elasticsearch java插入索引批量操作

1.單條所以插入
//第一個參數：索引名；第二個參數：索引類型；第三個參數：索引ID(相同的id時修改數據，默認為隨機字符串)
IndexResponse indexResponse = client.prepareIndex("twitter", "json","1").setSource(json).get();

2.批量插入
BulkRequestBuilder bulkRequest = client.prepareBulk();

IndexRequest request = client.prepareIndex("twitter", "json","1").setSource(json).request();
IndexRequest request2 = client.prepareIndex("twitter", "json","2").setSource(json2).request();

bulkRequest.add(request);
bulkRequest.add(request2);

bulkRequest.execute().actionGet();
