Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

Dubbo Java 3.3.0, OpenJDK17 , Windows 10

Steps to reproduce this issue

https://cn.dubbo.apache.org/zh-cn/overview/mannual/java-sdk/reference-manual/protocol/tripe-rest-manual/#cors%E9%85%8D%E7%BD%AE-2

According to the configuration mentioned in the documentation above

allowed-origins、allowed-methods field in org.apache.dubbo.config.nested.CorsConfig Which are java type of String[] do not take effect, so the dubbo service can not get the corresponding CorsConfig value. But allow-credentials、max-age can take effect。

I reviewed the code of org.apache.dubbo.config.AbstractConfig(the red rectangle)，none of condition can match. So no value will return when class field type is String[] .

Even fix problem above, I think it is not work. Http1UnaryServerChannelObserver rebuild the metadata(Header),so whatever the header is set in Filter, are not send to client.

Anything else
