spring security 无法获取当前用户

这是我的配置文件内容：

<?xml version="1.0" encoding="UTF-8"?>

<beans:beans xmlns="http://www.springframework.org/schema/security"

	xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

		<remember-me key="RememberUserInfo" />



		<custom-filter ref="securityInterceptorFilter" after="FILTER_SECURITY_INTERCEPTOR" />

	</http>

	<authentication-manager alias="authenticationManager">

		<authentication-provider user-service-ref="userDetailServiceImpl">

			<!--<password-encoder hash="sha-256" base64="true" />-->



		</authentication-provider>

	</authentication-manager>

	<!-- 实现了UserDetailsService的Bean -->

	<beans:bean id="userDetailServiceImpl"

		class="com.dxb.core.security2.UserDetailServiceImpl">

		<beans:property name="usersService" ref="usersService"></beans:property>

	</beans:bean>

	<!-- 自定义验证过滤器 -->

	<beans:bean id="securityInterceptorFilter"

		class="com.dxb.core.security2.SecurityInterceptorFilter">

		<beans:property name="securityDataSource"  ref="securityDataSource" />

	</beans:bean>

	<!-- 验证数据源加载 -->

	<beans:bean id="securityDataSource"

		class="com.dxb.core.security2.SecurityMetadataSource">

		<beans:property name="rolesService" ref="rolesService" />

	</beans:bean>





</beans:beans>

在登录action中执行了以下代码：

Authentication authRequest = new UsernamePasswordAuthenticationToken(

				user.getAccount(), user.getPassword());



		Authentication authentication = authenticationManager

				.authenticate(authRequest);

		

		SecurityContextHolder.getContext().setAuthentication(authentication);

登录成功后，在securityInterceptorFilter过滤器中无法获取当前用户。
请问怎么把用户信息放入容器啊？？？？？ --------------------编程问答-------------------- 不知道是不是配置的问题 --------------------编程问答-------------------- <http pattern="/index.jsp" security="none" />
<http pattern="/system/login_Users.do" security="none" />
去掉就行了，不知道为什么
