In a Spring Security enabled project, which method is used to configure HTTP security?
- configureSecurity()
- configureHttpSecurity()
- secureHttp()
- httpSecurity()
In Spring Security, the method used to configure HTTP security is configure(HttpSecurity http). This method allows you to define security rules for HTTP requests, such as authentication, authorization, and access control. While the other options may sound plausible, configure(HttpSecurity http) is the standard method name for this purpose.
What is the purpose of the @Valid annotation in Spring Boot when used in controller methods?
- It disables validation.
- It defines a new validation rule.
- It validates incoming request data.
- It initializes the Spring Boot application.
When the @Valid annotation is used in Spring Boot controller methods, it serves the purpose of validating incoming request data. This annotation is typically applied to method parameters, such as a @RequestBody, to trigger validation of the request body based on the validation rules defined for the associated class. It ensures that incoming data is valid according to the specified constraints. The other options are not the correct purposes of the @Valid annotation.
In Spring Boot, how do you configure the TestRestTemplate to work with a specific profile during integration testing?
- Use @ActiveProfiles annotation
- Use @SpringBootTest with webEnvironment attribute
- Use @ContextConfiguration with locations attribute
- Use @AutoConfigureTestDatabase annotation
To configure the TestRestTemplate to work with a specific profile during integration testing, you can use the @ActiveProfiles annotation. This allows you to specify which application profile to use when running the tests. The other options do not directly configure the TestRestTemplate for a specific profile.
The @Repository annotation in Spring Boot is particularly useful when working with _____ to interact with the database.
- @EntityManager
- @Service
- @JpaRepository
- @DataSource
The @Repository annotation in Spring Boot is particularly useful when working with @JpaRepository to interact with the database. @JpaRepository is a Spring Data JPA-specific repository interface that provides out-of-the-box CRUD (Create, Read, Update, Delete) operations. While @Service and other options can be used in Spring applications, they are not typically associated with database interaction like @Repository and @JpaRepository.
Which feature of Spring Boot simplifies the inclusion of external libraries or modules?
- Spring AOP
- Spring Cloud
- Spring Data
- Spring Initializr
Spring Boot simplifies the inclusion of external libraries or modules through Spring Initializr. Spring Initializr is a web-based tool that generates the project structure with the required dependencies based on your selection. It makes it easy to bootstrap a Spring Boot project with the necessary dependencies without manually managing configuration files.
How does WebFlux differ from the traditional Spring MVC framework in handling HTTP requests?
- Spring MVC uses a reactive programming model.
- Spring MVC uses a servlet-based architecture.
- WebFlux is asynchronous and non-blocking.
- WebFlux is single-threaded and blocking.
WebFlux differs from traditional Spring MVC by being asynchronous and non-blocking. In WebFlux, it handles requests reactively, meaning it can efficiently manage a large number of concurrent connections without blocking threads. On the other hand, traditional Spring MVC relies on a servlet-based architecture, which is typically blocking, making it less suitable for high-concurrency scenarios.
