推荐答案

此示例中列出的依赖项是play安装附带的依赖项.这些版本与您使用的Play框架版本匹配.

The dependencies listed in this example are the ones that are shipped with your installation of play. The versions match the Play framework version you are using.

Play框架是模块化的，因此您不必在应用程序中使用其所有模块.这就是为什么必须指定所需的模块的原因.

Play framework is modular so you don't have to use all of its modules in your application. That is why you must specify which modules you want.
