Spring Bean Scopes: How to Use Them Effectively in Your App

The essential guide to bean scopes in Spring

Bean scopes in Spring provide a way to control the lifecycle of beans and determine which components can access the beans. The concept of bean scope is an important part of the Spring framework, and understanding how it works can help you design and implement more effective and efficient applications. In this article, we will explain what bean scopes are, how they are used in Spring, and when to use each scope.

In the Spring framework, a bean is a Java object that is managed by the Spring container. The Spring container is responsible for creating and managing the lifecycle of beans, and it uses the concept of bean scope to determine how the beans are created and managed.
