Spring Boot without the web server

if you want to run Spring Boot 1.x without a servlet container, but with one on the classpath (e.g. for tests), use the following, as described in the spring boot documentation:

@Configuration
@EnableAutoConfiguration
public class MyClass {
    public static void main(String[] args) throws JAXBException {
         SpringApplication app = new SpringApplication(MyClass.class);
         app.setWebEnvironment(false); //<<<<<<<<<
         ConfigurableApplicationContext ctx = app.run(args);
    }
}

also, I just stumbled across this property:

spring.main.web-environment=false
