Java之綁定ES集羣

下面來繼續記錄並分享ES相關：

下面來分享一個連接ES集羣的方法，如下所示：

/**
* create by wxy_jdhk
*/
public class ElasticSearchUtils {
	//json格式 數據綁定demo1
	public String createJsonDemoOne() {
		String json = "{" + 
				"\"user\":\"kimchy\"," +
				"\"postDate\":\"2013-01-30\"," + 
				"\"message\":\"trying out Elasticsearch\"" + 
				"}";
			return json;
	}
	
	//json格式 數據綁定demo2
	public Map<String, Object> createJsonDemoTwo() {
		Map<String, Object> json = new HashMap<String, Object>();
		json.put("user", "kimchy");
		json.put("postDate", new Date());
		json.put("message", "trying out Elasticsearch");
		return json;
	}
	
	//json格式 數據綁定demo3
	
	//綁定集羣
	public void connectionCluster() {
		//bind cluster
		Settings settings = Settings.builder()
		        .put("cluster.name", "elasticsearch").build();
		TransportClient client = new PreBuiltTransportClient(settings);
		//Jackson Databind
		//instance a json mapper
		ObjectMapper mapper = new ObjectMapper(json, json, false, null, null, null, null, settings);
		client.close();
	}
