Question

我正在使用Spring Boot来连接到MongoDB，但它在尝试连接时给了我一个例外，奇怪的是这对我来说很有用，突然它开始给我这个错误。任何人都可以帮助我，如果这是问题，因为在这个端口上运行了一些其他服务（27017），如果是这样，我怎么能找到它。

我通过在VM上安装mongo然后运行Spring启动实例来解决了这个问题。

对我来说，嵌入式mongo驱动程序（de.flapdoodle.embed.mongo）无法正常工作，因此我删除了依赖项。

安装Mongo并运行它

sudo apt-key adv --keyserver hkp：//keyserver.ubuntu.com：80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
echo“ deb [arch = amd64，arm64] https://repo.mongodb.org/apt/ubuntu xenial / mongodb-org / 4.0 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list
sudo apt-get更新
sudo apt-get install -y mongodb-org
sudo服务mongod重新启动

运行Spring Boot应用程序
