在系统运行过程中，出现系统进程退出，整个消失的情况。使用JAVA程序监控并守护其运行。

	public void doTask_activemq() throws InterruptedException {
		/**activemq**/
		try {
			Process process1 = Runtime.getRuntime().exec("ps -ef|grep java |grep activemq");
			
			String result = getProcessResult(process1);
			
			if (StringUtils.isBlank(result) 
			 || !result.contains("/home/abc/apache-activemq-5.11.1/bin/activemq.jar")) {
				logger.info("@@@activemq进程挂了，重启activemq...");
				Runtime.getRuntime().exec("/home/abc/apache-activemq-5.11.1/bin/activemq start");
			} else {
				logger.info("activemq进程正常运行...");
			}
		} catch (IOException e) {
			e.printStackTrace();
		}
	
	}


	private String getProcessResult(Process process1) throws IOException, InterruptedException {
		process1.waitFor();

		InputStream is = process1.getInputStream();
		
		BufferedReader reader = new BufferedReader(new InputStreamReader(is));
		String line;
		StringBuffer sb = new StringBuffer();
		while ((line = reader.readLine()) != null) {
			sb.append(line);
		}
		is.close();
		reader.close();
		process1.destroy();
		
		return sb.toString();
