Shiro报错-[org.apache.shiro.mgt.AbstractRememberMeManager] - There was a failure while trying to retrieve remembered principals.

2017-04-08 11:55:33,010 WARN [org.apache.shiro.mgt.AbstractRememberMeManager] - There was a failure while trying to retrieve remembered principals. This could be due to a configuration problem or corrupted principals. This could also be due to a recently changed encryption key, if you are using a shiro.ini file, this property would be 'securityManager.rememberMeManager.cipherKey' see: http://shiro.apache.org/web.html#Web-RememberMeServices. The remembered identity will be forgotten and not used for this request.

解决方法：

在自定义Realm中添加

<property name="storedCredentialsHexEncoded" value="true"/>

    <bean id="sHA1Realm" class="cn.lonecloud.realms.SHA1Realm">
         <!--配置加密算法-->
         <property name="credentialsMatcher">
             <!--shiro加密策略MD5-->
             <bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
                 <!--加密的策略-->
                 <property name="hashAlgorithmName" value="SHA1"/>
                 <!--加密的次数-->
                 <property name="hashIterations" value="10"/>
                 <property name="storedCredentialsHexEncoded" value="true"/>
             </bean>
         </property>
     </bean>
