写了过滤器以后的登陆页面图片和css被过滤

Question

都被过滤了我的解决方案在web.xml中是这一样写
<init-param>
<param-name>notCheckURLList</param-name>
<param-value>/web/LoginServlet;/web/login.jsp;/web/images/station.jpg;/web/images/TOPBAR.GIF;/web/images/login_sign.jpg;/web/images/btn_login.GIF;/web/images/btn_register.GIF;/web/css/stylesheet.css;/web/patientRegister.jsp;web/PatientRegister;/web/PatientNameEServlet</param-value>
</init-param>
然后再filter中处理
奇怪的是我写/web/css/*或这/web/css/*.css都不能放行 图片也是 
这个怎么解释啊

Answer 1

LZ把过滤器过滤对象 写成*.*了吧<filter-mapping>
<filter-name>**Filter</filter-name>
<url-pattern>*.*</url-pattern>
</filter-mapping>

Answer 2

把代码贴出来web.xml中
</filter>
<filter-mapping>
<filter-name>setEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
 
<filter>
<filter-name>checkLogin</filter-name>
<filter-class>hospital.filters.LoginFilter</filter-class>  
<init-param>
<param-name>redirectURL</param-name>
<param-value>/web/login.jsp</param-value>
</init-param>
<init-param>
<param-name>checkSessionKey</param-name>
<param-value>loginName</param-value>
</init-param> <init-param>
<param-name>notCheckURLList</param-name>
<param-value>/web/LoginServlet;/web/login.jsp;/web/images/station.jpg;/web/images/TOPBAR.GIF;/web/images/login_sign.jpg;/web/images/btn_login.GIF;/web/images/btn_register.GIF;/web/css/stylesheet.css;/web/patientRegister.jsp;/web/PatientRegister;/web/PatientNameEServlet;/web/images/btn_cancel.GIF;/web/PatientNameEServlet</param-value>
</init-param>
</filter>

Answer 3

 <filter-mapping>
    <filter-name>setEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
    </filter-mapping>
改成
 <filter-mapping>
    <filter-name>setEncodingFilter</filter-name>
    <url-pattern>*.do(*.jsp)</url-pattern>
  </filter-mapping>

Answer 4

能不能解释下 要改的是登陆的filter 为什么要改转码的filter？

Answer 6

HttpServletRequest req = (HttpServletRequest) request;
String reqPath = req.getServletPath();
if (!reqPath.endsWith("css"))
这样试试
