【问题描述】：

我正在尝试使用 Spring 安全性执行一些自定义身份验证。

我已经阅读了一些关于它的内容：

https://***.com/a/4074532/759452 https://***.com/a/2701722/759452 http://static.springsource.org/spring-security/site/

我还发现了一个关于这个 的有趣对话：http://forum.springsource.org/showthread.php?53972-Problem-when-finding-springSecurityFilterChain-bean

所以，在我的 web.xml 中有

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <display-name>Secured Account</display-name>

  <servlet>
    <servlet-name>mysecuredapp</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>mysecuredapp</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>


  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/mysecuredapp-security.xml</param-value>
  </context-param>


  <filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>

在 mysecuredapp-servlet.xml 我有

<?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" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
        http://www.springframework.org/schema/security
        http://www.springframework.org/schema/security/spring-security-3.0.xsd" >

    <http auto-config="true">
        <intercept-url pattern="/account/*" access="ROLE_USER, ROLE_ADMIN, ROLE_MASTER" />
        <intercept-url pattern="/admin/*" access="ROLE_ADMIN, ROLE_MASTER" />
        <intercept-url pattern="/master/*" access="ROLE_MASTER" />
    </http>


    <authentication-manager>
        <authentication-provider ref="daoAuthenticationProvider" />
    </authentication-manager>

    <beans:bean id="daoAuthenticationProvider" class="org.springframework.security.authentication.dao.DaoAuthenticationProvider" >
        <beans:property name="userDetailsService" ref="userDetailsService" />
    </beans:bean>


</beans:beans>

这是我的 pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

当我启动 tomcat（在 Eclipse 中）时，我得到了这个 。知道为什么会出现这种情况吗？

提前致谢

【参考方案1】：

这是我自己犯的一个愚蠢的错误......因为我遇到问题的原因完全相同：不包括部署程序集的 Spring 依赖项。

有关详细信息，请参阅我之前发布的此答案：Maven + Spring + Dynamic Web Module ( Eclipse ) = java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

【讨论】：

你能相信我有同样的问题（和同样的修复）吗？我无法解释为什么会发生这种情况......

【参考方案2】：

过滤器链是否有可能没有选择您的用户详细信息服务 bean？您的 mysecuredapp-servlet.xml 文件中似乎没有组件扫描指令，并且委派过滤器的 contextConfigLocation 仅指向该文件。

我可能是错的，但我相当确定过滤器的 Spring 上下文与调度程序 servlet 的上下文是分开的。您需要在安全 XML 文件中包含组件扫描，或者将主 Spring beans 文件添加到 contextConfigLocation。

【讨论】：

我用 更新了 mysecuredapp-security.xml 但我仍然遇到同样的错误。
