服务器启动时Spring Security Config错误

Question

如果我在security.xml文件中保留remember-me元素并启动服务器,则会出现以下错误.

没有UserDetailsS​​ervice注册.......

如果我删除这个记住我的元素,那么它工作正常.

如何摆脱这个错误......

Spring Security提供的RememberMeServices 需要UserDetailsS​​ervice才能工作.这意味着您有两种选择:

1)如果可能,我建议将此作为您的最佳选择.而不是编写自定义AuthenticationProvider,编写自定义UserDetailsS​​ervice.您可以找到一个查看InMemoryDaoImpl的示例UserDetailsS​​ervice 然后您可以将其连线,类似于下面的配置.请注意,您也将删除自定义AuthenticationManager.

<http ..>
  ...
  <remember-me key="abcdefgh" />
</http>
<authentication-manager>
  <authentication-provider user-service-ref="myUserService"/>
</authentication-manager>
<beans:bean id="myUserService" class="MyUserService"/>

2)编写自己的RememberMeServices实现,不需要UserDetailsS​​ervice.您可以查看TokenBasedRememberMeServices作为示例(但它需要UserDetailsS​​ervice).如果要使用命名空间配置,则RememberMeServices实现需要实现LogoutHandler.然后,您可以使用命名空间来连接它.

<http ..>
  ...
  <remember-me ref="myRememberMeServices"/>
</http>
<beans:bean id="myRememberMeServices" class="sample.MyRememberMeServices"/>
