In this article we will cover the topic of annotations by way of some theory and a brief example using Java 9. We will cover what they are, their properties, their purpose and different types. The example code will demonstrate the application of an annotation processor using custom annotations on an interface to automatically generate a ...

This post is a follow up post to a few that I have written recently relating to writing a HATEOAS service and handling exceptions with Spring (Applying HATEOAS to a REST API with Spring Boot and Global exception handling with @ControllerAdvice). Now that we have looked through setting up a service and how to add ...

One of the most important development principles of the modern software design is the Dependency Injection (DI) which quite naturally flows out of another critically important principle called Modularity. This tutorial will explore a specific type of DI technique within the spring framework called Setter-Based Dependency Injection which simply...

Java 9 delayed so many times because of Project Jigsaw, and you may be heard a lot of thing about modules, modularity, and other stuff, so, what it’s all about? What the heck is modularization and what do we mean by modularized platform? Java Platform Module System (JPMS)? Is it going to be a revolution in ...

This post is based on the common questions raised about registry mounting and how it works etc. Below are the main questions people ask: 1). How mounting works? 2). What is the difference between Config Registry and Governance Registry? 3). Can I use databases other than H2 for Local Registry? 4). What is meant by ...

As described in the previous post, we have four different garbage collectors available in HotSpot JVM. There are some significant differences between them, but the actual concepts behind the algorithms which are used to do the actual job are quite similar. In this short post, I will try to explain three basic algorithms: Mark-sweep...

Reactive Java or RxJava is an implementation and enhancement of the observer pattern. It was intended for use in event driven schemes where nesting synchronous or asynchronous callback methods becomes overly complex. It abstracts some of the more complex tasks associated with asynchronous operations including threading and concurrency. This...
