🚀 Spring Boot Conditional Bean Injection — The Feature Most Developers Don’t Know ✅

In this video, we explore Conditional Beans in Spring Boot and how they help you create clean, flexible, and modular applications without writing messy if-else logic. Spring Boot provides powerful conditional annotations that allow beans to be created only when certain conditions are met. This is the same mechanism used internally by Spring Boot Auto Configuration. You’ll learn how to use several important conditional annotations including: @ConditionalOnProperty @ConditionalOnBean @ConditionalOnMissingBean @ConditionalOnClass @ConditionalOnExpression Custom conditions using @Conditional Through practical examples, you'll see how Spring Boot decides which beans should exist in the Application Context and how this approach can simplify configuration and feature management in real-world applications. Whether you're building feature toggles, environment-specific services, or optional integrations, conditional beans are an essential tool for every Spring Boot developer.
