The process of injection spring bean dependencies while initializing it called Spring Bean Wiring.
Usually, it’s best practice to do the explicit wiring of all the bean dependencies, but the spring framework also supports auto-wiring. We can use @Autowired annotation with fields or methods for autowiring byType. For this annotation to work, we also need to enable annotation-based configuration in spring bean configuration file. This can be done by context:annotation-config element.
