Solrj経由でSolrにクエリを実行してみます
これが私のコードです
public class ReadFromSolr {
public static void main(String[] args) throws MalformedURLException, SolrServerException
{
String url = "http://localhost:8983/solr";
try{
SolrServer server = new CommonsHttpSolrServer(url);
ModifiableSolrParams params = new ModifiableSolrParams();
params.set("qt", "/select");
params.set("q", "name");
QueryResponse response = server.query(params);
System.out.println("response = " + response);
}
catch (MalformedURLException ex) {
ex.printStackTrace();
}
catch (SolrServerException ex) {
ex.printStackTrace();
}
}
}
そして、それは私に例外を与えます
PS。私のpeojectには次のjarがあります：
**apache - commons-logging、
* httpclient -4.2、
httpcore 4.2.1、slf4j - api 1.6.2、
apache - solr - solrj -1.4.0 ***
