过滤器的问题?

Question

你的doFilter方法里好象没有这一句嘛
  chain.doFilter(request, response);还有把 
 <filter>
<filter-name>validate</filter-name>
<filter-class>cooloft.disport.com.filter.AdminCheck</filter-class>
</filter>
<filter-mapping>
<filter-name>validate</filter-name>
<url-pattern>/admin/*</url-pattern>
</filter-mapping>放在
 <web-app>
下面

Answer 1

xml那些标签是不是有先后问题啊，把过滤的提前看看
<web-app>
<filter>
<filter-name>validate</filter-name>
<filter-class>cooloft.disport.com.filter.AdminCheck</filter-class>
</filter>
<filter-mapping>
<filter-name>validate</filter-name>
<url-pattern>/admin/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list> <error-page>
<error-code>404</error-code>
<location>/error.jsp</location>
</error-page></web-app>
