mongodb如何使用MongoOption从Java连接副本集

Question

目前我的代码是这样的

List<MongoCredential> creds = new ArrayList<MongoCredential>();
creds.add(MongoCredential.createCredential(username, dbName, password.toCharArray()));
MongoClientOptions.Builder optionsBuilder = MongoClientOptions.builder();
optionsBuilder.connectTimeout(Integer.parseInt(connectionTimeOut));
optionsBuilder.serverSelectionTimeout(Integer.parseInt(serverSelectionTimeOut));
optionsBuilder.socketTimeout(Integer.parseInt(socketTimeOut));
optionsBuilder.connectionsPerHost(Integer.parseInt(connections));
MongoClientOptions options = optionsBuilder.build();
mongoClient = new MongoClient(new ServerAddress(hostname, Integer.parseInt(port)), creds, options);

它正在连接到单个MongoDB，但我想连接MongoDB的副本集。您能帮我连接MongoDB的副本集吗
