curator必知必会

基本用法

	CuratorFramework client = CuratorFrameworkFactory.builder().connectString("172.16.52.191:2181,172.16.52.192:2181")
				.retryPolicy(new RetryNTimes(3, (int) TimeUnit.MILLISECONDS.toMillis(200L))).build();
		client.start();
		String path = "/harmony/domains/jasmineserver.info";
		byte[] data = client.getData().forPath(path);
		String cfg = new String(data);
		
		System.out.println("old:"+cfg);
		JSONObject json = JSON.parseObject(cfg);
		JSONObject extTags = json.getJSONObject("extTags");
		extTags.put("clientRegistryMd5", "d5e73ab2e3dd134ee2c8f808aab474a0");
		
		System.out.println("new:"+json.toJSONString());
		client.setData().forPath(path, json.toJSONString().getBytes());

		client.close();
