如何配置elasticsearch 5

如何配置elasticsearch 5 TransportClient。

现在TransportClient是抽象类。我发现只有PreBuiltTransportClient，这是配置elasticsearch Client的新方法吗？

Answer 1

是的，你可以发现，在official documentation for 5.0以及

Settings settings = Settings.builder() 
    .put("cluster.name", "ElasticSearchClusterName"); 

TransportClient client = new PreBuiltTransportClient(settings) 
     .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host1"), 9300)) 
     .addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("host2"), 9300)); 

这是一文不值的PreBuiltTransportClient是pre-configured具有以下模块：

• Netty3
• Netty4
• 重新编号
• 过滤器
• 胡子

另外，还要确保你对transport神器的依赖：

<dependency> 
    <groupId>org.elasticsearch.client</groupId> 
    <artifactId>transport</artifactId> 
    <version>5.0.0-beta1</version> 
</dependency> 

Answer 2

首先下载相应的jar文件，并保持在lib文件夹中，并将它们添加到构建路径。 您可以按照下面的代码进行配置：

Settings settings = Settings.builder() 
    .put("cluster.name", "ElasticSearchClusterName") 
    //.put("client.transport.sniff", true) 
    //.put("shield.user", elasticUserName+":"+elasticPassword) 
    .build(); 

TransportClient client = new PreBuiltTransportClient(settings) 
            .addTransportAddress(new InetSocketTransportAddress(elasticHostOne, elasticTransportPort)) 
            .addTransportAddress(new InetSocketTransportAddress(elasticHostTwo, elasticTransportPort)) 
            .addTransportAddress(new InetSocketTransportAddress(elasticHostThree, elasticTransportPort));
