玩笑客户端/ ElasticSearch集群信息

Question

我用开玩笑的客户端在Java应用程序连接到ElasticSearch集群，现在我想找到如何让集群信息像这样与笑话API的信息：

{ 
"name" : "", 
"cluster_name" : "", 
"version" : { 
"number" : "2.3.2", 
"build_hash" : "", 
"build_timestamp" : "", 
"build_snapshot" : , 
"lucene_version" : " 
}, 
"tagline" : "You Know, for Search" 
}

我花了一点时间阅读jest源代码并获得结果。请看下面的代码：

Jest.java

import io.searchbox.client.JestClient; 
import io.searchbox.client.JestClientFactory; 
import io.searchbox.client.JestResult; 
import io.searchbox.client.config.HttpClientConfig; 
import java.io.IOException; 
import java.util.logging.Level; 
import java.util.logging.Logger; 

/**

* @author Vladislav Kislyi <vladislav.kisliy@gmail.com> 
*/ 
public class Jest { 

    public static void main(String[] args) throws IOException { 
     // Construct a new Jest client according to configuration via factory 
     JestClientFactory factory = new JestClientFactory(); 
     factory.setHttpClientConfig(new HttpClientConfig.Builder("http://localhost:9200") 
       .multiThreaded(true) 
       .build()); 
     JestClient client = factory.getObject(); 

     GetStartPage getStartPage = new GetStartPage.Builder().build(); 
     try { 
      JestResult execute = client.execute(getStartPage); 
      System.out.println("result =" + execute.getJsonString()); 
     } catch (IOException ex) { 
      Logger.getLogger(Jest.class.getName()).log(Level.SEVERE, null, ex); 
     } 

    } 
} 

和GetStartPage.java

import io.searchbox.action.AbstractAction; 
import io.searchbox.action.GenericResultAbstractAction; 

public class GetStartPage extends GenericResultAbstractAction { 

    protected GetStartPage(Builder builder) { 
     super(builder); 
     setURI(buildURI()); 
    } 

    protected String buildURI() { 
     return super.buildURI() + "/?pretty"; 
    } 

    @Override 
    public String getRestMethodName() { 
     return "GET"; 
    } 

    public static class Builder extends AbstractAction.Builder<GetStartPage, Builder> { 

     @Override 
     public GetStartPage build() { 
      return new GetStartPage(this); 
     } 
    } 
}
