Class HttpSolrClient

java.lang.Object

org.apache.solr.client.solrj.SolrClient

org.apache.solr.client.solrj.impl.HttpSolrClient

All Implemented Interfaces:

Closeable, Serializable, AutoCloseable

public class HttpSolrClient
extends SolrClient

A SolrClient implementation that talks directly to a Solr server via HTTP There are two ways to use an HttpSolrClient: 1) Pass a URL to the constructor that points directly at a particular core

   SolrClient client = new HttpSolrClient("http://my-solr-server:8983/solr/core1");
   QueryResponse resp = client.query(new SolrQuery("*:*"));
 

In this case, you can query the given core directly, but you cannot query any other cores or issue CoreAdmin requests with this client. 2) Pass the base URL of the node to the constructor

   SolrClient client = new HttpSolrClient("http://my-solr-server:8983/solr");
   QueryResponse resp = client.query("core1", new SolrQuery("*:*"));
 

In this case, you must pass the name of the required core for all queries and updates, but you may use the same client for all cores, and for CoreAdmin requests.

getBaseURL

public String getBaseURL()

setBaseURL

public void setBaseURL(String baseURL)
