尽管我配置了属性文件，但仍然收到错误：
blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
我还创建了 @Provider 扩展了 ContainerRequestFilter ，但是它 永远不会到达那里
application.properties
# Configuration file
quarkus.http.port=9090
quarkus.http.cors=true
quarkus.http.origins=http://localhost:4200, localhost:9090
quarkus.http.headers=accept, authorization, content-type, x-requested-with
quarkus.http.methods=GET, OPTIONS

警告是一个很好的指示。
您的配置不正确。
应该是这样的：
quarkus.http.cors.origins=http://localhost:4200,http://localhost:9090
quarkus.http.cors.headers=accept, authorization, content-type, x-requested-with
quarkus.http.cors.methods=GET, OPTIONS
带有cors前缀。
我们现在没有适当的文档，所以最好参考https://github.com/quarkusio/quarkus/blob/master/extensions/undertow/runtime/src/main/java/io/quarkus/undertow/runtime/filters/CORSConfig.java。
