Thank you so much for this video, it really helped me out creating my first full functioning web app!

@huw1676 3 месяца назад

This is really good, and exactly what I needed. Thank you for making this straightforward and easy to understand.

Thankyou so much @DenVega. It's my humble request to you pls make a detailed video or series on spring cloud function for serverless programming. Please from love of my heart for such of awesome content always ❤️❤️❤️

@DanVega Год назад

What are you looking for? I have a video that I did in the past on building functions using Spring Cloud Function.

@codertravel99 Год назад

@@DanVega hey hi I'm new to spring cloud function for serverless and I'm working in project where i have to pass objects and perform crud after that I can move also and one more thing that working with se bucket to upload videos or images etc all these are my requirement but I'm not finding any solution if possible then pls help.

@indiraparasa6805 Год назад

@DanVega, very understandable and useful content, I am looking for retrieving secrets from secret manager in init phase, it should not hit for all invokes, how can we handle that

@nb-th7kr Год назад

small note why I think snapstart did not work for you: 18:14 you clicked back to the function instead of testing the snapshot of the function by clicking "test" in the tab. When I tested it for me, cold start time for the function itself was around 2200-3000ms. Cold start time for the snapstart version was 600-800ms

great video guy!!! suggestion try dracula theme from zeno rocha, try use the colorfull variation those fonts in red reminds me to error in somewhere xD but arent errors (just try, dont need change anything just im saying something)

@mertbahadr7678 Год назад

Hey Dan, For the next videos can you open Presentation Mode of Intellij? so we can see your short cuts and learn :) Thank you.

on AWS i just use lambda functions with nodeJS+JS i want to suggest to our team to use java on next sprint, i will suggest this video as example but we are using serverless framework 3 to build lambdas trought github workflow today serverless just create an example with java 8... but as im understanding i just need to build the spring project to create the target folder files and serverless deploy to the magic appear on AWS....

Very appreciate your content!!! You are one of the best Spring teachers in the world! Btw Dan you mistyped "that" in your website on Blog tab

As usual quality content 🙌

@neeraj1905 11 месяцев назад

Thanks Dan. I love watching uour videos. They are very informative… 🙏🙏🙏But my concern is that the real power of springboot is not in coding for some plain functions. Its all about using autowiring of service layer, repository layer, jpa, rest templates and having some endpoints being exposed via controllers. Can we achieve all that with AWS lambda and Springboot.

@Rostik_13 Год назад

Go, go, go!😃

@FMTMoro Год назад

Thank you Dan.

@youtubevideos415 Год назад

This looks so laborious. Isn't there something like the Serverless Framework, so you can upload and test the Lambda function from the command line, like you can with NodeJS or PHP? I don't see myself writing Lambda functions in Java, if i have to constantly have to upload artifacts through my webbrowser to AWS.

@DanVega Год назад

Great question. All of those things exist but this isn't the point of this video. When I'm writing functions using Spring Cloud Function / Spring Boot 3 / Java 17 I can test them locally. You also have access to CDK so you can create/deploy via code and avoid the web console. Just kept it simple for this example

@youtubevideos415 Год назад

@@DanVega Thanks. That's nice to know. I'm new to Java / Spring so i didn't know if those tools exist.

@eiei1975 11 месяцев назад

Great content as usual. Why did u need to add Spring web dependency? Is this is a must for aws lambda? can't I test it on AWS lambda without web dependency?

@sakthinivas1840 6 месяцев назад

Hi Dan, thanks for the great content. Do you know how to test the Lambda function natively on AWS when the application has multiple functions?

@sergiocoder 7 месяцев назад

Could you please also show how to create multiple functions and call them via URL? And if it's possible, how to route the functions to an existing Controller's methods. Thanks!

@baronidev 2 месяца назад

Do you have any course/book to indicate about Java serverless on aws ?

@borisborisov9999 5 месяцев назад

hey @DanVega, if i want to add some query params (assume I am issuing a GET request) to the exposed function url, how can i do that one more thing: if i want to secure that function url?

@yashtrivedi6130 Год назад

I love watching your videos Dan such a great way to represent latest market trend in java Q. Could you please tell how can we keep our lambda active because the first request takes quite a good time to respond

@CK-bu5wh 8 месяцев назад

I think that’s the cold start problem? So you find any way to solve it? I think to way to fix it is to use provision concurrency

@hrsatsangi Год назад

Hey dan what about your course launching or not... We are waiting that course eagerly Please as soon as possible launch that course love from India 🇮🇳

How about adding a S3 trigger with image or mp4 in the event and posting it to an endpoint 😊

@r-rtz 7 месяцев назад

What is that log in AWS Log output showing for the Spring Boot app : "Build-Jdk: 1.8.0_342" ? I thought it supposed to be 17 !!!!

@antoniomaucyrpasqualli6857 Год назад

hi, How to make a post? in the api(test) the error is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize value of type `java.lang.String` from Object value (token `JsonToken.START_OBJECT`) what is wrong?

@user-lu4pf3ld5v Год назад

I don't know if you notice when downloading files from s3 under lambda, the perfromance of jdk11 is much better than jdk17

@sidharthadas241 Год назад

Hey Dan, could you please share the gradle project of the program

@user-zn2ym3qj1v Год назад

it works fine with test, but not when i trying to send request from postman

@avalagum7957 Год назад

Are java lambdas slower to start than python/javascript lambdas or faster or the same?

@DanVega Год назад

I don't know how it compares but with SnapStart its extremely fast.

How do we process a JSON object as event?

@r-rtz 7 месяцев назад

I am not convinced by this stuff, what was the point of that Spring Cloud Fnc artifact at all, you could've done the whole thing in a bare app, this is not taking advantage of anything Spring !!!

you need to replace . with :: before handleRequest
