SpringSecurity 3.2入门（2）环境搭建

　　由于目前Spring官方只提供Meven的下载方式，为了能以最快的速度入门使用框架，这里提供百度网盘下载链接。

　　注：本入门教程默认已经配置成功SpringMVC框架。

1、web.xml配置

<!-- 加载Spring的配置文件 -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:applicationContext.xml,
        classpath:spring-security.xml
    </param-value>
</context-param>

<!-- SpringSecurity 核心过滤器配置 -->
<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>

2、spring-security.xml命名空间配置

　　官方提供了两种配置方案

　　第一种、命名空间用beans开头，但是在配置中一直需要用<security:*>来配置，本教程将采用这种配置。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:security="http://www.springframework.org/schema/security"
    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-3.1.xsd">
    ...
</beans>

　　第二种、命名空间用security开头，在配置中不需要security前缀，但是bean的配置需要用<beans:bean>配置。

<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.xsd">
    ...
</beans:beans>

3、spring-security.xml详细配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:security="http://www.springframework.org/schema/security"
    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-3.1.xsd">

    <!-- 不过滤登录页面 -->
    <security:http pattern="/login.htm" security="none" />
    <security:http pattern="/login.jsp" security="none" />

    <!-- 配置SpringSecurity的http安全服务 -->
    <security:http auto-config="true">
        <!-- 只有ROLE_ADMIN权限用户才能访问/admin/**页面 -->
        <security:intercept-url pattern="/admin/**"
            access="ROLE_ADMIN" />

        <!-- 只有ROLE_ADMIN或ROLE_USER权限用户才能访问所有页面 -->
        <security:intercept-url pattern="/**"
            access="ROLE_ADMIN,ROLE_USER" />

    </security:http>

    <!-- 认证管理器，配置SpringSecutiry的权限信息 -->
    <security:authentication-manager>
        <security:authentication-provider>
            <!-- 帐户信息，指定用户名、密码和权限 -->
            <security:user-service>
                <security:user name="admin" password="admin"
                    authorities="ROLE_ADMIN,ROLE_USER" />
            </security:user-service>

        </security:authentication-provider>
    </security:authentication-manager>

</beans>  

4、环境测试

　　发布项目，当出现如下界面，输入用户名admin和密码admin，若成功进入首页，则环境搭建成功。
