使用java命令重启tomcat

public static void restartMyTomcat() {
		String location=ConfigUtil.getRestartLocation();

		createCmdFile(location);
		executeCmd(location);

	}

	private static void executeCmd(String location) {
		System.out.println(location);
		Runtime run = Runtime.getRuntime();
		try {
			Process ps = run.exec("" + location + "\\bin\\restart.bat");
			//我很奇怪  下面的代码去掉的话 tomcat的黑框就不能出现
			BufferedReader br = new BufferedReader(new InputStreamReader(
					ps.getInputStream(), "GBK"));// 注意中文编码问题
			String line;
			while ((line = br.readLine()) != null) {
				System.out.println("StartedLog==>" + line);
			}
			br.close();
		} catch (Exception e) {
			e.printStackTrace();
		}

	}

	private static void createCmdFile(String location) {
		File f = new File(location + "\\bin\\restart.bat");
		try {
			FileWriter fw = new FileWriter(f);
			BufferedWriter bw = new BufferedWriter(fw);
			 //下面的必须加上
			bw.write("set CATALINA_HOME=" + location);
			bw.newLine();
			bw.write("call " + f.getParent() + "\\bin\\shutdown.bat");
			bw.newLine();
			bw.write(" ping 127.0.0.1 -n 5  1>nul ");
			bw.newLine();
			bw.write("call " + f.getParent() + "\\bin\\startup.bat ");

			bw.close();
			fw.close();
		} catch (Exception e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}

	}
