Question

我写了一个可以在许多计算机上使用的代码，但是在树莓派上却不起作用。请帮助我任何想法，为什么它不起作用。我无法在任何计算机上解析cluster0-ll2zi.mongodb.net。但是代码不能只在一个代码中起作用。

我制作了一个jar文件，然后尝试启动它。

MongoClient  mongoClient = MongoClients.create("mongodb+srv://" + user + ":" + password + "@cluster0-ll2zi.mongodb.net/test?retryWrites=true&w=majority");

错误
