scala如何通过迭代或类似的方式通过修改case类的所有字符串值来复制新的case类？

Posted 2021-04-10

private val replacements = Map("&" -> "&amp;", """"""" -> "&quot;", "<" -> "&lt;", ">" -> "&gt;", "'" -> " &apos;")
def escape(str: String): String = {  
  str.map(c => replacements.getOrElse(c.toString, c)).mkString
}

case class Table(length: Int, prop: String)
case class User (name: String, age: Int, posts: List[String], ex: List[Table])
val user = User("""this & that gonna be < or > so ' all " has to be changed""", 25, List("Lorem$", "Ipsum$"), List(Table(12, "smthin'g")))

想要将具有转义功能的User的新实例复制到所有字符串值，这些功能需要应用到不同的案例类中，案例类可以具有10-20个字符串值

这样的事情？
