Answer 1

参考一下：

shiro报错.crypto.CryptoException: Unable to correctly extract the Initialization Vector or ciphertext. - 走看看 这个错误困扰了我很久 org.apache.shiro.crypto.CryptoException: Unable to correctly extract the Initialization V http://t.zoukankan.com/StarChen20-p-14054692.html

最后的报错中提示有空指针异常，从代码层面检查一下看看
