When a Spring Boot application starts, Kafka Listener’s default behavior is to begin listening for a certain topic. However, there are situations when we don’t want to start it right away once our application launches....

Dependency Injection (DI) is essential for improving code modularity, maintainability, and testability in the context of sophisticated Java programming. Choosing between private and private-final injection for dependencies is a typical DI concern. We will examine the distinctions between these two strategies in this post, as well as their applications and ramifications....

UUIDs (Universally Unique Identifiers) are commonly used as primary keys in databases. Because they provide a unique identifier across different systems without relying on a centralized authority. In a Spring Boot application, you can use UUIDs as primary keys for your entities....

In a Spring Boot project, we have to test the web layer. For that, we can use MockMVC. In this tutorial, let us see how to do that by having a sample GeekEmployee bean and writing the business logic as well as the test cases for it....

AOP(Aspect Oriented Programming) breaks the full program into different smaller units. In numerous situations, we need to log, and audit the details as well as need to pay importance to declarative transactions, security, caching, etc., Let us see the key terminologies of AOP...

The World is Moving Towards Microservices Architecture. Yes, it’s true but why? Microservices are becoming more popular day by day. To know Why the World is Moving Towards Microservices Architecture you must refer to this article. This will give you a complete idea of why big organizations like Google, Meta, Twitter, etc. are using Microservices nowadays....

Aspect-oriented programming(AOP) as the name suggests uses aspects in programming. It can be defined as the breaking of code into different modules, also known as modularisation, where the aspect is the key unit of modularity. Aspects enable the implementation of crosscutting concerns such as transaction, logging not central to business logic without cluttering the code core to its functionality. It does so by adding additional behavior that is the advice to the existing code. For example- Security is a crosscutting concern, in many methods in an application security rules can be applied, therefore repeating the code at every method, defining the functionality in a common class, and controlling were to apply that functionality in the whole application. In this article, we will be covering a working example of Around Advice....

Spring Boot is a microservice-based framework and making a production-ready application in it takes very little time. Spring Boot is built on the top of the spring and contains all the features of spring. And is becoming a favorite of developers these days because it’s a rapid production-ready environment that enables the developers to directly focus on the logic instead of struggling with the configuration and setup....

Spring Boot is heavily attracting developers toward it because of three main features as follows:...

Apache Kafka is a publish-subscribe messaging system. A messaging system lets someone is sending messages between processes, applications, and servers. Broadly Speaking, Apache Kafka is software where topics (A topic might be a category) can be defined and further processed. Applications may connect to this system and transfer a message onto the topic. A message can include any kind of information, from any event on your Personal blog or can be a very simple text message that would trigger any other event. Read more about Kafka here. In this article, Spring Boot Kafka Consumer Example we have discussed how we can consume messages from Kafka topics with Spring Boot. But in a complex program, we need to consume JSON objects from Kafka topics....
