java操作[elasticsearch][]实现批量添加主要使用了bulk

代码如下：

//bulk批量操作(批量添加)
        @Test
        public void test7() throws IOException {
    //1、指定es集群  cluster.name 是固定的key值，my-application是ES集群的名称
            Settings settings = Settings.builder().put("cluster.name", "my-application").build();
            //2.创建访问ES服务器的客户端
            TransportClient client = new PreBuiltTransportClient(settings)
                    //获取es主机中节点的ip地址及端口号(以下是单个节点案例)
                                    .addTransportAddress(new TransportAddress(InetAddress.getByName("192.168.1.94"), 9300));
            
            BulkRequestBuilder builder = client.prepareBulk();
            IndexRequestBuilder request = client.prepareIndex("lib2","books","8").setSource(
                    XContentFactory.jsonBuilder()
                    .startObject()
                    .field("title","python")
                    .field("price",99)
                    .endObject()
                    );
            IndexRequestBuilder request2 = client.prepareIndex("lib2","books","9").setSource(
                    XContentFactory.jsonBuilder()
                    .startObject()
                    .field("title","VR")
                    .field("price",29)
                    .endObject()
                    );
            builder.add(request);
            builder.add(request2);
    //该方法ES默认是分片1秒钟后刷新，即插入成功后马上查询，插入的数据不能马上被查出
            BulkResponse response = builder.get();
            System.out.println(response.status());
            if(response.hasFailures()) {
                System.out.println("操作失败");
            }
        }
