case class Location(value: String)
这是我希望Scala中的案例类同时存在于Request和Response对象中。 对于Request对象(也是一个案例类),我有:
implicit val loc = new FromInput[Location] {
val marshaller = CoercedScalaResultMarshaller.default
def fromResult(node: marshaller.Node) = {
val ad = node.asInstanceOf[Map[String, Any]]
Location(
value = ad("value").asInstanceOf[String]
)
}
}
实际的Request对象本身正在反序列化,例如:
implicit val manual = new FromInput[Request] {
val marshaller = CoercedScalaResultMarshaller.default
def fromResult(node: marshaller.Node) = {
val ad = node.asInstanceOf[Map[String, Any]]
Request(
location = ad("location").asInstanceOf[Location],
startTimeEpochMs = ad("startTimeEpochMs").asInstanceOf[Long],
endTimeEpochMs = ad("endTimeEpochMs").asInstanceOf[Long]
)
}
}
implicit val LocationType = deriveObjectType[Unit, Location]()
implicit val InputLocationType = deriveInputObjectType[Location]()
implicit val RequestType = deriveInputObjectType[Request]()
代码可以编译,但是我有Runtime Exception: 无法初始化Schema.scala类并抛出NoClassDefinitionFound异常。
我是桑格利亚汽酒和graphQL的新手。如果您能在这里让我知道我的错误以及如何解决。这将是一个很大的帮助!非常感谢您的投入。
