How does the @Qualifier annotation assist in Dependency Injection in Spring?
- It defines a custom scope for a bean.
- It marks a bean as a prototype, ensuring a new instance is created on each request.
- It resolves circular dependencies in the Spring context.
- It specifies the primary bean to be injected when multiple candidates exist.
The @Qualifier annotation in Spring is used to specify the exact bean to be injected when there are multiple candidates of the same type. This helps resolve ambiguity in cases where there are multiple beans of the same type that could be injected. By using @Qualifier with the bean's name, you can explicitly indicate which bean should be injected, ensuring that the correct one is selected. It's particularly useful when you have multiple beans of the same type and need to specify which one should be used for injection.
