Context data (MDC)

[Yaytay]

Hi,

I have had issues in the past with it being impossible to get context data from the Vert.x side once in the Resteasy side when implementing a JAX-RS server inside a Vert.x router.
The crux of this was that the Vert.x context is handled by thread-local variables, but the JAX-RS execution does not take place in a Vert.x thread.

The specific use case is taking the Open Tracing data that Vert.x has extracted and making it available to slf4j as MDC.

Does this new implementation have anything that would make this more achievable?

If not, would be open to a PR to enable something to get through?

Thanks.

This project was just pulled out of RESTEasy itself so we can more freely upgrade Vert.x without breaking compatibility on the core of RESTEasy. We have upgrade to Vert.x 5 in this project now.

That said, there hasn't been much changed in terms of how things work. We're more than happy to accept pull requests though :)

I maintain this: https://github.com/Yaytay/vertx-resteasy-helpers
Some of it could be usefully moved to this repo:

• The JaxRsHandler lets you use RestEasy on an existing Vert.x HttpServer.
• The serializers for Vert.x JSON objects.

You're welcome to anything else there too (though other classes may introduce dependencies).
