Я использую Solr 7.5 Server, и я использовал External Zookeeper. Когда я просматриваю, используя Solr Admin UI, он запрашивает у меня аутентификацию.
Для клиента Java я использовал приведенный ниже код
BasicAuthSolrClientCache bs = new BasicAuthSolrClientCache("solr", "SolrRocks");
CloudSolrClient solrCloudClient = bs.getCloudSolrClient(zkHost);
solrCloudClient.setDefaultCollection("sample");
SolrInputDocument doc = new SolrInputDocument();
doc.addField("cat", "book");
doc.addField("id", "book-1");
doc.addField("name", "The Legend of the Hobbit part 1");
solrCloudClient.add(doc);
solrCloudClient.commit();
solrCloudClient.close();
BasicAuthSolrClientCache.java
public class BasicAuthSolrClientCache extends SolrClientCache {
private static final Logger log =
LoggerFactory.getLogger(MethodHandles.lookup().lookupClass());
private final Map<String, SolrClient> solrClients = new HashMap<>();
private final String username;
private final String password;
public BasicAuthSolrClientCache(String username, String password) {
this.username = username;
this.password = password;
}
@Override
public synchronized CloudSolrClient getCloudSolrClient(String zkHost) {
CloudSolrClient client;
if (solrClients.containsKey(zkHost)) {
client = (CloudSolrClient) solrClients.get(zkHost);
} else {
client = new CloudSolrClient.Builder()
.withZkHost(zkHost)
.withHttpClient(getHttpClient())
.build();
client.connect();
solrClients.put(zkHost, client);
}
return client;
}
@Override
public synchronized HttpSolrClient getHttpSolrClient(String host) {
HttpSolrClient client;
if (solrClients.containsKey(host)) {
client = (HttpSolrClient) solrClients.get(host);
} else {
client = new HttpSolrClient.Builder(host)
.withHttpClient(getHttpClient())
.build();
solrClients.put(host, client);
}
return client;
}
@Override
public synchronized void close() {
for(Map.Entry<String, SolrClient> entry : solrClients.entrySet()) {
try {
entry.getValue().close();
} catch (IOException e) {
log.error("Error closing SolrClient for " + entry.getKey(), e);
}
}
solrClients.clear();
}
private HttpClient getHttpClient() {
CredentialsProvider provider = new BasicCredentialsProvider();
UsernamePasswordCredentials credentials = new
UsernamePasswordCredentials(this.username, this.password);
provider.setCredentials(AuthScope.ANY, credentials);
return
HttpClientBuilder.create().setDefaultCredentialsProvider(provider).
build();
}
}
Но это дает исключение, как показано ниже,
Исключение в потоке "main"org.apache.solr.
