Solr 将 CommonsHttpSolrServer 更改为 HttpSolrServer

Question

对于 solr 3.5 中的基本身份验证，我使用以下代码，

String url = "http://192.168.192.11:8080/solr/FormResponses";
CommonsHttpSolrServer server = new CommonsHttpSolrServer( url );
String username = "user";
String password = "user123";
Credentials defaultcreds = new UsernamePasswordCredentials(username, password);
server.getHttpClient().getState().setCredentials(AuthScope.ANY, defaultcreds);
server.getHttpClient().getParams().setAuthenticationPreemptive(true);

在 solr 4.0 CommonsHttpSolrServer不可用，所以我想用 HttpSolrServer .谁能帮我解决这个问题？

Answer 1

更改代码如下:

import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.solr.client.solrj.impl.HttpSolrServer;

String url = "http://192.168.192.11:8080/solr/FormResponses";
HttpSolrServer server = new HttpSolrServer( url );
DefaultHttpClient client = (DefaultHttpClient) server.getHttpClient();

UsernamePasswordCredentials defaultcreds = new UsernamePasswordCredentials("user", "user123");
client.getCredentialsProvider().setCredentials(AuthScope.ANY, defaultcreds);

对于 server.getHttpClient().getParams().setAuthenticationPreemptive(true)在 HttpClient 4 中，您可以使用描述的解决方案 here .
