1.配置rememberMeManager结点

rememberMeManager使用CookieRememberMeManager作为实现类

<bean id="rememberMeManager" class="org.apache.shiro.web.mgt.CookieRememberMeManager">
	   <property name="cookie" ref="simpleCookie"></property>
       <property name="cipherKey" value="#{T(org.apache.shiro.codec.Base64).decode('6ZmI6I2j5Y+R5aSn5ZOlAA==')}"/>
</bean>

2.配置simpleCookie

<bean id="simpleCookie" class="org.apache.shiro.web.servlet.SimpleCookie">
	   <property name="httpOnly" value="true"></property>
	   <!-- 存活时间 -->
	   <property name="maxAge" value="#{60*60*24*7}"></property>
	   <property name="name" value="rememberMe"></property>
</bean>

3.在securityManager中添加rememberMeManager

<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
	    <!-- Single realm app.  If you have multiple realms, use the 'realms' property instead. -->
	    <property name="realm" ref="myRealm"/>
	    <!-- By default the servlet container sessions will be used.  Uncomment this line
	         to use shiro's native sessions (see the JavaDoc for more): -->
	    <!-- <property name="sessionMode" value="native"/> -->
	    <property name="rememberMeManager" ref="rememberMeManager"></property>
</bean>

4.配置Realm允许存储（storedCredentialsHexEncoded）

<bean id="myRealm" class="top.weweb.hawk.shiro.MyRealm">
		<property name="credentialsMatcher">
	    		<bean class="org.apache.shiro.authc.credential.HashedCredentialsMatcher">
	    			<property name="hashAlgorithmName" value="MD5"></property>
	    			<property name="storedCredentialsHexEncoded" value="true"></property>
	    		</bean>
    	</property>
</bean>
