Question

在我的web.xml

中考虑以下过滤器映射

<filter-mapping>
    <filter-name>rememberMeCookieFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>mustBeSignedInFilter</filter-name>
    <url-pattern>/private/*</url-pattern>
</filter-mapping>

据我所做的测试，如果我转到/private/account.jsp，必须首先执行mustBeSignedInFilter（from what I could read, it's because the path is more specific）。我需要先记住rememberMeCookieFilter。

我该怎么做？

您将过滤器映射与servlet映射混淆。与URL匹配的所有过滤器的执行顺序与在web.xml中指定过滤器映射的顺序相同。因此，交换过滤器映射，它将按预期工作。

<filter-mapping>
    <filter-name>mustBeSignedInFilter</filter-name>
    <url-pattern>/private/*</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>rememberMeCookieFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

强制首先执行“WebFilter”
