<h2>Introduction</h2>
<p>Welcome to the comprehensive guide on <strong>Spring Beans</strong>—a cornerstone concept in the Spring Framework that enhances the flexibility and maintainability of your Java applications. This eBook delves into the intricacies of Spring Beans, exploring their configuration, benefits, and practical implementation. Whether you're a beginner or a developer with basic knowledge, this guide equips you with the insights needed to streamline your Spring applications effectively.</p>
<hr/>
<h2>Understanding Spring Beans</h2>
<p>In the Spring Framework, <strong>Beans</strong> are the fundamental building blocks that form the backbone of your application. They are objects instantiated, assembled, and managed by the Spring IoC (Inversion of Control) container. Proper configuration of these Beans is crucial for creating a clean, efficient, and scalable application architecture.</p>
<h3>Key Concepts and Terminology</h3>
<ul>
<li><strong>Bean</strong>: An object managed by the Spring container.</li>
<li><strong>IoC Container</strong>: Manages the lifecycle and configuration of Beans.</li>
<li><strong>@Component</strong>: An annotation used to indicate a Spring-managed component.</li>
<li><strong>@Bean</strong>: An annotation used within a configuration class to define a Bean.</li>
</ul>
<hr/>
<h2>Transitioning from @Component to @Bean</h2>
<p>In previous implementations, the <strong>@Component</strong> annotation was extensively used across classes like <strong>Corolla</strong>, <strong>Swift</strong>, <strong>V6</strong>, and <strong>V8</strong>. However, transitioning to using <strong>@Bean</strong> within a centralized configuration class offers significant advantages in terms of manageability and clarity.</p>
<h3>Removing @Component Annotations</h3>
<p>To streamline your application, start by removing the <strong>@Component</strong> annotations from the respective classes. This involves:</p>
<ol>
<li><strong>Deleting @Component Annotations</strong>: Remove the <strong>@Component</strong> annotation from classes such as <strong>Corolla</strong>, <strong>Swift</strong>, <strong>V6</strong>, and <strong>V8</strong>.</li>
<li><strong>Eliminating Unused Imports</strong>: After removing the annotations, delete the associated import statements to clean up the codebase.</li>
</ol>
<pre><code>// Before
public class Corolla implements Car {
// Class implementation
}
// After
public class Corolla implements Car {
// Class implementation
}
|
Introducing @Bean in AppConfig With @Component annotations removed, the next step is to define Beans within a centralized configuration class (AppConfig). This enhances visibility and simplifies Bean management.

}
}

00:00:00,000 --> 00:00:05,000
Hey there welcome back let's continue our journey and in this video we will get started with our first application which we will eventually create a spring application now there are small little steps which I will display and demonstrate in this video so be little cautious and follow my lead alright
2
00:00:05,001 --> 00:00:10,000
So the first thing first you should actually open your eclipse IDE as an admin in that way there are few errors which we will avoid okay so open your eclipse as administrator every time whenever you want to start application development in Windows for example in Mac or in Linux you can sudo and start eclipse or by default you can start eclipse now majorly in Mac and eclipse it should not cause an issue
