Spring Boot：嵌入 HTTP/2 和 TLS 的 Tomcat

Question

我尝试在 Windows 10 机器上使用 HTTP/2 和 TLS 配置 Tomcat Embedded 8.5.8。 tcnative-1.dll 和 openssl.exe 都包含在 PATH 环境变量中。 但是，我得到了以下堆栈跟踪。任何提示表示赞赏。

Answer 1

虽然这可能无法解决您的问题，但您使用的是哪个版本的Spring Boot？ 我在尝试将 Tomcat 从 8.5.6 提升到 8.5.8 时遇到了问题，就像一个端口已经在使用中一样。你能使用TomcatSpring Boot正在使用的默认版本吗？
