问题描述
我正在学习spring security，看了网上的文档后（下面的附件），动手试了下，结果报错了，不知道是什么回事？我用的是MyEclipse第一步我先创建个web project,然后把spring-security-samples-contacts-3.0.2.RELEASE.rar里lib里的jar拷入到项目里的lib里。然后在web.xml加入了这些代码<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>再然后在applicationcontext.xml加入了这些代码.<?xml version="1.0" encoding="UTF-8"?><b:beans xmlns="http://www.springframework.org/schema/security" xmlns:b="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

<authentication-provider> <user-service> <user name="user" password="user" authorities="ROLE_USER"/> </user-service> </authentication-provider> </authentication-manager> </b:beans>然后配置tomcat服务器，运行就报这样的错.严重: Context initialization failedorg.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [bigbank.BankDaoStub] for bean with name 'bankDao'

解决方案
你的web.xml是照他的文章上写的？不要有<description>和<context-param>之类的标签哦
解决方案二：
http://static.springsource.org/spring-security/site/tutorial.html还是看官方的吧。
解决方案三：
http://liukai.iteye.com/admin/blogs/982088看下这个吧照着弄,基本上也能跑个最简单的springsecurity
解决方案四：
还要看看你的代码中有没有给ROLE_USER指定权限.
解决方案五：
首先你自己的类就没配置到spring上，bigbank.BankDaoStub这个，spring没找到。其次spring security要在web.xml里配置 <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter>还有，spring security的jar包不止一个，至少需要引入(以3.0.5版为例)：spring-security-core-3.0.5.RELEASE.jarspring-security-config-3.0.5.RELEASE.jarspring-security-taglibs-3.0.5.RELEASE.jarspring-security-web-3.0.5.RELEASE.jar这四个
解决方案六：
java.lang.ClassNotFoundException: bigbank.BankDaoStub很明显，这个类没找到，你是否把这个类文件放到了classpath目录下面？
