Review: OpenJDK Migration for Dummies

Fri, 15 Sep 2023 18:46:59 +0000

Have you been thinking of moving away from the Oracle JDK to OpenJDK? The book “OpenJDK Migration for Dummies”, written by Simon Ritter of Azul, provides direction for those who are looking to make the move.

Oftentimes, as long as the application continues running without issue, organizations wouild not upgrade the JDK. As we well know, as with all software, as time goes on, the JDK which is in use can age and become out-of-date, exposing security vulnerabilities. Moreover, if the JDK in use is aging, then there likely have been many enhancements in more recently released JDKs which could provide performance benefits for the deployed application(s).

In this example, I will create a Web Service that will read the current temperature from a file and make it available to clients via a RESTful endpoint.

1. Use the Spring Intializr

The Spring Initializr helps one to choose the dependencies that are required for production a particular solution.
