java - 无法弄清楚为什么我不断收到 com.mongodb.MongoSocketReadException : Prematurely reached end of stream

Question

试图弄清楚为什么我总是在下面显示异常。

这是我的代码:

CodecRegistry pojoCodecRegistry = fromRegistries(MongoClient.getDefaultCodecRegistry(), fromProviders(PojoCodecProvider.builder().automatic(true).build()));
MongoClientOptions.Builder options_builder = new MongoClientOptions.Builder();
options_builder.maxConnectionIdleTime(60000);
MongoClientURI uri = new MongoClientURI("mongodb+srv://USERNAME:MYPASSWORD@database-yyc55.mongodb.net/test\n", options_builder);
MongoClient mongoClient = new MongoClient(uri);
MongoDatabase database = mongoClient.getDatabase("test");
database = database.withCodecRegistry(pojoCodecRegistry);
MongoCollection<AppUser> collection = database.getCollection("users", AppUser.class);
AppUser appUser = null;
String userName = null;
appUser = collection.find().first();
userName = facebook.getName();

如您所见，我做了一些研究并尝试将 maxIdleConnection 设置为 60000 毫秒，但我仍然不断收到此异常。奇怪的是 - 这段代码之前有效，在一天不使用数据库后，它开始发生。

异常(exception):

com.mongodb.MongoSocketReadException: Prematurely reached end of stream at com.mongodb.connection.SocketStream.read(SocketStream.java:87) at com.mongodb.connection.InternalStreamConnection.receiveResponseBuffers(InternalStreamConnection.java:547) at com.mongodb.connection.InternalStreamConnection.receiveMessage(InternalStreamConnection.java:418) at com.mongodb.connection.InternalStreamConnection.receiveCommandMessageResponse(InternalStreamConnection.java:290) at com.mongodb.connection.InternalStreamConnection.sendAndReceive(InternalStreamConnection.java:255) at com.mongodb.connection.CommandHelper.sendAndReceive(CommandHelper.java:84) at com.mongodb.connection.CommandHelper.executeCommand(CommandHelper.java:34) at com.mongodb.connection.InternalStreamConnectionInitializer.initializeConnectionDescription(InternalStreamConnectionInitializer.java:91) at com.mongodb.connection.InternalStreamConnectionInitializer.initialize(InternalStreamConnectionInitializer.java:51) at com.mongodb.connection.InternalStreamConnection.open(InternalStreamConnection.java:127) at com.mongodb.connection.DefaultServerMonitor$ServerMonitorRunnable.run(DefaultServerMonitor.java:114) at java.lang.Thread.run(Thread.java:748)

感谢您的帮助。

显然，问题是我的 IP 已更改，并且在服务器上，我不允许访问任何其他 IP。它解决了它，但我无法解释为什么我得到:“com.mongodb.MongoSocketReadException:过早到达流的结尾”异常。我还在我的代码中添加了选项构建器，如您在上面的问题中所见。
