Question

在我的应用程序中，我使用MongoDB，它在Wildfly 11.0.0.Alpha1本地工作正常 - 在本地应用程序服务器和本地MongoDB数据库上部署之后，应用程序可以在上下文路径和端口访问 - 一切都很好。

我的下一步是在服务器机器上将此应用程序部署到JBoss服务器。我将MongoDB URI更改为mongoDB服务器：

mongodb://user:password@server:27017/databaseName?authMechanism=SCRAM-SHA-1&ssl=true

如果我部署此应用程序，我会在底部获得以下日志条目。其实我不知道为什么以及它意味着什么。有没有人暗示在这种情况下我能做些什么来解决它？

Answer 1

这可能与mongodb连接上发生的超时有关。尝试在构建连接时使用API来增加超时

  MongoClientOptions.Builder builder = new MongoClientOptions.Builder();
builder.maxConnectionIdleTime(<long_time>);

或者尝试删除那些没有超时的文件

将Java-应用程序连接到MongoDB - com.mongodb.MongoSocketReadException：过早地到达流的末尾
