Play Framework 2.7.x 编译时 DI 错误

Question

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

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

试试 Play 2.6.23 和 2.7.2

Answer 1

从 MyApplication 中删除以下 line 应该可以正常工作：

override def applicationLifecycle: DefaultApplicationLifecycle

使用

进行测试

git clone https://github.com/playframework/play-socket.io.git
cd play-socket
移除 play-socket.io/samples/scala/chat/app/modules/MyApplicationLoader.scala
sbt "scalaChat/run" 来自根项目目录 play-socket/
命中http://localhost:9000/
