Goodbye to @Autowired: Completely Removed it From My Spring Boot Code

"For years, @Autowired was one of the most recognizable annotations in the Spring ecosystem. Frustration andConfusion moving from field injection to constructor injection. But in modern Spring development, especially with Spring Boot and newer practices, you'll often hear: In fact, many teams and guides have removed @Autowired completely from their codebases. Let's explore why. 🎉 If you are not a medium member then Click here to read free"

"2️⃣What is @Autowired, and Why did we even use It? Back in the Spring 2.x and 3.x days, @Autowired was the go-to way of wiring up dependencies. You could slap it almost anywhere: On fields → the shortcut every lazy dev secretly loved 🍕 On constructors → the cleanest and most reliable approach 💪 On setter methods: @Componentpublic class OrderService {@Autowiredprivate PaymentService paymentService;public void processOrder() {..."

@Autowired served as a primary annotation for dependency injection in early Spring versions, usable on fields, constructors, and setter methods. Field injection offered a terse shortcut, while constructor injection delivered cleaner, more reliable wiring and clearer immutability. Migration from field injection to constructor injection often caused frustration and confusion for teams maintaining legacy code. Spring Boot and modern best practices favor explicit constructor injection and reduced use of framework-specific annotations. Many teams and guides have removed @Autowired from codebases in favor of constructor-based wiring or framework conventions. Example code shows field-injected PaymentService within an OrderService component.
