要說嵌入式執行Jetty，最常用的還應該是執行一個標準的war檔案或者指定一個webapp目錄。

0. 首先需要新增Jetty執行時webapp的依賴包，下面是一個完整的pom.xml檔案

<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"> <modelVersion>4.0.0</modelVersion

1.1 首先找一個完整的war包，這裡使用了struts2自帶的一個例子應用程式struts2-blank.war；

1.2 建立自己的Jetty Server啟動類WebAppContextWithWarServer，其中指定了war檔案的路徑，並指定context路徑為"/myapp"

package com.google.code.garbagecan.jettystudy.sample6;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.webapp.WebAppContext;public class WebAppContextWithWarServer { public static void main(String[] args) throws Exception {  Server server = new Server(8080);  WebAppContext context = new WebAppContext();  context.setContextPath("/myapp");  context.setWar("E:/share/test/struts2-blank.war");  server.setHandler(context);  server.start();  server.join(); }}

2. 執行一個webapp目錄

2.1 還是用上面的struts2-blank.war，將這個war包解壓後放到一個目錄下；

2.2 建立自己的Jetty Server啟動類WebAppContextWithFolderServer，其中指定了webapp目錄，並指定context路徑為"/myapp"

package com.google.code.garbagecan.jettystudy.sample6;import org.eclipse.jetty.server.Server;import org.eclipse.jetty.webapp.WebAppContext;public class WebAppContextWithFolderServer { public static void main(String[] args) throws Exception {  Server server = new Server(8080);  WebAppContext context = new WebAppContext();  context.setContextPath("/myapp");  context.setDescriptor("E:/share/test/struts2-blank/WEB-INF/web.xml");  context.setResourceBase("E:/share/test/struts2-blank");  context.setParentLoaderPriority(true);  server.setHandler(context);  server.start();  server.join(); }}
