Base64 encoding in Java / Groovy

Question

What is the proper way to convert a byte [] to a Base64 string in Java? Better yet would be Grails / Groovy because it tells me that the encodeAsBase64() function is deprecated. The sun.misc.BASE64Encoder package isn't recommended for use and outputs a different size string on some Windows platforms.

Answer 1

The preferred way to do this in groovy is:

 def encoded = "Hello World".bytes.encodeBase64().toString()  assert encoded == "SGVsbG8gV29ybGQ="  def decoded = new String("SGVsbG8gV29ybGQ=".decodeBase64())  assert decoded == "Hello World"
