我目前正在开发一个连接到远程MongoDB数据库的Java应用程序。
我已经按照MongoDB指南实现了身份验证方法:
MongoCredential credential = MongoCredential.createScramSha1Credential(username, credentialDatabase, password.toCharArray());
MongoClient client = new MongoClient(new ServerAddress(hostname, port), Arrays.asList(credential));
mongoDatabase = client.getDatabase(database);
应用程序能够正确连接到数据库,但有一件事我无法理解。它可以成功连接到远程服务器,但我不知道为什么它还试图连接到 localhost:27017。

com.mongodb.MongoSocketOpenException: Exception opening socket
所以,我怎样才能告诉它我不想连接到本地主机?谢谢。
