Unable to execute 'doFinal' with cipher instance [javax.crypto.Cipher@3d52dc...

报错内容：org.apache.shiro.crypto.CryptoException: Unable to execute 'doFinal' with cipher instance [javax.crypto.Cipher@58c5686a].

前提： http://localhost:8080/emp/list 需要认证；

复现方法：当http://localhost:8080/emp/list没有认证的时候，访问该地址，跳转到登入页面，且报错：

org.apache.shiro.crypto.CryptoException: Unable to execute 'doFinal' with cipher instance [javax.crypto.Cipher@58c5686a].；

解决办法：在realm配置中加入

 1 <bean id="jdbcRealm" class="ssm.shiro.ShiroRealm">
 2         <property name="credentialsMatcher">
 3             <bean
 4                 class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
 5                 
 6                 <property name="hashAlgorithmName" value="MD5">property>
 7
