Spring Security配置好了不起作用
配置了spring security,但是跑起来后，好像没经过spring security的过滤器。
解决：
spring security的过滤器映射
<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>
过滤器映射的前面
