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：

 

<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

 

<!-- 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。

 

<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。

 

 

<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
