Java Spring被动MongoDB连接到MongoDB云

我从下载了这个例子

我不明白如何让它工作

我在中设置了一个群集，他们为我提供：

如果我使用的是driver 3.6或更高版本：

mongodb+srv://stavalfi:<PASSWORD>@cluster0-9yjy8.mongodb.net/test

如何修复此问题？

我认为它没有SSL证书，或者可能是错误的或虚拟的SSL证书。这就是为什么在java.nio.channels.AsynchronousSocketChannel中不显示SSL支持的原因，文档中有：

如果您使用的是被动驱动程序，则SSL需要Netty。如果Netty可用且要使用的工厂尚未自定义，则自动配置会自动配置此工厂

---

确保在类路径上有netty，或者是选定的模块，或者是netty all。

对此进行了一些处理。您可以从中找到详细信息

首先，我尝试使用DSL方法，将所有设置都作为代码使用会很好：

application.yml

但是，这会崩溃，因为Netty通过Java堆栈触发DNS查找，但失败：

你知道如何使它工作吗？或者它不在我的手中？还有，哪里有错误的或虚假的SSL证书？你能重试吗 第二，使用驱动程序3.4或earlierFor SSL支持使用com.mongodb.connection.netty.NettyStreamFactoryFactory…我找不到任何关于如何使用的完整示例。您能提供一个在spring-boot-2中使用它的简单示例吗？
