Which of the following statements accurately describes the use of the @Component annotation in Spring?. The @Component annotation is used to define a class as a controller in the Spring MVC framework, responsible for handling user requests and generating responses. It enables the class to handle HTTP requests and render appropriate views. The @Component annotation is used to mark a class as a Spring bean, allowing it to be automatically detected and registered within the application context for dependency injection. It enables the class to participate in the inversion of control (IoC) and be managed by the Spring container. The @Component annotation is used to enable transaction management in Spring, specifying that a method or class should be executed within a transactional context. It ensures data consistency and integrity by automatically managing database transactions. The @Component annotation is used to configure a data source in Spring, specifying the connection details and access methods for interacting with a database. It provides the necessary configuration to establish a database connection and perform CRUD operations.

Which of the following statements accurately describes the use of the @Repository annotation in Spring?. The @Repository annotation is used to define a class as a controller in the Spring MVC framework, responsible for handling user requests and generating responses. It provides the necessary methods for processing HTTP requests and rendering appropriate views. The @Repository annotation is used to mark a class as a Spring bean, specifically indicating that it represents a repository or data access object (DAO) in the application. It provides data persistence and retrieval operations for interacting with the database. The @Repository annotation is used to configure a RESTful web service endpoint in Spring, specifying the URL mapping and request handling methods. It enables the class to receive and process incoming HTTP requests, providing appropriate responses. The @Repository annotation is used to enable declarative transaction management in Spring, defining the scope and behavior of transactions within the annotated class. It ensures data consistency and integrity for database operations.

Which of the following statements accurately describes the use of the @Service annotation in Spring?. The @Service annotation is used to define a class as a data access object (DAO) in Spring, responsible for interacting with the database and performing CRUD operations. It encapsulates database-related operations and provides an abstraction layer for data persistence. The @Service annotation is used to mark a class as a Spring bean, specifically indicating that it represents a service layer component in the application. It is typically used to encapsulate business logic, handle complex operations, and coordinate interactions between multiple components. The @Service annotation is used to configure a RESTful web service endpoint in Spring, specifying the URL mapping and request handling methods. It enables the class to receive and process incoming HTTP requests, providing the necessary response. The @Service annotation is used to enable declarative transaction management in Spring, defining the scope and behavior of transactions within the annotated class. It ensures atomicity, consistency, isolation, and durability (ACID) properties for database operations.

Which of the following statements accurately describes the use of the @Controller annotation in Spring?. The @Controller annotation is used to mark a class as a Spring bean, indicating that it represents a service layer component responsible for handling complex business logic and coordinating interactions between multiple components. The @Controller annotation is used to define a class as a data access object (DAO) in Spring, responsible for interacting with the database and performing CRUD operations. It encapsulates data persistence and retrieval operations. The @Controller annotation is used to configure a RESTful web service endpoint in Spring, specifying the URL mapping and request handling methods. It enables the class to receive and process incoming HTTP requests, providing appropriate responses. The @Controller annotation is used to enable declarative transaction management in Spring, defining the scope and behavior of transactions within the annotated class. It ensures data consistency and integrity for database operations.

What is the difference between the @Controller and @RestController annotations in Spring? (4). @Controller is used for building web applications using Spring MVC. It is primarily focused on handling user requests, rendering views, and managing the overall application flow. @RestController is used for building RESTful APIs that primarily deal with data exchange. It focuses on providing data in a serialized format (e.g., JSON, XML) and is suitable for building web services. In a @Controller, you need to use additional annotations like @ResponseBody on individual methods to indicate that the return value should be serialized and included in the response body. By default, Spring assumes the return value is a view name. The @RestController annotation itself is a combination of @Controller and @ResponseBody. It automatically serializes the return value of each method to the response body. The @RestController annotation is used to define a class as a lightweight alternative to the @Controller, providing simplified request mapping and response handling without the need for view resolution. Both @Controller and @RestController annotations are used interchangeably to define classes as controllers in the Spring MVC framework. There is no significant difference in their usage or functionality.

What is the definition of dependency injection in software development?. Dependency injection is a technique used to inject dependencies between classes at runtime, reducing the need for explicit dependency management. Dependency injection is a process of automatically resolving dependencies between classes, eliminating the need for manual configuration. Dependency injection is a design pattern that allows objects to define their dependencies and have them provided by an external entity during runtime. Dependency injection is a mechanism for automatically importing external libraries and modules into a project without explicit declarations.
