acegi认证启用rememberme认证的步骤

启用Remember-me认证服务需要做的事情：

1、  在security的配置文件中定义remembermeprocessingfilter

<bean id="rememberMeProcessingFilter"

class="org.acegisecurity.ui.rememberme.RemenberMeProcessingFilte>

    <property name="authenticationManager">

        <ref local="authenticationManager" />

    </property>

    <property name="rememberMeServices">

        <ref local="rememberMeServices" />

    </property>

</bean>

<bean id="rememberMeServices"

  class="org.acegisecurity.ui.rememberme.TokenBasedRememberMeServices">

       <property name="userDetailsService" ref="jdbcDaoImpl" />

       <property name="key" value="springrocks" />

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

</bean>

2、  将上述过滤器定义的名字添加到过滤器链中，即filterChainproxy

3、  定义RememberMeauthenticationProvider认证提供者，并将他添加到认证管理器中

<bean id="rememberMeAuthenticationProvider"   class="org.acegisecurity.providers.RememberMeAuthenticationProvider">

    <property name="key" value="spring vock" />

</bean>

<bean id="authenticationManager"

       class="org.acegisecurity.providers.ProviderManager">

       <property name="providers">

           <list>

              <ref local="daoAuthenticationProvider" />

              <ref local="rememberMeAuthenticationProvider" />

           </list>

       </property>

</bean>

4、  将上述rememberservices注入到basicprocessingfilter

<bean id="basicProcessingFilter"

    class="org.acegisecurity.ui.basicauth.BasicProcessingFilter">

    <property name="authenticationManager"

        ref="authenticationManager" />

    <property name="authenticationEntryPoint"

        ref="basicProcessingFilterEntryPoint" />

    <property name="rememberMeServices" ref="rememberMeServices" />

    </bean>

通过以上四个步骤，我们就可以成功使用rememberme认证服务了。
