Mastering Spring Framework Fundamentals - Shareability of Beans in an Inversion of Control (IoC) Container

The video tutorial discusses the concept of bin shareability, focusing on service and repository bins. It explains how beans can be accessed independently and the typical structure of a layered application, where controllers interact with services, which in turn communicate with repositories. The tutorial also explores the idea of bean sharing in an e-commerce context, using examples like order fulfillment and historic order services that might share the same repository.

What is the main advantage of bean shareability in a software application?

• It restricts the use of beans to specific layers.

• It enables beans to be accessed independently by multiple services.

• It prevents beans from being shared across different services.

• It allows beans to be accessed only by a single service.

In a typical layered application, which component usually interacts directly with the repository?

• Database

• Controller

• Service

• User Interface

What is the primary role of a controller in a layered application?

• To manage database connections

• To handle user authentication

• To interact with services

• To perform data validation

In the context of an e-commerce application, which service might use the order repository?

• User registration service

• Payment processing service

• Order fulfillment service

• Product recommendation service

What is a potential benefit of having multiple services use the same repository?

• It increases the complexity of the application.

• It requires more resources to maintain.

• It allows for more efficient data management.

• It limits the scalability of the application.
