scala - Swagger-play 在应用程序初始化期间抛出异常

Question

我在尝试将 Swagger 附加到 Play Framework 应用程序时遇到问题。 Swagger lib 扫描未初始化的类并导致问题。有什么处理建议吗？

我提取了部分应用程序作为示例:

CreationException: Unable to create injector, see the following errors:

问题已在最新的、未记录的 swagger 版本中修复。只需使用:

libraryDependencies ++= Seq(
  "io.swagger" %% "swagger-play2" % "1.5.3"
)
