在调用formfilter中的dofilter时，我遇到了这个问题。我希望它调用下一个过滤器，即.loginfilter，但它既不返回异常也不调用下一个过滤器类。

    <display-name>LoginFilter</display-name>

<filter-mapping>
    <filter-name>LoginFilter</filter-name>
    <servlet-name>action</servlet-name>
</filter-mapping>

<filter-mapping>
    <filter-name>FormFilter</filter-name>
    <url-pattern>/secured/j_security_check</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>FormFilter</filter-name>
    <url-pattern>secured/j_security_check</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>FormFilter</filter-name>
    <url-pattern>/j_security_check</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>FormFilter</filter-name>
    <url-pattern>j_security_check</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>LoginFilter</filter-name>
    <url-pattern>/mainmenu.do</url-pattern>
</filter-mapping>

一旦j_security_检查完成，控件将调用formfilter调用，然后它应该调用loginfilter，它应该被重定向到主菜单。但这不会发生。有谁能给我指路吗。谢谢。
