【总结】使用Scala实现Json与Case Class相互转换

import?org.json4s.native.Serialization.{read,?write}
object?Json2CaseClass?extends?App?{
??implicit?val?formats?=?org.json4s.DefaultFormats
??case?class?Class(_name:String,?students:?List[Student])
??case?class?Student(sid:String,?_name:String)
??val?s?=?"{"_name":"Class1","students":[{"sid":"1","_name":"小明"},{"sid":"1","_name":"小王"}]}"
??val?clazz:Class?=?read[Class](s)
??println(clazz)
??println(write(clazz))
}
