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:

org.springframework.boot <artifactId>spring-boot-starter-web</artifactId> org.springframework.boot <artifactId>spring-boot-starter-tomcat</artifactId> org.springframework.boot <artifactId>spring-boot-starter-undertow</artifactId>
