J2EE打造可执行war包

1. 使用Jetty为嵌入式服务器； 2. 使用ant将web应用打包为runnable.war; 3. 命令行java -jar runnable.war启动web服务。

1.  下载jetty

注意： Jetty 9.x 需要 JDK 1.7 支持。下表是Jetty各版本状态一览。

下载地址： http://download.eclipse.org/jetty/

2.   启动类

package net.codaview;    import java.io.File;  import java.net.URL;  import java.security.ProtectionDomain;    import org.eclipse.jetty.server.Server;  import org.eclipse.jetty.webapp.WebAppContext;    public class EmbeddedServer {        public static void main(String[] args) throws Exception {          int port = Integer.parseInt(System.getProperty("port", "8080"));          Server server = new Server(port);            ProtectionDomain domain = EmbeddedServer.class.getProtectionDomain();          URL warLocation = domain.getCodeSource().getLocation();            WebAppContext webapp = new WebAppContext();          webapp.setContextPath("/");          webapp.setDescriptor(warLocation.toExternalForm() + "/WEB-INF/web.xml");          webapp.setServer(server);          webapp.setWar(warLocation.toExternalForm());          String tempDir = new File(warLocation.getPath()).getParent() + "/tmp";          webapp.setTempDirectory(new File(tempDir));            server.setHandler(webapp);          server.start();          server.join();      }  }

3.   ant脚本

4. 运行
