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() {..."

The @Autowired annotation was historically central to wiring dependencies in Spring. It could be applied on fields, constructors, or setters. Field injection served as a convenient shortcut, while constructor injection provided a cleaner and more reliable approach. Many teams and modern Spring Boot practices have moved away from explicit @Autowired usage and removed it from codebases. Developers experienced frustration and confusion during the transition from field injection to constructor injection. The code example shows a typical field-injection usage where a private PaymentService is annotated with @Autowired inside an OrderService component.
