播放Framework2.7.x编译时DI错误

Question

从https://github.com/playframework/play-socket.io/tree/master/samples/scala/chat创建项目并获得编译错误

overriding method applicationLifecycle in trait MyApplication of type => play.api.inject.DefaultApplicationLifecycle;
 lazy value applicationLifecycle in class BuiltInComponentsFromContext of type play.api.inject.ApplicationLifecycle has incompatible type

试玩2.6.23和2.7.2

Answer 1

从线路中删除以下MyApplication应该可以使其工作：

override def applicationLifecycle: DefaultApplicationLifecycle

用

1. git clone https://github.com/playframework/play-socket.io.git
2. cd play-socket
3. 从play-socket.io/samples/scala/chat/app/modules/MyApplicationLoader.scala中删除覆盖
4. 来自根项目dir play-socket/的sbt "scalaChat/run"
5. 命中http://localhost:9000/
