Question

用于将文档插入弹性搜索的Java代码

Client client = new TransportClient().addTransportAddress(new InetSocketTransportAddress("127.0.0.1", 9300));
        Map<String, Object> json = new HashMap<String, Object>();
        json.put("user","dummy");
        json.put("name","dumm");
        IndexResponse indexResponse = client.prepareIndex("myindex", "mytype").setSource(json).execute().actionGet();
        System.out.println(indexResponse.toString());

通过maven添加

依赖：

 org.elasticsearch:elasticsearch:1.5.0

我正在使用1.8.0_77编译我的源代码，但仍然得到以下异常。当版本不匹配但我没有任何

时会发生此类异常

Answer 1

根本原因是找不到ElasticsearchException类，请参见异常中的最后两行。

Answer 2

elastacsearch版本是1.6.2，但您将1.5.0 jar依赖项导入maven。这可能是个问题。

Answer 3

弹性罐的两个版本之间存在冲突。 maven自动省略了1.5.0版本，因为0.5在lib中，它取决于模块的构建顺序。

RemoteTransportException无法从流Elastic Search Java API反序列化异常响应
