scala - Play Framework Scala Hello-World 在 Ubuntu 20 上失败

Question

基本的 Play 框架示例 (play-scala-hello-world-tutorial) 在使用 OpenAdopt JDK 的 Ubuntu 20 上失败，但在 Macos 上运行良好。我的 Linux 设置有什么问题吗？

(Server started, use Enter to stop and go back to the console...)

curl 本地主机:9000
结果如下:

我在使用 JDK-11 时遇到了同样的问题
尝试使用 Java8 解决了这个问题。
