运行播放 v2 应用程序时出现异常

Question

我正在尝试启动 play v2 应用程序（之前由其他开发人员设置），但是当我运行激活器运行（应用程序本身位于 Java):

ProvisionException: Unable to provision, see the following errors:

1) Error in custom provider, akka.ConfigurationException: Type [akka.dispatch.BoundedControlAwareMessageQueueSemantics] specified as akka.actor.mailbox.requirement [akka.actor.mailbox.bounded-control-aware-queue-based] in config can't be loaded due to [akka.dispatch.BoundedControlAwareMessageQueueSemantics]

关于我可能配置错误的任何想法？我也可以复制 application.conf 文件。

Answer 1

此问题是由于为生成 API 文档而配置错误的 swagger 设置引起的。一旦我按照所有步骤设置 swagger 和 swagger-ui，问题就解决了。堆栈跟踪本身对解决问题没有用。
