我想在Spring Boot服务中添加一个应用程序，但是我希望它只能以root身份运行。当我尝试以其他用户身份运行它时，出现错误：
Failed to start component [Connector[HTTP/1.1-8081]]
org.apache.catalina.LifecycleException: Protocol handler start failed
https://pastecode.xyz/view/2410ddfc
当我使用sudo运行它时，它会正确启动。
该应用程序使用“让我们加密”证书，我不知道这是否重要。
我认为，没有运行Tomcat的权限。 :-(
我不知道该怎么办。
谢谢您的帮助。

随着堆栈跟踪的读取，您将无法访问该文件：

最底层的caused by语句始终是异常的根本原因。
如果您的服务器将以root以外的[user]身份运行，这绝对是个好主意，请使该文件可用于特定的[user]。
作为root用户的解决方法：
mkdir /home/[user]/key
cp -p /etc/letsencrypt/live/dawid.cloud/keystore.p12 /home/[user]/key/
chown -R [user].[user] /home/[user]/key
[user]是您的用户名。
我敢打赌，还有一种更灵活的解决方案可以使用certbot来自动完成
或您用来获取“让我们加密”证书的工具。
编辑：certbot deploy hook似乎是in an answer on superuser.com指出的一个很好的下一个搜索词
