How do I setup camel-rest in combination with spring-webflux-netty?

[Alphonse Bendt <al...@gmail.com>]

Hi folks,

Within a Spring boot application I want to use camel-rest as consumer to be able to define rest endpoints:

from(„rest://get/hello-world“).constant(„Some static content“)

This works fine with the spring-boot-starter-web which uses Tomcat:

Get http://localhost:8080/rest/hello-world => 200

Now I was trying to achieve the same with spring-boot-starter-webflux + netty

What I did so far is:
* exchange spring-boot-starter-web with spring-boot-sterter-webflux
* add camel-netty-http
* configured the rest component to use netty-http instead of servlet: getRestConfiguration().setComponent("netty-http“)

I can see in the log output that the route still is being registered however cannot be accessed in the spring application
Get http://localhost:8080/rest/hello-world => 404

I am assuming that a new ServerPort is being opened instead of hooking into the one already provided by spring?

How do i configure things so that the rest endpoint is accessible via the Spring server port? Can anyone show me directions?

Thanks in advance,
   Alphonse

Hi,

Thanks for that. Unfortunately this does not seem to work for me. My steps:

* added dependency to camel-platform-http-starter
* this has a transitive dependency on spring-boot-starter-web and tomcat, so I excluded them from the dependencies
* reconfigure camel-rest: getRestConfiguration().setComponent("platform-http“)

With this configuration I get classnotfoundexceptions while trying to run the springboottests.
java.lang.ClassNotFoundException: org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping

I’ll stick with spring-boot-starter-web and tomcat for now.

Thanks so far!

Hi

Use the platform-http for the consumer - then you use what spring comes
with as http server.
