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
pom.xml的依赖参考：

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：
登录失败了哦！
测试二：我们录入用户名：sharp；密码：sharp；如下图：
点击提交查询后，页面如下：
页面跳转到index.jsp页面，登录成功了。
怀有希望!!
