How to force Spring Boot to use Tomcat server in integration tests?

Question

I use default Tomcat embedded container. However, in some of my tests I use Wiremock (using Jetty underneath). This makes my integration tests run against Jetty server, not Tomcat.

Is there any way to force Spring Boot to stick with Tomcat ?

Answer 1

With Spring Boot 2.3 the above solution hasn't worked for me.

Perhaps I have special circumstances with not having a SpringBootApplication in the main classes. I have only a SpringBootApplication in the test classes.

Anyhow this has worked for me:

@SpringBootApplication(exclude = org.springframework.boot.autoconfigure.web.embedded.EmbeddedWebServerFactoryCustomizerAutoConfiguration.class)
public class TestApplication {
}
