java 8 Base64用法

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();
final String text = "字串文字";
final byte[] 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"));

final Base64.Decoder decoder = Base64.getDecoder();
final Base64.Encoder encoder = Base64.getEncoder();
final String text = "字串文字";
final byte[] 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"));
