base64编码与解码

Java 8的java.util套件中，新增了Base64的类别，可以用来处理Base64的编码与解码，用法如下 

  final Base64.Decoder decoder = Base64.getDecoder();

final Base64.Encoder encoder = Base64.getEncoder();

 

try {

 

final String text = "字串文字";

byte[] textByte;

textByte = text.getBytes("UTF-8");

//编码

final String encodedText = encoder.encodeToString(textByte);

System.out.println(encodedText);

//解码

System.out.println(new String(decoder.decode(encodedText), "UTF-8"));

} catch (UnsupportedEncodingException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}
