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：

<dependencies><!-- Commons --><dependency><groupId>commons-dbcp</groupId><artifactId>commons-dbcp</artifactId><version>1.4</version></dependency><!-- Log --><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency><!-- Struts2 --><dependency><groupId>org.freemarker</groupId><artifactId>freemarker</artifactId><version>2.3.18</version></dependency><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-core</artifactId><version>2.3.16.3</version></dependency><dependency><groupId>org.apache.struts</groupId><artifactId>struts2-spring-plugin</artifactId><version>2.3.16.3</version></dependency><!-- Spring --><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>3.2.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>3.2.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>3.2.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>3.2.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>3.2.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-expression</artifactId><version>3.2.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-jdbc</artifactId><version>3.2.8.RELEASE</version></dependency><dependency><groupId>org.springframework.security</groupId><artifactId>spring-security-core</artifactId><version>3.2.4.RELEASE</version></dependency><dependency><groupId>org.springframework.security</groupId><artifactId>spring-security-web</artifactId><version>3.2.4.RELEASE</version></dependency><dependency><groupId>org.springframework.security</groupId><artifactId>spring-security-config</artifactId><version>3.2.4.RELEASE</version></dependency><!-- Mybatis --><dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId><version>3.0.6</version></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId><version>1.0.2</version></dependency><!-- Database --><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.31</version></dependency></dependencies>

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.xsdhttp://www.springframework.org/schema/securityhttp://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。
