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：
