Java弹性搜索客户端始终为null [英] Java elasticsearch client always null

问题描述

最近我已经从弹性搜索1.7到2.0，我注意到你设置客户端的方式已经改变了。我浏览了文档，由于某种原因，客户端始终为空。我想知道我是否正确设置。

这是我的代码：

 code> Client client = null; 
 
 try {
 client = TransportClient.builder（）。build（）。addTransportAddress（new InetSocketTransportAddress（InetAddress.getByName（localhost），9300））; 
} catch（Exception e）{
 Logger.log（e）; 
} finally {
 client.close（）; 
 try {
 conn.close（）; 
} catch（SQLException e）{
 Logger.log（e）; 
} 
} 
  

解决方案

在评论中注意到，但更详细一点：Elasticsearch 2.0使用Guava 18.0（请参阅 https://github.com/弹性/ elasticsearch /拉/ 7593 ）。所以要修复错误，如 java.lang.NoSuchMethodError：com.google.common.util.concurrent.MoreExecutors.directExecutor（）Ljava / util / concurrent / Executor; ，确保使用Guava 18.0作为依赖，而不是其他版本。

I've recently made the switch from elasticsearch 1.7 to 2.0 and I noticed the way you setup the client has changed. I went through the documentation and for some reason the client is always null. I was wondering if I have set it up correctly.

Here is my code:

    Client client = null;

    try {
        client = TransportClient.builder().build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));
    } catch (Exception e) {
        Logger.log(e);
    } finally {
        client.close();
        try {
            conn.close();
        } catch (SQLException e) {
            Logger.log(e);
        }
    }

解决方案

As noted in the comments, but a little bit more in detail: Elasticsearch 2.0 uses Guava 18.0 (see https://github.com/elastic/elasticsearch/pull/7593). So to fix errors like java.lang.NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors.directExecutor()Ljava/util/concu‌rrent/Executor;, make sure to use Guava 18.0 as dependency and not other versions.
