How can CSRF protection be customized or disabled in Spring Security?
- Configure a CsrfFilter bean to customize settings.
- Modify the csrf() method in the HttpSecurity configuration.
- Use the @EnableCsrf annotation to disable CSRF protection.
- Set csrf.enabled property to false in application.properties.
CSRF protection customization or disabling is done by modifying the csrf() method in the HttpSecurity configuration, typically by calling disable() or csrfTokenRepository(). While Option 1 is partially correct, it doesn't encompass all customization options. Options 3 and 4 are incorrect.
The _____ file in Spring Boot can be used to define configuration properties in YAML format.
- application.yaml
- application.properties
- application.yml
- application.config.yaml
In Spring Boot, the application.yaml file is used to define configuration properties in YAML format. YAML is a human-readable data format often preferred for configuration in Spring Boot. While Spring Boot also supports .properties files, they use a different format. Options 3 and 4 are variations of option 1 and do not represent valid Spring Boot configuration file names.
What is the primary role of Spring Cloud in developing microservices?
- Database management
- Frontend development
- Implementing business logic
- Service discovery, load balancing, and more
Spring Cloud primarily facilitates building microservices by providing essential tools for service discovery, load balancing, configuration management, and more. It simplifies the development of microservices-based applications.
In OAuth2, what is the purpose of the Refresh Token?
- To request additional user information.
- To provide client access to protected resources.
- To refresh the access token without user involvement.
- To authenticate the client application.
The Refresh Token's purpose in OAuth2 is to enable the client to obtain a new access token without requiring the user to reauthenticate. It helps maintain the session's continuity by ensuring that the client can access protected resources even after the initial access token expires. The other options are not the primary purposes of the Refresh Token.
The @WebMvcTest annotation in Spring Boot will _____ any @Component, @Service, and @Repository beans by default.
- Annotate
- Disable
- Exclude
- Include
The @WebMvcTest annotation in Spring Boot includes, by default, only the beans annotated with @Controller, @ControllerAdvice, @JsonComponent, and Converter beans. It does not include @Component, @Service, and @Repository beans.
In a Spring Cloud microservices architecture, _____ is primarily used for allowing services to discover each other.
- Eureka
- Feign
- Hystrix
- Ribbon
In a Spring Cloud microservices architecture, Eureka is primarily used for allowing services to discover each other. Eureka is a service registry and discovery server that enables microservices to find and communicate with each other. When a service starts up, it registers itself with Eureka, making it discoverable by other services. Eureka maintains a dynamic directory of available services, allowing for automatic load balancing and failover.
In Spring Security, what is the significance of configuring a global method security, and how does it differ from standard method security configurations?
- Global method security applies only to controllers, whereas standard configurations apply to service classes.
- Global method security configurations apply to all methods by default, while standard configurations require annotation-based security settings on individual methods.
- Global method security is used for securing web pages, while standard configurations are used for securing REST APIs.
- There is no difference between global method security and standard method security.
Configuring global method security allows you to set default security settings for all methods, which simplifies security setup. Standard configurations require you to annotate each method individually for security settings.
The ordering of Auto Configurations can be controlled using the @_____ annotation or property.
- AutoConfigureOrder
- ConditionalOnProperty
- ConfigurationOrder
- Order
The ordering of Auto Configurations can be controlled using the @AutoConfigureOrder annotation or the spring.autoconfigure.order property. This allows you to specify the order in which Auto Configurations should be applied during the application startup process. The lower the value, the earlier the configuration is applied.
Imagine you are working on a Spring Data JPA project where you need to implement complex dynamic queries. How would you approach designing and implementing such queries to ensure maintainability and performance?
- Combine multiple queries into a monolithic query to minimize database communication.
- Use native SQL queries for complex queries to gain maximum performance.
- Utilize the Criteria API for dynamic query generation, which offers type-safety and flexibility.
- Utilize the JPA repository's built-in findAll method and filter results programmatically in your application code.
When dealing with complex dynamic queries in Spring Data JPA, it's recommended to use the Criteria API. It provides type-safety, flexibility, and better maintainability compared to native SQL queries. Combining multiple queries into a monolithic one may hinder maintainability and lead to performance issues due to unnecessary data retrieval. Using the findAll method and filtering in your application code can be inefficient, causing the N+1 select issue.
The _____ annotation in Spring Boot is used to provide global exception handling across all @Controller classes.
- @ControllerAdvice
- @ExceptionHandler
- @RequestMapping
- @ResponseBody
To provide global exception handling across all @Controller classes in Spring Boot, you can use the @ControllerAdvice annotation. It allows you to define global exception handling logic that can be applied to multiple controllers.
