java开发：JDK1.8新特性：base64加密

在Java 8中，Base64编码已经成为Java类库的标准。使用方法如下：

 		 String text = "base64 in java8 lib";
        String base64 = null;
        try {
            base64 = Base64.getEncoder().encodeToString(text.getBytes("UTF-8"));
            System.out.println("加密："+base64);
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }

        try {
            byte[] bytes = Base64.getDecoder().decode(base64);
            System.out.println("解密：" + new String(bytes, "UTF-8"));
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }

输出结果：
