AbstractMethodError使用spray和akka

我想用喷雾和akka制作一些web服务 . GET请求工作正常(获取元素列表,值...使用spray-json)但是我的身份验证请求,我得到了一个预测,我不知道为什么 . 我做了一些单元测试,看看序列化/反序列化是否适用于marshallers,我看到一个格式良好的json对象 .

这是我的堆栈跟踪:

我找到了关于这个错误的主题,问题是scala / spray / akka版本,但是我检查了并且使用了正确的版本(scala 2.10.4 / spray 1.3.2 / akka 2.3.6)

任何人都有解决方案或轨道?

编辑:GET webservices也不起作用......我认为这是一个配置问题 .
