main方法启动

public static void main(String[] args) throws ServletException, LifecycleException {

		int port = 80;

		if (args.length == 1) {
			port = Integer.parseInt(args[0]);
		}

		// 获取项目绝对路径
		File webappPath = new File(System.getProperty("user.dir"));

		// 创建tomat容器
		Tomcat tomcat = new Tomcat();

		// 设置端口
		tomcat.setPort(port);
		
		// 设置webapp目录
		StandardContext sct = (StandardContext) tomcat.addWebapp("/", webappPath.getAbsolutePath());
		
		//web项目路径
		WebResourceRoot resourceRoot = new StandardRoot(sct);
		
		//被加载的资源文件路径
		DirResourceSet dirResourceSet = new DirResourceSet();
		
		dirResourceSet.setBase(new File("target/classes").getAbsolutePath());
		dirResourceSet.setWebAppMount("/WEB-INF/classes");
		dirResourceSet.setRoot(resourceRoot);
		dirResourceSet.setInternalPath("/");
		
		//把项目设置到webapp中
		resourceRoot.addPreResources(dirResourceSet);
		sct.setReloadable(false);
		sct.setResources(resourceRoot);

		tomcat.start();
		System.out.println("Tomcat已在本地" + port + "端口启动!");
		tomcat.getServer().await();
