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"?>
