RemoteTransportException無法反序列化來自流Elastic Search Java API的異常響應

Question

用於將文檔插入彈性搜索的Java代碼

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());  

響應： http：// localhost：9200 / _nodes？jvm = true

"pid": ​6797,
"version": "1.8.0_77",
"vm_name": "Java HotSpot(TM) 64-Bit Server VM",
"vm_version": "25.77-b03",
"vm_vendor": "Oracle Corporation",

http：// localhost：9200的響應：

{

    "status": ​200,
    "name": "Sin",
    "cluster_name": "elasticsearch",
    "version": 

    {
        "number": "1.6.2",
        "build_hash": "622039121e53e5f520b5ff8720fdbd3d0cb5326b",
        "build_timestamp": "2015-07-29T09:24:47Z",
        "build_snapshot": false,
        "lucene_version": "4.10.4"
    },
    "tagline": "You Know, for Search"

}

通過Maven添加的依賴

 org.elasticsearch:elasticsearch:1.5.0

我正在使用1.8.0_77進行編譯以編譯我的源代碼，但仍然收到以下異常。 當版本不匹配但我沒有任何版本時，會發生這種類型的異常

Answer 1

根本原因是找不到ElasticsearchException類，請參閱異常中的最后兩行。

Answer 2

elastacsearch版本是1.6.2，但是您將1.5.0 jar依賴項導入到maven中。 這也許是問題所在。

Answer 3

彈性罐的兩個版本之間存在沖突。 maven自動忽略了1.5.0版本，因為lib中存在0.5，它取決於模塊的構建順序。
