基于Maven的spring_security入门
配置文件的修改点没什么变化，可以参考：http://blog.csdn.net/ouitiken/article/details/8830505

接下去就是spring-security的实现了
1. 修改web.xml
加入spring-security的过滤器，切忌必须加在struts2的过滤器前面。
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>SpringSecurityPrj</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:applicationContext*.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>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
接下来编写的是applicationContext-security.xml文件：
<?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-3.2.xsd">
<!-- 自动配置模式，拦截所有请求，有ROLE_USER才可以通过 -->
<http auto-config="true">
<intercept-url pattern="/**" access="ROLE_USER" />
</http>
<!-- 认证管理器。用户名密码都集成在配置文件中 -->
<authentication-manager>
<authentication-provider>
<user-service>
<user name="sharp" password="sharp" authorities="ROLE_USER" />
</user-service>
</authentication-provider>
</authentication-manager>
</beans:beans>
另外我新建了一个index.jsp文件，作用是登录成功后返回到index.jsp页面：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>登录首页</title>
</head>
<body>
<span color="red">登录成功!</span>
</body>
</html>
当我们在浏览器地址栏里输入下面的url：
http://localhost:8080/SpringSecurityPrj/
我们就可以再浏览器里看到用户登录界面：

呵呵，内置的登录页面，挺好玩的。没有使用过springsecurity可能还没发现我在那里配置用户名和密码吧，看下面一段代码，这里就是用户名和密码：
<user name="sharp" password="sharp" authorities="ROLE_USER"/> |
测试一：
我们录入用户名：admin；密码：admin，然后点击提交查询，最终页面如下：
