Base64与String解码编码

String test = "test字符串";

//方法一
final Base64.Encoder encoder = Base64.getEncoder();
final Base64.Decoder decoder = Base64.getDecoder();
String encodeText = encoder.encodeToString(test.getBytes("UTF-8"));
System.out.println(encodeText);
String s = new String(decoder.decode(encodeText), "UTF-8");
System.out.println(s)

//方法二
encodeText = Base64Utils.encodeToString(s.getBytes("UTF-8"));
System.out.println("2:"+encodeText);
String s1 = new String(Base64Utils.decode(encodeText.getBytes()),"UTF-8");
System.out.println("s1:"+s1);
