scala - Play Framework : EhCache issue on every code hot compile

Question

在 Play 2.5.3 中，使用 Scala:

我使用缓存作为模块，每次更改代码然后刷新浏览器时，重新编译后都会遇到以下问题:

[TechnicalException: com.google.inject.ProvisionException: Unable to provision, see the following errors:

1) Error in custom provider, play.api.cache.EhCacheExistsException: An EhCache instance with name 'play' already exists.

This usually indicates that multiple instances of a dependent component (e.g. a Play application) have been started at the same time.

我正在为一些 Actor 使用缓存(一个命名的缓存，而不是默认的 Play )。我该如何解决这个问题？

谢谢!

您是否禁用了 EHCache？

在application.conf中:-

# disable default Play framework cache plugin
play.modules.disabled += "play.api.cache.EhCacheModule"
