目前Spring官方只提供Meven的下载方式。但在http://maven.springframework.org中有SpringSecurity及其他所有Spring产品的下载方式。

http://maven.springframework.org/release/org/springframework/中有Spring相关的所有下载，但好像直到3.2版的，最新的版本在这个里面找不到

http://maven.springframework.org/release/org/springframework/security/spring-security/3.2.0.RELEASE/这个是SpringSecurity3.2的下载地址

Meven下载地址：

[html] view plain copy







<dependencies>

<dependency>

<groupId>org.springframework.security</groupId>

<artifactId>spring-security-web</artifactId>

<version>3.2.0.RELEASE</version>

</dependency>

<dependency>

<groupId>org.springframework.security</groupId>

<artifactId>spring-security-config</artifactId>

<version>3.2.0.RELEASE</version>

</dependency>

</dependencies>

本教程是基于SpringMVC3.2+Hibernate4+JPA2.0+SpringSecurity3.2的环境。SpringMVC3.2+Hibernate4+JPA2.0环境的搭建在这里就不多说了，主要讲下SpringSecurity的环境搭建

web.xml配置

[html] view plain copy







<!-- 加载Spring的配置文件 -->

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>

classpath:applicationContext.xml,

classpath:applicationContext-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>

applicationContext-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。

[html] view plain copy







<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.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。

[html] view plain copy







<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>

到此为止SpringSecurity的环境配置已基本完成

命名空间的配置可在spring的官方文档，第4章 Security Namespace Configuration 中找到，一下附上链接地址
