Java Web App with Quarkus and JPAStreamer – Tutorial

In this course, you'll learn how to use Quarkus and JPAStreamer to build a REST web application. Quarkus is an open-source framework tailored for Java, optimized for building speedy cloud-native microservices and serverless applications, especially in containerized environments like Kubernetes. JPAStreamer, on the other hand, is a Java library that simplifies database interactions by allowing JPA entities to harness the expressiveness of Java Stream operations.

✏️ Julia Gustafsson developed this course.

🏗️ Speedment and Quarkus provided a grant to make this course possible.

Great demo with a mix of interesting utilities and libraries. Thanks so much !

[tineshsakthir]

Need more java contents on free code camp

[WaterOfPanela]

Can't wait for the Java 21 version of this tutorial

[jespernielsen]

Thank you so much.

Huge credit. Some time ago, i requested a Quarkus tutorial and here it is. Love the channel.

[montanajava]

Very well presented indeed, thanks! I have been using Quarkus in a work setting for about 2 years now. Now looking forward to adding jpastreamer to the arsenal.

[kevinoliveros]

Im excited bout this course, looks so useful, we need more Quarkus content

[theencryptedpartition]

Dude, been looking for this for a long time now 😂, now it's kinda late cuz I started using Codename One framework, but still pretty cool tutorial! Thanks

[YannikSimon]

Julia did an absolutely incredible job doing this tutorial! Does she have more tutorials for Quarkus somewhere?

[jo]

Please post more java related content like this

[henrique-borba]

That's amazing! It looks like Entity Framework with lambda queries in C#

[jamerson-souza]

49:55 I believe that your update of the records did not work because we used the Http Verb GET instead of PUT, when testing without using GET it worked perfectly.

[MrRhainer]

Explicações com exemplos fáceis de compreender. Obrigado pelas valiosas informações!

[godwin.k]

Thanks ! Since the time I’m waiting for one Java course . Can we have JakartaEE too ?

[curiosidadesdogabriel]

We'd like to see more content about Quarkus and Java development.

[swallowedinthesea]

I thought you were April Wilkerson! Like switching from woodwork to code!

[Skiamakhos]

Hold on, you can use Spring with Quarkus? This sounds good. Does Quarkus take the place of Spring Boot or something?

[tokyofrostgang]

Nice tutorial... thank you... would of been much better if intellij ultimate tools weren't used =)

[ShashwatAnand]

Nice Tutorial, but I think generation of JPAStreamer Meta model is not happening with gradle.
