Upgrading your Java & Spring Boot applications with OpenRewrite in IntelliJ

In this tutorial we will take a look at a project called OpenRewrite that allows you to automate your upgrades. We are going to look at the newly bundled plugin in IntelliJ for running your recipes right in your IDE. We will look at both a simple Java example and then how to upgrade a Spring Boot 2.7.x app to 3.0.

Thanks, Dan! I had not heard about the IDEA plugin. Two quick thoughts:
1. For a complex application I would suggest to migrate to Java 17 on 2.7.18 first, then to 3.0 and so on.
2. One of the recipes will add the new property to enable virtual threads. You may need to already use Java 21 to trigger it.

Hey Dan, thank you for your videos. I have a question what is your opinion on Mono repos?

[@HappyTest-rr3jq]

hi! can you make a video on fundamentals of annotation processing in java, correlating with spring annotations.

Hi Dan, thanks for the video.
I'm currently migrating an application from Spring Boot 2.7 to 3.0 and I am struggling with Hibernate 6 which, as a full JPA provider, does not support nested transactions anymore and this is a requirement for us as we are using save points. Is there a way to replace the save points with a similar mechanism using Hibernate 6 as a JPA provider ?
Thanks and keep up with the great work!

I've covered the basics like REST client, security, tests, I'm eager to know what additional skills and knowledge I should acquire to become proficient in Spring Boot and adequately prepared for a junior-level role. Could you make a video where you would outline the essential Spring Boot topics and concepts I should master to be job ready? I believe many people here are in a similar situation, trying to learn Spring Boot but unsure of what else they should master within the Spring framework.

[@immortal-spirit-13]

Thanks 😀 Interesting, but I think very difficult

[@marouaniAymen]

I remember that you did video before about a similar tool, or is it ? I think that under the hood this tool relies on JavaParser, right ?

[@ataturkoglu9686]

Thanks Dan. I have spring 4 project and i want to migrate it to spring boot 3. I've always seen spring boot x.x to spring boot x.x. Can openrewrite do this migration(Spring 4 to Spring Boot 3) ?

Hi Dan, Could you please make a video to remove the unused maven dependency from pom.xml in spring boot application . It will be helpful. Thank you.
