Spring Framework Master Class - Java Spring the Modern Way - Step 18 - Container and Dependency Injection (CDI) - @Named

The video tutorial introduces Context and Dependency Injection (CDI) and its role in Java EE, comparing it with the Spring Framework's dependency injection. It explains CDI's standardization of annotations like @Inject and @Named, similar to Spring's @Autowired and @Component. The tutorial provides a step-by-step guide to setting up CDI in a project, creating a simple CDI example, and demonstrates the use of CDI annotations. It concludes with a discussion on the choice between CDI and Spring annotations, emphasizing CDI's flexibility as a Java EE standard.

What is the primary goal of Context and Dependency Injection (CDI) in Java EE?

• To enhance database connectivity

• To provide a new programming language

• To standardize dependency injection

• To replace the Spring Framework

Which annotation in CDI is equivalent to @Component in Spring?

• @Named

• @Qualifier

• @Singleton

• @Inject

What is the first step in setting up CDI in a project?

• Creating a new Java class

• Adding CDI dependencies in pom.xml

• Configuring a database

• Writing a test case

In the CDI setup, what is the group ID used for the CDI dependency?

• org.springframework

• org.hibernate

• javax.inject

• com.google.inject

What is the purpose of the @Inject annotation in CDI?

• To start a new thread

• To create a database connection

• To inject dependencies

• To define a new class

In the simple CDI example, what is the role of the DAO class?

• To perform network operations

• To manage data access

• To handle user input

• To render UI components

What is a key advantage of using CDI over Spring annotations?

• CDI is easier to learn

• CDI has more features

• CDI is a Java EE standard

• CDI is faster

Why might developers choose to use CDI annotations in a Spring project?

• To adhere to Java EE standards

• To reduce code size

• To improve security

• For better performance

What flexibility does CDI offer if you decide to switch away from Spring?

• It allows for easier database migrations

• It enhances network communication

• It provides a standard set of annotations

• It simplifies UI development

What is the main consideration when choosing between CDI and Spring annotations?

• Cost of implementation

• Availability of documentation

• Standardization and flexibility

• Performance differences
