用于识别Solr服务器是在云模式还是独立模式下运行的Java代码

import org.apache.solr.client.solrj.SolrClient;
import org.apache.solr.client.solrj.impl.CloudSolrClient;
import org.apache.solr.client.solrj.impl.HttpSolrClient;

public class SolrModeIdentifier {
    public static void main(String[] args) {
        String solrUrl = "http://localhost:8983/solr"; // Solr服务器的URL

        SolrClient solrClient = null;
        try {
            solrClient = new CloudSolrClient.Builder().withSolrUrl(solrUrl).build();
            System.out.println("Solr is running in cloud mode.");
        } catch (Exception e) {
            solrClient = new HttpSolrClient.Builder(solrUrl).build();
            System.out.println("Solr is running in standalone mode.");
        } finally {
            if (solrClient != null) {
                solrClient.close();
            }
        }
    }
}
