Java servlet过滤器在登录时不起作用 [英] Java servlet filter not working on login

问题描述

我编写了一个过滤器类来为每个页面添加一个 P3P 标头.我将此添加到我的 web.xml 中:

I've written a filter class to add a P3P header to every page. I added this to my web.xml:

<filter>
    <filter-name>AddP3pHeaderFilter</filter-name>
    <filter-class>com.mycompany.AddP3pHeaderFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>AddP3pHeaderFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

它会在每个页面请求中添加标头，但在用户第一次登录时不起作用.用户将表单提交给j_security_check，但响应不包含标头.如何使我的过滤器适用于登录请求?

It adds the header to every page request, but it doesn't work when the user first logs in. The user submits the form to j_security_check, but the response doesn't include the header. How can I make my filter apply to the login request?
