Spring Bean Scopes: Singleton and Prototype Architectures

Understanding how your application container manages object lifecycles is critical to building scalable, thread-safe Java applications. This course clarifies the fundamental differences between various lifecycle models, focusing deeply on how objects are instantiated, shared, and destroyed. You will transition from guessing how your dependencies behave to confidently configuring them for optimal performance. What you'll learn: Understand the core concepts of dependency injection and bean management; Configure and implement singleton beans for stateless application components; Implement prototype beans for stateful, short-lived operations; Resolve dependency injection issues when mixing singleton and prototype scopes; Apply modern testing patterns to verify bean lifecycle behavior. You will begin by mastering foundational terminology and container mechanics before progressing to step-by-step configuration scenarios and real-world dependency resolution strategies. This course is designed for beginner to intermediate Java developers who want to solidify their understanding of dependency injection frameworks without any prior configuration experience.
