Spring AutoWire

Exploring best practices for dependency injection in Spring

  • Spring
  • AutoWire
  • Backend

Today I explored how @Autowired works under the hood in Spring Boot. It’s more than just automatic wiring — it’s a gateway to better modularity and cleaner architecture.

By organizing beans and injecting dependencies mindfully, I realized:

  • You can simplify testing by using constructor injection
  • Spring lets you control scope, lifecycle, and even fallback wiring behavior
  • Circular dependency issues can often be solved by refactoring or @Lazy injection

I’ll continue refining best practices and documenting edge cases. Spring’s magic is less about the annotation — and more about the structure it enables.
