3. 加密
// 默认加密/解密算法是 PBEWithMD5AndDES
StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
encryptor.setPassword(KEY);
return encryptor.encrypt(text);
# 注意:这里每次加密得到的密文都是不一样的;
4. 解密
StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
encryptor.setPassword(KEY);
return encryptor.decrypt(ciphertext);
