web.xml：

pytz

根据日志跟踪，它不是源自自己的代码，我认为这是关于web.xml中的一些配置错误，我不确定。

这是如何引起的？如何解决？

1 个答案:

答案 0 :(得分：0)

我遇到了同样的错误，并找到了解决方案。

找出一次导致此错误的过滤器，方法是一次从web.xml中删除过滤器，直到您未收到此错误。

然后在两个<filter><filter-name> and <filter-mapping><filter-name>中重命名该过滤器。请注意，filter-name可以是任何字符串，但是值必须匹配。它不需要与您的过滤器类名称相同，仅<filter-class>与您的类名称相同。

现在尝试运行它，它应该可以工作。现在，您应该能够将过滤器重命名为其原始名称。
