Elasticsearch5.x批量插入数据（Java）

先上官方示例代码：官方示例

Java代码：

// 批量插入数据
public void InsertBatch() {
    try {
        // 设置集群名称
        Settings settings = Settings.builder().put("cluster.name", "my-es-analyze").build();
        // 创建client
        TransportClient client = new PreBuiltTransportClient(settings)
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("192.168.33.5"), 9300))
                .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("192.168.33.50"), 9300));

        /* 批量操作开始 */
        BulkRequestBuilder bulkRequest = client.prepareBulk();

        InsertDomain insertDomain = null;
        String json = null;

        // 读取数据源 excel/mysql等
        List<List<String>> list = "你的数据源";

        if (list != null) {
            System.out.println("开始批量插入");
            for (int i = 0; i < list.size(); i++) {
            
                // 数据读取（略）根据自已的业务进行。
                json = JSONUtils.toJSON(inputDomain);    //转Json
                bulkRequest.add(client.prepareIndex("index", "type").setSource(json));
                
                //每一千条提交一次
                if (i % 1000 == 0) {
                    bulkRequest.execute().actionGet();
                    System.out.println("提交了：" + i);
                }
                
            }
            bulkRequest.execute().actionGet();
            System.out.println("批量插入完毕");
        }
        /* 批量操作结束 */

        // 关闭client
        client.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
