java操作elasticsearch实现批量添加数据（bulk）

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");

        }

    }
