五、在myeclipse中查询与添加索引实例

public class SolrjPopulator {
public static void main(String[] args) throws IOException, SolrServerException {

HttpSolrServer server = new HttpSolrServer("http://localhost:8083/solr");

//======进行用户验证，因为tomcat中设定了用户验证，所以为了能连接服务器必需要验证用户，否则不能连通服务器
DefaultHttpClient m_client =(DefaultHttpClient)server.getHttpClient();
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("admin","admin");
m_client.addRequestInterceptor(new PreemptiveAuthInterceptor(),0);
(((DefaultHttpClient)m_client).getCredentialsProvider()).setCredentials(new AuthScope("localhost",8083), credentials);
//============
for (int i = 0; i < 3; i++) {
SolrInputDocument doc = new SolrInputDocument();
doc.addField("age", "27");
doc.addField("id", "5"+i);
doc.addField("name", "小刚子"+i);
server.add(doc);
//			if (i == 2)
server.commit(); // periodically flush
}
server.commit();
}
}

public class SolrJSearcher {
public static void main(String[] args) throws MalformedURLException, SolrServerException {
HttpSolrServer solr = new HttpSolrServer("http://localhost:8083/solr/core0");

//====进行用户验证，因为tomcat中设定了用户验证，所以为了能连接服务器必需要验证用户，否则不能连通服务器
DefaultHttpClient m_client =(DefaultHttpClient)solr.getHttpClient();
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("admin","admin");
m_client.addRequestInterceptor(new PreemptiveAuthInterceptor(),0);
(((DefaultHttpClient)m_client).getCredentialsProvider()).setCredentials(new AuthScope("localhost",8083), credentials);
//======
ModifiableSolrParams params = new ModifiableSolrParams();
//params.set("q", "name:李*人");

params.set("defType", "dismax");
params.set("hl", "true");

//        params.set("start", "0");

QueryResponse response = solr.query(params);
SolrDocumentList results = response.getResults();
for (int i = 0; i < results.size(); ++i) {
System.out.println(results.get(i));
}
}
}

public class PreemptiveAuthInterceptor implements HttpRequestInterceptor {

public void process(HttpRequest request,
