我正在尝试运行一个spring启动应用程序，它试图连接到 MongoDB 启用ssl身份验证并在启动时接收错误：

Caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed:

阅读https://betterjavacode.medium.com/how-to-resolve-pkix-path-building-failed-in-docker-container-72cbb1698577 它说
复制cacerts之前，请确保导入目标服务的ssl证书。您可以使用keytool命令导入此证书。“
解决问题并允许访问 MongoDB 我需要下载mongodb所在的测试服务器的ssl证书并将其导入本地jdk吗？
