//下述方式可以，但是不推荐
// IndexResponse i ndexResponse =

System. out. print1n("增加索引方式之Bean方式，成功否?" + indexResponse. iscreated());
}
二、使用 Bean 的方式新增索引
@Test
publicvoidtestNewAddIndexBeanWay(throws JsonProcessingException {
System. out.printIn("正式开始使用[使用Bean的方式新增索引]了...");Byte[]beanBytes=new ObjectMapper().writeValueAsBytes(newProduct(name: "Flink", author.“舍我其谁"，version: "2.3.8"); .IndexRestonse response = client.preparelndex(INDEX, TYPE, id: "2").setSource(beanBytes,XConterType.SMILE).get();
System. out.print("待新增的索引信息是: %s, es集群反馈的结果是: %s%n",new String(beanBytes),response.toString();
}
