部署时的MongoDB问题

Question

I am fairly new to MongoDB: my app running on my mac does not deploy well on ubuntu.

I have a very basic program that takes a JSon file and dumps it in a MongoDB db. The MongoDB db is on a remote Ubuntu server called db .

The program works fine on my Mac, in Eclipse and command line.

When I deploy it on my Ubuntu-based app server (different than the db server), I get:

[cluster-ClusterId{value='572387cf96720e25144dce5b', description='null'}-db:27017] INFO org.mongodb.driver.cluster - Exception in monitor thread while connecting to server db:27017
com.mongodb.MongoInterruptedException: Interrupted acquiring a permit to retrieve an item from the pool

The app server can ping the db server.

Answer 1

我认为这是因为我的应用正在尝试将null对象另存为文档...
