akka cassandra持久性与java示例
使用Java我正在尝试使用Java测试akka cassandra持久性。在URL（）中，我试图使PersistentActor示例与cassandra一起工作，我遇到了以下问题 我正在使用下面提到的application.conf。你们有什么java实现示例可以让我开始使用吗？同样的代码在leveldb中运行良好。目前我们使用的是datastax 4.8。我希望这是application.conf的问题akka cassandra持久性与java示例,java,cassandra,persistence,akka,Java,Cassandra,Persistence,Akka,使用Java我正在尝试使用Java测试akka cassandra持久性。在URL（）中，我试图使PersistentActor示例与cassandra一起工作，我遇到了以下问题 我正在使用下面提到的application.conf。你们有什么java实现示例可以让我开始使用吗？同样的代码在leveldb中运行良好。目前我们使用的是datastax 4.8。我希望这是application.conf的问题 在我的项目中，我使用以下maven依赖项： <dependency
