推荐答案

您通常使用自定义做<一个href=\"http://www.$c$crcorp.com/blog/spring/security-spring/writing-custom-userdetailsservice-for-spring-security.html\"相对=nofollow> 的UserDetailsS​​ervice 。在的UserDetailsS​​ervice 是一个DAO使用时，他们试图登录加载有关的用户数据。看一看在 loadUserByUsername（字符串的用户名）方法和春季的UserDetails 类。

You usually do it with a custom UserDetailsService. The UserDetailsService is a DAO used to load data about a user when they attempt login. Have a look at the loadUserByUsername(String username) method and the UserDetails class in spring.

哟需要在你的上下文中定义它：

Yo need to define it in your context:

<bean id="myDetailsService"
    class="com.company.service.impl.MyDetailsService" />

要使用它，你可以将它添加到您的安全配置：

To use it you can add this to your security config:

<authentication-manager>
    <authentication-provider user-service-ref="myDetailsService" />
</authentication-manager>

和你的安全过滤器将使用它。

and all you security filters will use it.

您可以问一个更具体的问题，如果你需要帮助实现它，但你不会有麻烦IMO。

You can ask a more specific question if you need help implementing it, but you won't have trouble IMO.
