encodeToString不是Base64的成员？

Question

在scala中，我有部分代码在做Base64.encodeToString＆amp; Base64.decode

 def genKeyAES(): String = {
    val keyGen = KeyGenerator.getInstance("AES")
    keyGen.init(128)
    val key = keyGen.generateKey()
    val base64Str = Base64.encodeToString(key.getEncoded())
    base64Str
  }
  def loadKeyAES(base64Key: String): SecretKey = {
    val bytes = Base64.decode(base64Key)
    val key = new SecretKeySpec(bytes, "AES")
    return key
  }

错误说，

Type value encodeToString is not a member of object java.util.Base64
Type value decode is not a member of object java.util.Base64

我导入的包是java.util.Base64     我该如何解决这个问题？

Answer 1

替换

Base64.encodeToString(key.getEncoded())

通过

Base64.getEncoder.encodeToString(key.getEncoded())

和

Base64.decode(base64Key)

通过

Base64.getDecoder.decode(base64Key)
