我在 Jetty 中运行我的 servlet 应用程序，它有时会输出如下所示的堆栈跟踪。我认为这意味着它正在接收无效的 URL 请求，但我实际上看不到该请求。我可以在这里处理这个异常，以便我的日志不会被这个讨厌的堆栈跟踪堵塞吗？如果可以，它可以在我的代码中处理，还是在获取我的代码之前发生此错误，因此需要使用 Jetty 配置来处理？

编辑 因此，如果我确实移至 Jeety 9，我该如何配置它以便堆栈跟踪继续运行，我是否可以配置合适的 http 响应代码

或者，我意识到码头在http://tukey.org/urlrewrite/处理后正在接收请求，如果生成的 url 无效，我应该在 UrlRewriteFilter 中配置什么来做其他事情。

编辑 有人建议，也许这可以在我的 tukey 配置中处理，所以这就是它目前的样子

<?xml version="1.0" encoding="utf-8"?>

<urlrewrite use-query-string="true">
    <rule>
       <note>
           Matches urls like http://localhost:8080/ws/1/artist/?query=blur&amp;fmt=xml

     </rule>

    <rule>
        <note>
            The rule means that requests to /test/status/ will be redirected to /rewrite-status
            the url will be rewritten.
        </note>
        <from>/test/status/</from>
        <to type="redirect">%{context-path}/rewrite-status</to>
    </rule>


    <outbound-rule>
        <note>
            The outbound-rule specifies that when response.encodeURL is called (if you are using JSTL c:url)
            the url /rewrite-status will be rewritten to /test/status/.

            The above rule and this outbound-rule means that end users should never see the
            url /rewrite-status only /test/status/ both in their location bar and in hyperlinks
            in your pages.
        </note>
        <from>/rewrite-status</from>
        <to>/test/status/</to>
    </outbound-rule>
</urlrewrite>

为此异常编写一个 log4j 过滤器。
