Question

环境：

spring-xxx-3.1.0-release for all spring related dependencies
Java 1.6
Tomcat 6

我已经实现了Spring安全性并使用了注释驱动的方法。似乎所有内容都配置正确，但是当执行SwitchUserFilter attemptSwitchUser方法时，userDetailsService始终为null。当我启动tomcat时，我可以使用调试器逐步执行此类，并且userDetailsService为非null。但是，当我手动调用attemptSwitchUser方法时，userDetailsService始终为null。这是我的xml配置：

的applicationContext-security.xml文件

我错误地遗漏了web.xml。事实上，SwitchUserFilter被调用了。

在没有失败的情况下，在SwitchUserFilter的第209行中，在将表单发布提交到j_spring_security_switch_user时，userDetailsService始终为null。在我看来，它不会在过滤器运行时被注入，但是在SwitchUserProcessingFilter中正确引用了我所见过的所有示例。我搜索过，无法找到任何线索。提前感谢任何想法或建议。

Spring Security过滤器不能直接在web.xml中使用。快速阅读描述安全过滤器链如何设置的参考文档的section 8.1 and 8.2。你需要在spring security配置中使用以下内容：

<!-- declare the filter bean -->
<beans:bean id="switchUserFilter" class="org.springframework.security.web.authentication.switchuser.SwitchUserFilter">
    <beans:property name="userDetailsService" ref="userDetailsService" />
    <beans:property name="switchUserUrl" value="/j_spring_security_switch_user" />
    <beans:property name="exitUserUrl" value="/j_spring_security_exit_user" />
    <beans:property name="targetUrl" value="/" />
</beans:bean>

<!-- include it in the security filter chain -->
<http auto-config="true" use-expressions="true">
    ...
    <custom-filter ref="switchUserFilter" position="SWITCH_USER_FILTER"/>
</http>
