Spring Boot Version 3.0.0, GraalVM 22.3.0。
I use GraalVM and Native Image to build a binary execution file.
The http interface annotation @HttpExchange is used in the project.
Reports this error at the start of the project.

If you're experiencing this on mac OS, the following might help.
https://stackoverflow.com/questions/65954571/spring-boot-2-4-2-dns-resolution-problem-at-start-on-apple-m1/67769368#67769368
Please let us know if that resolves the issue for you.

I'm very sorry, my operating system is window10, I think the link you sent can not solve my problem.
Comment From: sbrannen
@violetagg, have you encountered this before on Windows?
Comment From: violetagg
May be this issue https://github.com/oracle/graal/issues/4304 ?
Comment From: tian-qingzhao
I did that, and I still have that problem. But it seems my problems are the same as theirs.
Comment From: violetagg
@tian-qingzhao Did you add also --initialize-at-run-time=sun.net.dns.ResolverConfigurationImpl as they described?
Comment From: tian-qingzhao
Sorry, I didn't add that parameter just now. Now the problem has been solved. Thank you very much for your help!

Thanks, @violetagg, for helping sort this out! 👍
