A. @Configuration This annotation indicates that the class has @Bean definition methods and may be processed by the Spring container to generate bean definitions and service requests for those beans at runtime. B. @ComponentScan This annotation configures component scanning directives for use with @Configuration classes. Provides support parallel with Spring XML's context:component-scan element.

B. Multiple arguments can be injected into a single method using @Autowired.

This is true because the @Autowired annotation can be applied to methods with arbitrary names and multiple arguments, as shown in the example in Using @Autowired.

C. By default, if a dependency cannot be satisfied with @Autowired, Spring throws a RuntimeException.

This is true because the @Autowired annotation has a required attribute that is true by default, meaning that the dependency is mandatory. If Spring cannot find a matching bean to inject, it will throw a BeanCreationException, which is a subclass of RuntimeException. To avoid this exception, we can set the required attribute to false, which will allow Spring to skip the injection if no matching bean is found

A. It causes Spring Boot to enable auto-configuration by default.

This is true because the @SpringBootApplication annotation includes the @EnableAutoConfiguration annotation, which enables Spring Boot’s auto-configuration mechanism1. Auto-configuration attempts to automatically configure your Spring application based on the jar dependencies that you have added2.

B. Component scanning will start from the package of the class.

This is true because the @SpringBootApplication annotation includes the @ComponentScan annotation, which enables component scanning on the package where the application is located1. Component scanning allows Spring to automatically detect and register beans annotated with @Component, @Controller, @Service, @Repository, etc3.

B. The classes are eligible for handling requests in Spring MVC.

This is true because the @Controller annotation marks a class as a web request handler, and it is typically used with the @RequestMapping annotation to map specific URLs to methods1. The @Controller annotation also allows the class to be recognized as a Spring-managed component through the classpath scanning2.

E. The @Controller annotation is a stereotype annotation like @Component.

This is true because the @Controller annotation is a specialization of the generic stereotype @Component annotation, which allows a class to be recognized as a Spring-managed component3. The @Controller annotation extends the use-case of @Component and marks the annotated class as a business or presentation layer4.

Spring and Spring Boot provide various annotations and utilities to support testing of different layers of the application. To create an ApplicationContext for integration tests, we can use either @SpringBootTest or @SpringJUnitConfig annotations. The former is a specialized annotation that also provides additional features such as auto-configuration, web environment emulation, and test properties management. The latter is a general-purpose annotation that combines @ContextConfiguration and @ExtendWith(SpringExtension.class) annotations.

To perform slice testing, which focuses on testing a specific layer or feature of the application in isolation, we can use annotations such as @WebMvcTest, @DataJpaTest, @RestClientTest, etc. These annotations will only load the relevant beans for the tested slice and mock or stub the other dependencies.
