CDI Support for the Jersey/JAX-RS container?

[dasniko]

Ok guys, this is really awesome!
Thanks for doing this.

I've got the Spring integration up and running in minutes. It really works like a charme with all the Spring functionality included like autowiring etc.

The Jersey/JAX-RS integration also works quite good, but I would love to see some CDI support here as well. Is this somehow possible to provide a simple/small/lightweight CDI integration with Weld, Guice or something similar?

thx + regards,
Niko

Hi Niko,

Thanks for the compliments and feedback. I will look into this. To help us narrow down the scope for a first release, is there something specific you are looking for? Could you give us some mock code of how you would like your tests to work like?

Hi @sapessi,
thanks for your quick reply.

Meanwhile, I started to implement the aws-serverless-java-container-jersey with some jersey-weld2-se here: https://github.com/serverlessbuch/lambda-jaxrs-cdi
(this is the repository for my upcoming book on serverless computing, but german-language only)

However, the unit-tests work fine, even with CDI.
But as soon as I run it on AWS Lambda (through API Gateway), I run into a timeout and get some long logs. Currently I've no real idea what this might be. Perhaps you can test my implementation and reproduce the behaviour? Then, we can go any further with my example as a start!?

I got my example now working with Weld as CDI implementation.
This works very well, but I have to build it with Gradle. As soon I build it with Maven, Weld won't work.

Yet, I don't know why this occurs, but I keep investigating and will compare classpaths...

Let me know how it goes. I'll pick this issue up after I've added support for the Play framework.

With the help from @bbilger, who has a similar project as yours https://github.com/bbilger/jrestless we found the solution in proper configuration of beans.xml, @...Scoped annotations and extended maven-shade-plugin: bbilger/jrestless-examples#9 (comment)

I've updated my above mentioned project and it's working pretty good.

[sapessi]

ah, good to hear. I'll keep this open to see if there is something we can include in the project to make the process easier. If not, I'll at least update the wiki to document this.

In the 1.0 release of the library, we updated Jersey to 2.6. The latest version of Jersey can support multiple CDI methods. Resolving this.
