一、配置过滤器代理

          在web.xml中添加SpringSecurity过滤器代理：

            

[html] view plaincopy

        <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>  

         在classpath下添加spring-security.xml配置文件(名称自定)  ， 在此配置文件中添加springSecurity命名空间。

             

[html] view plaincopy

<?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-3.1.xsd  

                        http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd">  

  

</beans:beans>
