配置了spring security,但是跑起來後，好像沒經過spring security的過濾器。
解決：
spring security的過濾器對映
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/j_spring_security_check</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
一定要在struts的
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
過濾器對映的前面
