Mastering Spring Framework Fundamentals - Verifying the Annotation-driven Auto Wired Beans

The video tutorial explains how to replace XML-based bean definitions in Spring with Java annotations. It covers component scanning, the use of @Autowired for dependency injection, and the creation of beans within the Spring context. The tutorial also demonstrates debugging and executing methods, highlighting the benefits of using annotations for cleaner and more efficient configuration.

What is the primary role of the application context XML in Spring?

• To manage database connections

• To initiate the component scan

• To handle user authentication

• To configure network settings

How does the @Autowired annotation function in Spring?

• It deletes unused beans

• It updates existing beans

• It creates new beans

• It injects available beans into the application context

What is the scope of a Singleton bean in Spring?

• It is created once per application context

• It is created once per user session

• It is created once per HTTP request

• It is created once per method call

What is one advantage of using Java annotations over XML for bean definitions?

• It provides a cleaner and more efficient configuration

• It is less flexible

• It requires more lines of code

• It is harder to maintain

What remains unchanged when switching from XML to Java annotations for bean definitions?

• The location of beans

• The type of beans

• The number of beans

• The scope of the beans
