Upgrading Spring Boot and the Spring Health Assessment Report

The video is an informative guide on why and how to upgrade Java projects from Spring Boot 2.6 to 3.2.2. The host, DaShaun Carter, a Spring Developer Advocate at Broadcom, starts by emphasizing the obsolescence of Spring Boot 2.6 and Java 8, demonstrating that new projects cannot be started with these versions on start.spring.io. He then proceeds with a live demonstration where he runs a project on Java 8 and Spring Boot 2.6, highlighting its limitations, particularly in memory usage.

DaShaun showcases the process of upgrading to Spring Boot 3.2, emphasizing the significant improvements in performance and memory usage. The upgrade involves using OpenRewrite recipes, leading to a transition to Java 21. He further explores the benefits of building a native image with GraalVM and Spring's AOT processing, which results in even more efficient memory usage and faster startup times.

The video also includes a demonstration of the Spring Health Assessment Report, comparing the health of the application before and after the upgrade. The post-upgrade report shows a significant improvement, with all green indicators. DaShaun concludes by encouraging viewers to utilize the Spring Health Assessment tool for their projects, offering his assistance and highlighting the ease and benefits of upgrading to the latest Spring Boot version.
