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：

Java代码

1.  import java.io.File;  
2.  import java.net.URL;  
3.  import java.security.ProtectionDomain;

11.         //如果没有work目录，则创建,jetty默认解压路径  
12.         File work=new File(currentPath+"\\\\work");  
13.         if(!work.exists())\{  
14.             work.mkdir();  
15.         \}

51.     private static WebAppContext getWebAppContext() \{  
52.   
53.         String path = CompareLuncher.class.getResource("/").getFile()  
54.                 .replaceAll("/target/(.\*)", "")  
55.                 + "/src/main/webapp";

59.   
60.         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
