Java 使用Solr为我的数据库编制索引

我不知道为什么我的java代码没有被编译

我需要用solr为我的数据库编制索引

import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;



//import org.apache.lucene.index.IndexWriter;
import org.apache.solr.client.solrj.SolrServer;
import org.apache.solr.client.solrj.impl.HttpSolrServer;//   CommonsHttpSolrServer;
import org.apache.solr.client.solrj.request.ContentStreamUpdateRequest;
import org.apache.solr.client.solrj.request.AbstractUpdateRequest.ACTION;
import org.apache.solr.client.solrj.response.UpdateResponse;
import org.apache.solr.common.SolrInputDocument;
import org.apache.solr.client.solrj.impl.HttpSolrServer;


public class IndexFiles {

public static void main(String[] args) {


      HttpSolrServer server = new HttpSolrServer("http://localhost:8983/solr/");
      // i use SolrServer but it generate same error like this from httpSolrServer
      //SolrServer solr = new HttpSolrServer("http://localhost:8983/solr");  
    /*
      // TODO Auto-generated method stub
    String urlString = "http://localhost:8989/solr";
    if (args != null & args.length > 1) {
        urlString = args[1]; 
    }

    SolrServer solr = new HttpSolrServer("http://localhost:8983/solr"); //CommonsHttpSolrServer(urlString);
    try {
        indexDocs(solr, new File(args[0]));
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    */
  }
}

我用line命令启动服务器

>cd C:\Solr\solr-4.10.0\solr-4.10.0\example\solr
>java -jar start.jar

之后，我创建了一个新项目，其中包含我的类，以使用solr索引数据库

import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;



//import org.apache.lucene.index.IndexWriter;
import org.apache.solr.client.solrj.SolrServer;
import org.apache.solr.client.solrj.impl.HttpSolrServer;//   CommonsHttpSolrServer;
import org.apache.solr.client.solrj.request.ContentStreamUpdateRequest;
import org.apache.solr.client.solrj.request.AbstractUpdateRequest.ACTION;
import org.apache.solr.client.solrj.response.UpdateResponse;
import org.apache.solr.common.SolrInputDocument;
import org.apache.solr.client.solrj.impl.HttpSolrServer;


public class IndexFiles {

public static void main(String[] args) {


      HttpSolrServer server = new HttpSolrServer("http://localhost:8983/solr/");
      // i use SolrServer but it generate same error like this from httpSolrServer
      //SolrServer solr = new HttpSolrServer("http://localhost:8983/solr");  
    /*
      // TODO Auto-generated method stub
    String urlString = "http://localhost:8989/solr";
    if (args != null & args.length > 1) {
        urlString = args[1]; 
    }

    SolrServer solr = new HttpSolrServer("http://localhost:8983/solr"); //CommonsHttpSolrServer(urlString);
    try {
        indexDocs(solr, new File(args[0]));
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    */
  }
}

我得到这个错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/http/NoHttpResponseException

如何解决此问题？

听起来好像您没有将

httpclient

jar（来自dist/solrj lib）添加到类路径中

请参阅Solrj wiki页面主题：我没有commons httpclient！！您是否尝试添加了

httpclient-4.3.1.jar

？您还需要httpcore，很可能还需要commons io和slf4j。我相信这样做的目的是，您只需将solrj lib中的所有jar添加到您的类路径中，然后就可以开始比赛了。是的，我添加了httpclient-4.3.1.jar、commons-io-2.3.jar、Solr-solrj！！但他不工作！还有httpcore，对吗？正如我所说，只需将所有这些jar添加到类路径中，您就会得到最好的服务。你就是这么做的吗？
