Jetty实战之 嵌入式Jetty运行web app



Jetty实战之 嵌入式Jetty运行web app

要说嵌入式运行Jetty，最常用的还应该是运行一个标准的war文件或者指定一个webapp目录。

0. 首先需要添加Jetty运行时webapp的依赖包，下面是一个完整的pom.xml文件

1. 运行标准的war文件

 

1.1 首先找一个完整的war包，这里使用了struts2自带的一个例子应用程序struts2-blank.war；

1.2 创建自己的Jetty Server启动类WebAppContextWithWarServer，其中指定了war文件的路径，并指定context路径为”/myapp”

 

  1. package com.google.code.garbagecan.jettystudy.sample6;
  3. import org.eclipse.jetty.server.Server;
  4. import org.eclipse.jetty.webapp.WebAppContext;
  6. public class WebAppContextWithWarServer {
  7.     public static void main(String[] args) throws Exception {
  8.         Server server = new Server(8080);
  10.         WebAppContext context = new WebAppContext();
  11.         context.setContextPath(“/myapp”);
  12.         context.setWar(“E:/share/test/struts2-blank.war”);
  13.         server.setHandler(context);
  15.         server.start();
  16.         server.join();
  17.     }
  18. }


1.3 运行WebAppContextWithWarServer类，然后访问// http://localhost:8080/myapp/就可以看到struts2的例子界面了。

 

 

2. 运行一个webapp目录

2.1 还是用上面的struts2-blank.war，将这个war包解压后放到一个目录下；

2.2 创建自己的Jetty Server启动类WebAppContextWithFolderServer，其中指定了webapp目录，并指定context路径为”/myapp”

 

  1. package com.google.code.garbagecan.jettystudy.sample6;
  3. import org.eclipse.jetty.server.Server;
  4. import org.eclipse.jetty.webapp.WebAppContext;
  6. public class WebAppContextWithFolderServer {
  7.     public static void main(String[] args) throws Exception {
  8.         Server server = new Server(8080);
  10.         WebAppContext context = new WebAppContext();
  11.         context.setContextPath(“/myapp”);
  12.         context.setDescriptor(“E:/share/test/struts2-blank/WEB-INF/web.xml”);
  13.         context.setResourceBase(“E:/share/test/struts2-blank”);
  14.         context.setParentLoaderPriority(true);
  15.         server.setHandler(context);
  17.         server.start();
  18.         server.join();
  19.     }
  20. }

2.3 运行WebAppContextWithFolderServer类，然后访问// http://localhost:8080/myapp/就可以看到struts2的例子界面了。
