- @Around
What annotations are used for transitional management?
Transaction Management: @Transactional is used for declarative transaction management.
What annotations are Springboot specific?
Spring Boot-Specific Features: Annotations like @SpringBootApplication, @EnableAutoConfiguration, and @SpringBootConfiguration are specific to Spring Boot and help with auto-configuration, component scanning, and configuration setup.
- @SpringBootApplication
- @EnableAutoConfiguration
- @SpringBootConfiguration
What annotations are used in testing?
Testing: @SpringBootTest, @DataJpaTest, @WebMvcTest, etc., are used to simplify the setup and configuration of tests.
