No thread-bound request found

在 Spring 框架下使用 filter 引起的一个错误

在 web.xml 配置文件中有如下代码：

<filter>
    <filter-name>LoginRequireFilter</filter-name>
    <filter-class>com.liumapp.DNSBee.filter.LoginRequireFilter</filter-class>
    <init-param>
        <param-name>noCheckPath</param-name>
        <param-value>login;register;nav</param-value>
    </init-param>
</filter>
<filter-mapping>
    <filter-name>LoginRequireFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

很简单的登录过滤器，但是在运行时报出

HTTP Status 500 - No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

的错误。

解决办法：

在上面的 filter 之前加入一段：

<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>
