我是MOngoDB + Java配置的新手.我试图从远程mongodb服务器到Java应用程序的连接.我想使用GSSAPI机制来连接mongotemplate.下面的代码已成功执行.下面的代码来自我的配置文件.
List<ServerAddress> serverAddresses = new ArrayList<ServerAddress>();
ServerAddress address = new ServerAddress(host, port);
serverAddresses.add(address);
List<MongoCredential> credentials = new ArrayList<MongoCredential>();
MongoCredential credential = MongoCredential.createGSSAPICredential(userName);
credential.withMechanismProperty("SERVICE_NAME", gssapiServiceName);
credential.withMechanismProperty("CANONICALIZE_HOST_NAME", true);
credentials.add(credential);
return new MongoClient(serverAddresses, credentials);
但是当我尝试执行下面的代码时,我会遇到异常
DB db = mongoTemplate.getDb();
Set<String> dbCollections1 = db.getCollectionNames();
例外:
