Java 中的播放框架 - "hello world" 示例中的错误
Play framework in Java - errors in "hello world" example
我正在尝试开始使用 play framework。
我尝试将“hello world”example 用于 Java，但在 运行 执行“sbt 运行”命令后我收到错误。
我在 CMD 中得到了很多行，最后几行是：
[info] p.c.s.AkkaHttpServer - Listening for HTTP on /[0:0:0:0:0:0:0:0]:9000
(Server started, use Enter to stop and go back to the console...)
当我尝试访问 http://localhost:9000/ 时，我遇到了很多新错误：

我没有对原来的 hello world 示例做任何更改，我使用的是 Java 17 和 sbt 1.6.1。
在此先感谢您的帮助！
Play 2.8支持Java8-11，我把我的环境变量“JAVA_HOME”设置为Java8JDK和命令sbt run成功了。
我正在尝试开始使用 play framework。 我尝试将“hello world”example 用于 Java，但在 运行 执行“sbt 运行”命令后我收到错误。 我在 CMD 中得到了很多行，最后几行是：
[info] p.c.s.AkkaHttpServer - Listening for HTTP on /[0:0:0:0:0:0:0:0]:9000
(Server started, use Enter to stop and go back to the console...)
当我尝试访问 http://localhost:9000/ 时，我遇到了很多新错误：

我没有对原来的 hello world 示例做任何更改，我使用的是 Java 17 和 sbt 1.6.1。
在此先感谢您的帮助！
Play 2.8支持Java8-11，我把我的环境变量“JAVA_HOME”设置为Java8JDK和命令sbt run成功了。
