我正在尝试实现一个过滤器，最终将记录用户在系统内的导航。
我的Spring上下文如下：
<?xml version="1.0" encoding="UTF-8"?>
<b:beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:b="http://www.springframework.org/schema/beans"

<!-- <sec:global-method-security secured-annotations="enabled" /> -->
<!-- Importa configuracion de seguridad de ldap -->
<import resource="classpath:/spring/ldap-config.xml" />
<sec:http pattern="/resources" security="none" />
<sec:http use-expressions="true" auto-config="true">
<sec:intercept-url pattern="/seguridad/login.xhtml"
access="permitAll" />
<sec:intercept-url pattern="/*.jsp" access="isAuthenticated()" />
<sec:intercept-url pattern="/" access="isAuthenticated()" />
<sec:intercept-url pattern="/views/**" access="isAuthenticated()" />
<sec:form-login login-page="/seguridad/login.xhtml"
authentication-failure-url="/seguridad/login.xhtml" />
<sec:logout invalidate-session="true" />
<sec:access-denied-handler error-page="/seguridad/accesoDenegado.xhtml" />
<sec:custom-filter ref="navegationFilter" after="FILTER_SECURITY_INTERCEPTOR" />
</sec:http>
<sec:authentication-manager alias="authenticationManager">
<sec:authentication-provider
user-service-ref="userDetailService" />
</sec:authentication-manager>
<b:bean id="navegationFilter" class="com.praxis.desvucem.web.service.seguridad.NavegationFilter" />
我的过滤器类如下所示：
package com.praxis.desvucem.web.service.seguridad;
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
import org.springframework.web.filter.RequestContextFilter;
import javax.servlet.http.HttpSession;
public class NavegationFilter extends RequestContextFilter {
protected static Logger logger = Logger.getLogger("service");
@Override
// @LogMe
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException {
logger.debug("Running Navegation filter");
HttpSession session = request.getSession(false);
if (session != null) {
logger.debug("User is trying to access site for the second time");
logger.debug("Request URI: " + request.getRequestURI());
}
else {
logger.debug("Session is null");
}
logger.debug("Continue with remaining filters");
filterChain.doFilter(request, response);
}
当我运行它时，没有任何错误，并且我的过滤器甚至被触发，但它从未调用我的doFilterInternal方法。以下是日志的摘录：

那么为什么我的doFilterInternal方法没有被调用呢？谢谢提前。
