我已使用以下 web.xml
文件在 TomEE Web 服务器中启用了 CORS:

自此更改以来,我的所有路线都从同一来源以及另一个来源返回 404。有谁知道这可能是什么原因造成的? 我还尝试了这里最基本的 TomEE cors 过滤器:https://enable-cors.org/server_tomcat.html但这只会导致相同的结果。
提前致谢。
请您参考如下方法:
您是否打算设置metadata-complete="true"
?它会停用一些扫描,因此您可能希望将其保留为 false
您在服务器上部署了什么?这个 web.xml 没有 servlet,所以我猜它应该是扫描过的东西?
