请问我下载了乌云的 digatalAllData，说明上写着用 case class 解析出数据，那有没有详细的方法？

如题，下载了 2.9g 的数据不熟悉 scala 不知道怎么读取出来 readme 如下

“如果使用 scala,可以使用如下 case class 解析出数据

case class Answer(answer_id: Long,
				  question_id: Long,
				  question_title: String, 
				  question_topics: Array[Long], 
				  votup_count: Long)

case class Article(id: Long, title: String, votup_count: Long)
case class Question(question_followers: Long, 
					question_id: Long, 
					question_title: String, 
					question_topics: Array[Long])

case class userStringId(CREATED_ANSWERS: Array[Answer],
                          CREATED_ARTICLES: Array[Article],
                          CREATED_QUESTIONS: Array[Question],
                          FOLLOWED_QUESTIONS: Array[Question],
                          VOTEUPED_ANSWERS: Array[Answer],
                          VOTEUPED_ARTICLES: Array[Article],
                          followers_count: Long,
                          id: String)

case class userDigitalId(CREATED_ANSWERS: Array[Answer],
                           CREATED_ARTICLES: Array[Article],
                           CREATED_QUESTIONS: Array[Question],
