A bean definition profile is a named logical grouping of bean definitions that can be activated or deactivated in different environments. For example, we can define different profiles for development, testing, and production environments. Spring provides the @Profile annotation to mark a bean definition or a configuration class as belonging to a specific profile. To activate a profile, we can use the spring.profiles.active property or the ConfigurableEnvironment.setActiveProfiles() method.

The @ActiveProfiles annotation is a class-level annotation that is used in conjunction with the Spring TestContext Framework to declare which profiles should be active when loading an ApplicationContext for an integration test. This annotation can be applied to any class annotated with @ContextConfiguration or a meta-annotation that is composed of @ContextConfiguration.

Spring Boot provides a set of tools for improving the development experience, such as automatic restart, live reload, remote debugging, etc. These tools are included in the spring-boot-starter-devtools dependency, which can be added to the project's pom.xml or build.gradle file.

Spring Boot provides a convenient way to create Spring MVC applications with minimal configuration. By default, it uses Tomcat as the embedded servlet container, but it also supports other containers such as Jetty and Undertow. To use a different container, we just need to exclude the spring-boot-starter-tomcat dependency and include the corresponding starter for the desired container. For example, to use Undertow, we can add the following dependencies in our pom.xml:

<dependency> <groupId>org.springframework.boot</groupId> spring-boot-starter-web <exclusions> <exclusion> <groupId>org.springframework.boot</groupId> spring-boot-starter-tomcat </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework.boot</groupId> spring-boot-starter-undertow </dependency>
