【解决方案】报错：cannot find symbol [ERROR] symbol: class BASE64Decoder

执行mvn clean install -DskipTests对项目进行编译时，报错如下：

[ERROR] /Users/miaoying/Documents/.../utils/ThreeDESUtil.java:[4,16] cannot find symbol
[ERROR]   symbol:   class BASE64Decoder
[ERROR]   location: package sun.misc
[ERROR] /Users/miaoying/Documents/.../utils/ThreeDESUtil.java:[5,16] cannot find symbol
[ERROR]   symbol:   class BASE64Encoder
[ERROR]   location: package sun.misc

解决方案：

去掉 BASE64Encoder, BASE64Decoder 相关 import，改为如下：

BASE64Encoder base64en = new BASE64Encoder();
requestValue = base64en.encode(src);
// 改为
Base64.Encoder encoder = Base64.getMimeEncoder();
requestValue = encoder.encodeToString(src);

Base64.Decoder decoder = Base64.getMimeDecoder();
byte[] base64DValue = decoder.decode(URLValue);
