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");
        }
    }
