Introduction Unit testing is a crucial aspect of software development, allowing developers to verify that individual units of code perform as expected. Mockito is a powerful framework for Java that enables effective unit testing by providing mechanisms to create mock objects, stub methods, and verify interactions between objects. In this guide, we will delve…
Introduction : In Spring Boot, BeanFactoryAware and FactoryBean<Object> are two interfaces that provide additional capabilities for managing beans within the Spring context. BeanFactoryAware allows beans to interact programmatically with the container, while FactoryBean<Object> allows for custom logic when creating beans. In this tutorial, we'll explore how to use these interfaces with examples in a…
Spring Batch is a powerful framework for batch processing in Java applications, and it integrates seamlessly with Spring Boot for building robust and scalable batch processing systems. In this tutorial, we'll cover the basics of setting up a Spring Boot project with Spring Batch and provide examples to help you get started. Prerequisites: Basic…
ThreadLocal is a class in Java that provides thread-local variables. These variables differ from their normal counterparts in that each thread that accesses one (via its get or set method) has its own, independently initialized copy of the variable. This guide will explore the ThreadLocal class, its usage, and provide examples to illustrate its…
Java Records, introduced in Java 14 as a preview feature and finalized in Java 16, provide a concise way to define immutable data carrier classes. They reduce boilerplate code needed for simple data structures by automatically providing implementations for methods like equals(), hashCode(), and toString(), as well as accessor methods for the fields. This…
In Java, decorators are a structural design pattern that allows behavior to be added to individual objects dynamically, without affecting the behavior of other objects from the same class. Decorators are particularly useful when you need to add functionality to objects in a flexible and reusable way. This tutorial will explain the decorator pattern…
1. Introduction to @EnableConfigurationProperties Spring Boot provides a convenient way to bind external configuration properties to Spring beans using the @EnableConfigurationProperties annotation. It enables the automatic binding of properties defined in your application's configuration files (such as application.properties or application.yml) to fields of Spring beans. 2. Creating Configuration Properties First, you need to create…
Introduction : The java.util.Objects class was introduced to address common object-related tasks in a consistent and concise manner. Prior to Java 7, developers had to manually handle certain tasks such as null-checking, equality testing, and hash code calculation, often leading to verbose and error-prone code. The Objects class provides static utility methods that help…
