可运行war包，命令行启动war包

如果你用过hudson，肯定对它的启动方式印象深刻，它既可以用 java -jar *.war来启动，也可以放到web容器中启动。

这次在项目中也用到了这种方式，在这里总结一下，

内置了jetty作为启动容器，

启动类：

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 CompareLuncher {
	public static void main(String[] args) throws Exception {
		String currentPath=new File("").getAbsolutePath();
		//如果没有work目录，则创建,jetty默认解压路径
		File work=new File(currentPath+"\\work");
		if(!work.exists()){
			work.mkdir();
		}
		Server server =null;
		Integer port=8090;
		server=new Server(port);
		ProtectionDomain domain = CompareLuncher.class.getProtectionDomain();
		URL location = domain.getCodeSource().getLocation();
		WebAppContext webapp = new WebAppContext();
		webapp.setContextPath("/");
		webapp.setWar(location.toExternalForm());
		server.setHandler(webapp);
		server.start();
		server.join();
		
		//启动部署包的时候可以用这个
		// // Server server = new Server(8080);
		// // WebAppContext context = new WebAppContext();
		// // context.setContextPath("/compare");
		// // context.setWar("F:/compare.war");
		// // server.setHandler(context);
		// // server.start();
		// // server.join();

		//eclipse 测试的时候启用如下代码,debug模式下可以直接看到修改效果
//		 Server server = new Server(8090);
////		 
//		 ResourceHandler resourceHandler = new ResourceHandler();  
//	     resourceHandler.setDirectoriesListed(true);  
//	        
//		 server.setSendServerVersion(true);
//		 server.setStopAtShutdown(true);
//		 server.setHandler(getWebAppContext());
//		 server.start();
//		 server.join();

	}

	private static WebAppContext getWebAppContext() {

		String path = CompareLuncher.class.getResource("/").getFile()
				.replaceAll("/target/(.*)", "")
				+ "/src/main/webapp";
//		System.out.println(path);
		String path2 = new File("").getAbsolutePath() + "\\src\\main\\webapp";
		// System.out.println();

		return new WebAppContext(path2, "/");
	}
}

 最后 在 workspace/项目名的根文件夹下执行：mvn clean install，再到target文件夹下找到 项目名称.war

用 java -jar  名字.war 即可启动

运行 mvn clean install 出现报错信息

> An Ant BuildException has occured

完整报错信息

> [ERROR] Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (main-class-placement) on project pdfcompare: An Ant BuildException has occured: C:\www\dotku.github.io\tech\java-maven\demo-war-running\target\classes does not exist.

看看...?
