At the bare minimum, every Java developer should be familiar with JUnit and Mockito, two of the most popular Unit testing and Mock library. While learning Spring Boot and Spring Cloud is sufficient for developing Microservices in Java, there is a couple of more advanced frameworks you can explore, like Eclipse’s Microprofile, Micronaut, and Quarkus. It provides some of the essential features like Caching and Transaction out-of-the-box, which means you have more time to focus on your application logic, than implementing caching in your application. This seriously improves the performance of Java applications, and so far, my most significant reason to use Hibernate. Well, because most of the Java applications you will work with will interact with Database, and it’s excruciating to deal with Database in Java using JDBC and without a proper framework like Hibernate.
It’s a Kubernetes Native Java stack tailored for OpenJDK HotSpot and GraalVM, crafted from the best-of-breed Java libraries and standards. Quarkus tailors your application for GraalVM and HotSpot to get Amazingly fast boot time and incredibly low RSS memory (not just heap size!).
