无法通过JAVA连接到Solr应用程序

我在这个论坛上搜索了这个问题，发现很多答案，但他没有答案解决我的问题我想通过Java连接到Solr应用程序（版本6.1.0），但它给我错误。我的代码是：无法通过JAVA连接到Solr应用程序

import org.apache.solr.client.solrj.SolrClient; 
import org.apache.solr.client.solrj.SolrQuery; 
import org.apache.solr.client.solrj.impl.HttpSolrClient; 
import org.apache.solr.client.solrj.response.QueryResponse; 
public class solrConnection { 
    public void solrConnectionTest() { 
    try{ 
    String baseURL = "http://"IP-Address":8983/solr/#/test1/test2"; 
    @SuppressWarnings("deprecation") 
    SolrClient solr = new HttpSolrClient(baseURL); 
    SolrQuery query = new SolrQuery(":"); 
    query=new SolrQuery(); 
    query.set("qt", "/select"); 
    query.set("q", "sample test"); 
    query.set("wt", "json"); 
    QueryResponse response = solr.query(query); 
    System.out.println("Response is : "+response); 
    System.out.println("Program executed successfully"); 
    }catch(Exception e){ 
     e.printStackTrace(); 
    } 
    } 
} 

Error is: 


org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://"IP-Address":8983/solr/#/test1/test2: Expected mime type application/octet-stream but got text/html. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

你有没有提到集合名称。？ 'http：//“IP地址”：8983/solr/collectionname' – vinod

我没有完全理解你。我给了URL“http：//”IP地址“：8983/solr”。 – SachinB

https://cwiki.apache.org/confluence/display/solr/Using+SolrJ – vinod

我可以连接到Solr现在使用HttpURLConnection类。以下是我的代码正在运行成功。

InputFileDeclared input = new InputFileDeclared(); 
String url = "My URL"; 
private void sendGet() throws Exception {  
URL obj = new URL(url); 
HttpURLConnection con = (HttpURLConnection) obj.openConnection(); 
     // optional default is GET 
     con.setRequestMethod("GET"); 
     int responseCode = con.getResponseCode(); 
     System.out.println("\nSending 'GET' request to URL : " + url); 
     System.out.println("Response Code : " + responseCode); 
     BufferedReader in = new BufferedReader(
       new InputStreamReader(con.getInputStream())); 
     String inputLine; 
     StringBuffer response = new StringBuffer(); 
     while ((inputLine = in.readLine()) != null) { 
      response.append(inputLine); 
     } 
     in.close(); 
     //print result 
     String data = response.toString(); 
     System.out.println(response.toString()); 
}
