我正在尝试实现一个过滤器，最终将记录系统内的用户导航。

我的春季环境是这样的：

<?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"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:sec="http://www.springframework.org/schema/security"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.2.xsd
    http://www.springframework.org/schema/security
                        http://www.springframework.org/schema/security/spring-security-3.1.xsd">

<!-- <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" />

我的过滤器类是这样的：

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);
}

}

所以当我运行它时，我没有收到任何错误，我的过滤器甚至被触发了，但它从来没有调用我的 doFilterInternal 方法。这是日志的摘录：

那么为什么不调用我的 doFilterInternal 呢？提前致谢。

你为什么要延长RequestContextFilter？

RequestContextFilter是 的子类OncePerRequestFilter，其中包含防止每个请求多次调用过滤器类的逻辑。
