SpringBoot is the most widely used application framework in Java, but did you know you can your SpringBoot 3 applications built with Java 21 on AWS Lambda in under 10 minutes.
In this video you will dive into taking a brand new SpringBoot 3 API and deploying that to AWS Lambda in under 10 minutes. Then, you will enable Lambda SnapStart to improve the performance of your SpringBoot Lambda functions at startup.

This is exactly the type of content I need right now. I am a little under a month with AWS and the only thing I am struggling with is connecting all the services together. Things like having a EC2 instances in private and public subnets and connecting them together. Also architecture design. I understand your mainly a severless Java channel, so I'll probably have to figure it out some other way if you can't do it.

@serverlessjames 8 ай бұрын

Glad to hear it. Yeah, the content is mainly serverless. One reason being you don't need to worry about EC2 instances and subnets. Is there any other content you'd like to see that would be helpful to your journey?

Hi James thanks for putting this video together. For me the next steps are to learn how to do local debugging using SAM, adding authorizers, and deploying with stages thru pipelines. Looking for more tutorials on how to do these things.

@serverlessjames 8 ай бұрын

Sure, I can do that. But it's as simple as defining Spring routes in the same way you always would with Spring ☺️ any tutorial on the internet talking about Spring would work. I'd highly recommend Dan Vega's Spring tutorial as a starting point.

Love the content. Can you make a demo video but deploying this app as a GraalVM native image? If possible setting up a pipeline since we would have to use a custom runtime.

Yeah absolutely. GraalVM has been on my list to look into for a little while now anyway 👌☺️

Is there code to create the subnets and VPC's, instead of going thro the prompts and creating them? Looking forward to see how you have configured VpcConfig section. Do we need to setup networking outside this example or the SAM prompts create the required networking also?

@serverlessjames 7 ай бұрын

So this code doesn't actually interact with any VPC resources, so it isn't covered here. Typically I would recommend creating your network resources separate from your application stack. And then you'd specify the subnets and security group ID as part of your SAM template in the VPCConfig section.

Hi James! Thank you for the video, I was curious if you could help me troubleshoot here, I am not getting the outputs to appear but the deployment says it was succesful i just do not know how i am supposed to verify this being the case without seeing the outputs, any advice welcome! Thank you!

Dear James, thx a lot for that video. Very helpful indeed. 👌May I ask for a big favor? 🙏🏼Would it be possible for you to lay out a springboot3 app in lambda with an api gw in front of it which does session handling in redis and maybe stores a simple object in a relational database - something like Postgres - and for the infrastructure as code I would love to see the usage of cdk instead of sam. Do you think that would be possible? Thx a lot in advance. If not in a complete video maybe some guides, hints or further links would also be highly appreciated. Regards, Mario 🎉

If you run a 'sam init' command and go through the quick start wizard, select Java21 and that will give you an example 👍☺️

hey @serverlessjames Thanks a lot for this tutorial i have implemented a similar this in my company just have a doubt in this , Does this support multipart file also in controller for ex( @RequestPart(value = "zipFile", required = true) MultipartFile zipFile) will this work if i add this controller and call using serverless lambda . Waiting for your reply i am stuck in this for 1 week now .

@serverlessjames 4 ай бұрын

That's a great question that I don't actually know the answer to. I think you'd have to make some changes in API Gateway to allow the different content type. But I see no reason why it wouldn't work

I believe you are using API Gateway infront of your Lambda to recieve the request and proxy the request. Is there a way we can implement a handler class which does not use API Gateway? I want to invoke my springboot controller method directly from my handler class without proxying the request.

If you were going to do that you probably wouldn't need Spring boot at all?
