Getting exception Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean - spring

Question

I am getting the below exception.
Caused by: org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.
Below is the my build.gradle
buildscript {
ext {
springBootVersion = '1.4.0.RELEASE'
}
repositories {
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}

}
compile("org.springframework.boot:spring-boot-starter")
testCompile('org.springframework.boot:spring-boot-starter-test')
}
My application is a non-web application. I run it from command line and use following code.
#SpringBootApplication
public class MyApplication implements CommandLineRunner{
#Autowired
private Executor routeExecutor;
public static void main(String[] args) {
SpringApplication.run(MyApplication.class, args);
}
#Override
public void run(String... args) throws Exception {
System.out.println("Running Application from run method..");
this.routeExecutor.executeRoute();
}
}
I don't want tomcat. I have looked for this exception and it is a common one but I do not want to add "spring-boot-starter-web" dependency because it is a non-web application. Please help me out

Answer 1

Spring Boot has incorrectly guessed that you're trying to build a web application based on what you've got on the classpath. You can correct it by using SpringApplicationBuilder and setting web to false in your main method:
public static void main(String[] args) {
new SpringApplicationBuilder(MyApplication.class).web(false).run(args);
}
