当我们<http>在 xml 文件中使用该元素时，注册了一组默认过滤器。这提到了过滤器的顺序（无论我们选择应用哪个），在此之上，它提到：
<bean id="filterChainProxy" class="org.springframework.security.web.FilterChainProxy">
<constructor-arg>
<list>
<sec:filter-chain pattern="/restful/**" filters="
securityContextPersistenceFilterWithASCFalse,
basicAuthenticationFilter,
exceptionTranslationFilter,
filterSecurityInterceptor" />
<sec:filter-chain pattern="/**" filters="
securityContextPersistenceFilterWithASCTrue,
formLoginFilter,
exceptionTranslationFilter,
filterSecurityInterceptor" />
</list>
</constructor-arg>
</bean>
如果上面是默认过滤器列表，那么在调试过程中，我发现它RequestCacheAwareFilter也被调用了。这个过滤器是从哪里调用的，它在过滤器链中的位置是什么？在什么条件下AnonymousAuthenticationFilter配置到链中？
为我配置的默认过滤器链是什么？
编辑：我有 applicationContext.xml 和 springSecurity.xml。以下是我的 applicationContext.xml ：
