structs2.0中 web.xml 配置问题

Question

<filter>
  <filter-name>welcomeFilter</filter-name>
  <filter-class>struts2.action.WelcomeFilter</filter-class>
 </filter>
 <filter-mapping>
  <filter-name>welcomeFilter</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>
 
  <welcome-file-list>
    <welcome-file>/welcome/welcome.jsp</welcome-file>
  </welcome-file-list>
如果这样配可以进入filter
但是如果这样 <filter>
  <filter-name>welcomeFilter</filter-name>
  <filter-class>struts2.action.WelcomeFilter</filter-class>
 </filter>
 <filter-mapping>
  <filter-name>welcomeFilter</filter-name>
  <url-pattern>/welcome/*</url-pattern>
 </filter-mapping>
 
  <welcome-file-list>
    <welcome-file>/welcome/welcome.jsp</welcome-file>
  </welcome-file-list>
就进不去！！！！高手指点下小弟
目的是不能直接访问：http://127.0.0.1/wfasd/welcome/welcome.jsp
需要通过过滤器来做个过滤跳转 

Answer 1

 <filter-mapping>
  <filter-name>welcomeFilter</filter-name>
  <url-pattern>/welcome/*</url-pattern>
 </filter-mapping>
<url-pattern>/*</url-pattern>表示structs能过滤处理所有的标签，加一个/welcome就将范围缩小了啊，

Answer 2

struts2.0配置
<filter>
   <filter-name>welcomeFilter</filter-name>
   <filter-class>struts2.action.WelcomeFilter</filter-class>
  </filter>
  <filter-mapping>
   <filter-name>welcomeFilter</filter-name>
   <url-pattern>/*</url-pattern>
  </filter-mapping>web.xml配置
<welcome-file-list>
   <welcome-file>welcome.jsp</welcome-file>
   </welcome-file-list>
这样就行了
