#SpringCloudFunction #AWSLambda #TechPrimers - แนวปฏิบัติและการใช้ชีวิต
Thank you so much for going step by step mate. I found some code on the web that somehow didn't work on lambda. Cheers for the excellent explanation and not cutting off things!
Thank you for making this video. Request you to please add more videos such as use cases for this kind of function in a serverless architecture or advanced techniques for spring cloud functions.
Very clear explanation! Tks for sharing!
Nice session on Aws with Spring cloud.
Awesome Job!! To make this look so simple.
May I request for the future, a session on how to enhance this to handle exceptions on spring cloud and passing it through API to the user. Like http 4xx or 5xx errors.
Thanks, easy to understand!
Thank you... I was expecting to try out myself....
Good one ajay :). Thank you
Thank you so much!!!

Am facing this exception. Could someone help me out here?
Nice new intro music ;)
It's very useful
Sir Could you please make a video explaining the resources you use to learn or enhance your programming skills
Thank you so much
Thank you very much .... from performance perspective could you please explain how this Lambda services will handle application traffic ? if not how this lambda service will integrate with load balancer in aws to handle the request's ?
trying to call the local APIs using postman but it does not work..any idea y?
-aws jar is not coming for gradle Projects ..Am I missing something in gradle Project
Two excellent videos sir. Now for the next step. Spring Native with GraalVM backing. I see your startup time for the lambda is around 11 seconds. Can we make this native and get the super fast startup times needed for Lmbda's?
Awesome video..please do with azure adapter
Thanks, nice video. This week I am working on task with API gateway/aws lambda. I find it easier to create API in Gateway and create new resources/methods and assign lambda functions for methods. But I think you should create everything with AWS cloudformation templates.
Do you have any experience with AWS CDK ? Could you create video maybe?
How about using SAM and localstack?
please upload one video extension of this project, store the data into amazon dynamodb
Can you provide a gradle version of this project?
Sir will you please an api call in simple jsp page.... Using dynamodb and api gateway without lambda...
How -aws jar got created for you? Since if I create jar it is getting created as a normal jar. Also, Can you please let us know how to trigger the SNS event to lambda using spring cloud functions.
Hey bro .. you’re doing a good job .. one question ... what’s the best way to read 40.000 email from any micoservice ?
Spring Cloud Function with cold start: 13200ms
Spring Cloud Function with hot start: 100ms
Hopefully GraalVM and Spring will reduce the cold start startup time in the future. Otherwise the better options for Lambda will be Java + Dagger, NodeJs or Python.
Ron Hollander plain core Java 8 based lambda having 300 to 400 ms cold start. And yes node is much faster. Spring boot 2.3 improved a lot.
Need plugin code.Anyone help me in getting that
Great explanation. Would have been lost without it. Can you tell me how you did the auto completion for the plugin? My intellij doesn't offer it to me.
I preloaded them using Live Template feature in IntelliJ. You can check my intellij playlist to see tips n tricks in IntelliJ
Thanks for this video. It was great. I found below observations: we have to use Spring cloud function context version 3.0.3 and above. Earlier versions may not work. My maven downloaded the earlier version and it was not working.
I used Lombok for printing the logs to make sure that logs are printed. My request is, Can you please post a video for use cases where the Spring cloud functions can be used effectively and more functions like post, database calls etc. Overall, Big thanks for this video it was good one.
Sure will do mukul
Why create 2 classes AWSLambdaHandler & Hello? Can't it be one class?
Could you please share source code of this example
We can use the java8 code itself in AWS lambda. what is the advantage over in Sping cloud function to deployed in AWS lambda?
It's another framework. That's it. Which is similar to spring boot n has good integrations with spring cloud libraries
@@TechPrimers ThanksT
what is the dev environment i have to set to run it locally?
I got the same question
I am getting ClassNotFoundException, I am generating AWS jar file that I am uploading in Lambda, but still am getting ClassNotFoundException
I'm getting this:
Error loading class com.javadsalgo.serverless.AwsLambdaHandler: org/springframework/cloud/function/adapter/aws/SpringBootRequestHandler: java.lang.NoClassDefFoundError
java.lang.NoClassDefFoundError: org/springframework/cloud/function/adapter/aws/SpringBootRequestHandler
Can you please show this for post function as well
Anirban Roy its there buddy. Check after the get
Ajay Kumar S it's not there
How to have multiple endpoints with a single jar
Amit Prasad FUNCTION_NAME=Endpoint function name. Provide this in environment variable
Hi Friend,
1) You are using Version 1 i.e. com.amazonaws of AWS Java SDK. What dependencies we need use for Version 2 i.e. software.amazon.awssdk?
2) You have added the lambda dependencies but where are you using them in your spring boot app?
Your handler is also extending springbootrequesthandler
Thanks in advance
