如何使用fasterxml.jackson验证scala中的嵌套案例类

Question

I'm new to scala and I encountered a problem to validate free style json vs my predefined case class, assume:

case class sth(f1: String,
               f2: Option[String],
               f3: Map[String, sth2],
               f4: Array[sth2],
        )

case class sth2(subF1: String, subF2: List[sth3])
case class sth3(subF:String)

I tried Java 8 jackson validator describe in here , but how do I define nested case class (within Map and Array) and throw custom exception message?

Many thanks in advance for any answer!

发现这个包，部分解决了我的问题，而是需要手动定义JSON模式为它工作
