将base64String转换为base64Binary Java

Question

I need to send base64Binary into SOAP service. I have this method in class, which create base64String:

public String encode(final String text) {
    byte[] msgBytes = text.getBytes(StandardCharsets.UTF-8);
    String base64String = DatatypeConverter.printBase64Binary(messageBytes);
    return base64String;
}

How can I convert base64String into base64Binary with bytes into base64String?

Answer 1

DatatypeConverter.parseBase64Binary can be used to decode a Base64 encoded String :

byte[] msgBytes = DatatypeConverter.parseBase64Binary(base64String);

If you want to convert the byte[] to a String , you can proceed like:

String text = new String(msgBytes , "UTF-8");
