ES插入数据（JAVA代码）

创建ES连接

// 初始化api客户端
	public static RestHighLevelClient client = new RestHighLevelClient(
			RestClient.builder(new HttpHost(url,port, "http")));

　将需要插入的数据转化成Map<String, Object>类型

单条数据插入的方法

/**
	 * 增加索引oalogincount的当前数据
	 * @param list
	 */
	public static void addDataOaloginData(List<Map<String, Object>> list) {
		for (int i = 0; i < list.size(); i++) {
			Map<String, Object> oaloginCountVo = list.get(i);
			log.info(oaloginCountVo);
			IndexRequest request = new IndexRequest(
					INDEX,   //索引
					INDEX,     // mapping type
					oaloginCountVo.get("_id")+"");     //文档id
			oaloginCountVo.remove("_id"); //因为在插入数据时，不需要id，所以在这里将id remove掉
			request.source(oaloginCountVo);
			/*
	            request.routing("routing");  //设置routing值
	            request.timeout(TimeValue.timeValueSeconds(1));  //设置主分片等待时长
	            request.version(2);  //设置版本号
			 */
			request.setRefreshPolicy("wait_for");  //设置重刷新策略
			request.opType(DocWriteRequest.OpType.CREATE);  //操做类别
			//四、发送请求
			IndexResponse indexResponse = null;
			try {
				// 同步方式
				indexResponse = client.index(request);
			} catch(Exception e) {
				log.error("索引异常", e);
			}
			//五、处理响应
			if(indexResponse != null) {
				String index = indexResponse.getIndex();
				String type = indexResponse.getType();
				String id = indexResponse.getId();
				long version = indexResponse.getVersion();
				Result result = indexResponse.getResult();
			}
		}
	}

　　因为单条插入每一条都需要连接es，所以不太建议，建议直接批量插入

public static void addDataOaloginDataAll(List<Map<String, Object>> list) {
		BulkRequest request = new BulkRequest();
		for (int i = 0; i < list.size(); i++) {
			Map<String, Object> oaloginCountVo = list.get(i);
			String _id = (String) oaloginCountVo.get("_id");
			oaloginCountVo.remove("_id");
			 request.add(new IndexRequest(INDEX, INDEX, _id)
	                    .source(oaloginCountVo));     //文档id
			//三、发送请求    同步请求
		}
		try {
			BulkResponse bulkResponse = client.bulk(request);
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
