如何将案例类转换为字符串

Question

如果我有一个如下的案例类：

case class Student(name: String, activities: Seq[String], grade: String)

我有一个这样的列表：

val students = List(
      Student("John",List("soccer","Video Games"),"9th"),
      Student("Jane",List("sword fighting","debate"),"10th")
     )

如何将整个内容转换为如下所示的字符串：

johnsoccervideogames9thjaneswordfightingdebate10th

我想把这个字符串作为MD5的一部分。

Answer 1

这似乎可以满足您的期望。

students.map( student => student.name + student.activities.mkString + student.grade).mkString.toLowerCase.replaceAll("\\s", "")
