welcome-file-list>

  <listener>
     <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
  </listener>   

</web-app>

index.xhtml是（在src / main / webapp /下）：

<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
  <h:head>
  </h:head>
  <h:body>
    <h:outputText value="Hallo JSF-Tomcat-Embedded-Welt"/>
  </h:body>
</html>

最后是pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

我不知道问题出在哪里，但我想我错过了什么。

有人可以帮忙吗？

Answer 1

我去了。我使用了错误的命名空间。在上面的问题中，命名空间仍然是错误的（它是jsf 2.2的命名空间）。我上传了一个带有正确命名空间的index.xhtml到github。

对于pom.xml-File中给出的版本，jsf html标记的名称空间必须是： http://java.sun.com/jsf/html

嵌入式Tomcat不执行jsf页面
