How to get client IP in Quarkus JAX-RS service @ApplicationScoped?

[dhoffer]

I have tried injecting HttpServletRequest but get CDI build errors. I have tried @context HttpServletRequest in the service method and I get rutime error of RESTEASY003880: Unable to find contextual data of type: javax.servlet.http.HttpServletRequest

How can I get the client IP calling the services?

What errors did you get? It should be possible to @Inject io.vertx.core.http.HttpServerRequest.

Hm, I can see you're trying to use the servlet API. Do you use the undertow extension?

I believe the following is the preferred way if using the reactive libraries:

@Context
io.vertx.core.http.HttpServerRequest httpRequest;

Works for us in @ApplicationScope, @RequestScope and @javax.ws.rs.ext.Provider (e.g. filters).

I was using javax.servlet.http.HttpServletRequest. I just tried @Inject io.vertx.core.http.HttpServerRequest and it seems to work, I'll investigate this more. We are not using reactive JAX-RS libraries, so is @Inject preferred over @context?

Just had this problem myself. Injecting HttpServerRequest would work on the Controller layer, but on on the Service layer, it was a null object. Which is kinda lame, since it appears to lose the context, and i would have to pass this object to every service method that needed this.
Just inject RoutingContext instead. From the routing context you can get the HttpServerRequest by using the RoutingContext.request() function. Good thing about this is that you can inject this into the Service layer as well and will still have all the context, given that the Service was called by a Controller.

Hope this helps!

So this is weird because both the io.vertx.ext.web.RoutingContext and io.vertx.core.http.HttpServerRequest beans are @RequestScoped. In fact, the producer for the latter injects the first one - see also https://github.com/quarkusio/quarkus/blob/main/extensions/vertx-http/runtime/src/main/java/io/quarkus/vertx/http/runtime/CurrentRequestProducer.java#L18-L23. In other words, @Inject should work the same way for both, whereas @Context only works in JAX-RS resources.
