@Qualifier annotation in Spring Boot
The @Qualifier annotation in Spring Boot (and the broader Spring Framework) is used to resolve ambiguity during dependency injection when multiple beans of the same type are available in the application context. It works in conjunction with @Autowired to explicitly specify which bean should be injected, avoiding exceptions like NoUniqueBeanDefinitionException that occur when Spring can't decide between candidates.
