Json 使用Jerkson反序列化案例类（嵌套）

在EclipseScalaIDE中使用工作表包含代码和输出

这段简单的代码给出了ClassNotFoundException。由于某种原因，它似乎找不到Address类

类似：但它们的问题与Play框架和解析错误有关

import com.codahale.jerkson.Json._

object person {

  case class Address(city: String, state: String)
  case class Person(name: String, age: Int, addresses: Seq[Address])

  parse[Person]("""{"name":"James", "age":25, "addresses": [{"city":"New York", "state": "NY"}, {"city":"Brooklyn", "state": "NY"}]}""")
  //> java.lang.ClassNotFoundException: <empty>.person.Address

我通过使用lift json jar来实现它。请参阅文档中的

package com.example.json

import net.liftweb.json._

object HelloJson extends App {

  case class Address(city: String, state: String)
  case class Person(name: String, addresses: List[Address])

  implicit val formats = DefaultFormats
  val json = parse(""" { "name" : "Billy", "addresses" : [{"city": "New York", "state": "NY"}, {"city": "Washington", "state": "DC"}] } """)
  println(json.extract[Person])
}

实际上现在也有同样的问题，但我不想切换到lift json。
