ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean

by

Case 1:

@SpringBootApplication annotation missing in your spring boot starter class.

Case 2:

For non-web applications, disable web application type in the properties file.

In application.properties:

spring.main.web-application-type=none

If you use application.yml then add:

  spring:
    main:
      web-application-type: none

For web applications, extends *SpringBootServletInitializer* in the main class.

@SpringBootApplication
public class YourAppliationName extends SpringBootServletInitializer{
    public static void main(String[] args) {
        SpringApplication.run(YourAppliationName.class, args);
    }
}

Case 3:

If you use spring-boot-starter-webflux then also add spring-boot-starter-web as dependency.
