（1）—-SpringSecurity3.2环境搭建
最后更新于：2022-04-01 14:53:54
目前Spring官方只提供Meven的下载方式。但在[http://maven.springframework.org](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/](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-web/3.2.0.RELEASE/)[http://maven.springframework.org/release/org/springframework/security/spring-security/3.2.0.RELEASE/](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>

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
