使用SolrJ客戶端連接器連接到Solr 1.4 3.6

Question

如何使用SolrJ 3.6連接器連接到使用Basic Auth配置的Solr 1.4搜索服務器？

Answer 1

基於該instructions on using SolrJ：

取爲例如相關的依賴關係使用maven：

<dependency> 
     <groupId>org.apache.solr</groupId> 
     <artifactId>solr-solrj</artifactId> 
     <version>3.6.1</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.httpcomponents</groupId> 
     <artifactId>httpcore</artifactId> 
     <version>4.2.2</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.httpcomponents</groupId> 
     <artifactId>httpclient</artifactId> 
     <version>4.2.1</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.httpcomponents</groupId> 
     <artifactId>httpmime</artifactId> 
     <version>4.1.2</version> 
    </dependency> 

的示例應用程序連接到Solr 1.4使用SolrJ 3.6與最新版的Apache HTTP組件HTTP客戶端進行談判基本身份驗證：

import java.util.Iterator;

/**

    { 
     String url = "https://localhost:8080/solr/"; 
     String httpAuthUser = "solr_admin"; 
     String httpAuthPass= "somePassword"; 
      // Configure latests Apache Http Components http client 
     HttpClient httpClient = new DefaultHttpClient(); 
     if (httpAuthUser != null && httpAuthPass != null) { 
      AbstractHttpClient client = (AbstractHttpClient) httpClient; 
      App a = new App(); 
      client.addRequestInterceptor(a.new PreEmptiveBasicAuthenticator(httpAuthUser, httpAuthPass)); 
      } 
     // Configure XMLResponseParser as standard javabin parser does not work with 1.4 
     SolrServer solr = new HttpSolrServer(url, httpClient, new XMLResponseParser()); 
     // Test adding some data 
     SolrInputDocument document = new SolrInputDocument(); 
     document.addField("id", "552199"); 
     document.addField("name", "Gouda cheese wheel"); 
     document.addField("price", "49.99"); 
     UpdateResponse uresponse = solr.add(document); 
     System.out.println("UpdateResponse"+uresponse.getStatus()); 
     solr.commit(); 

     // Query for the data just added 
     SolrQuery parameters = new SolrQuery(); 
     parameters.set("q", "*"); 
     QueryResponse response = solr.query(parameters); 
     SolrDocumentList list = response.getResults(); 
     Iterator<SolrDocument> si = list.iterator(); 
     System.out.println("Solr document"+list.getNumFound()); 
     while(si.hasNext()){ 
      System.out.println("Solr document"+si.next().toString()); 
     } 
    } 


    protected class PreEmptiveBasicAuthenticator implements HttpRequestInterceptor { 
      private final UsernamePasswordCredentials credentials; 

      public PreEmptiveBasicAuthenticator(String user, String pass) { 
      credentials = new UsernamePasswordCredentials(user, pass); 
      } 

      public void process(HttpRequest request, HttpContext context) 
       throws HttpException, IOException { 
      request.addHeader(BasicScheme.authenticate(credentials,"US-ASCII",false)); 
      } 
     }
