[spring] ApplicationContextException: Unable to start ServletWebServerApplicationContext due to missing ServletWebServerFactory bean

You probably use this in your project:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-webflux</artifactId>
</dependency>

in which case you'll have to also add:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

and the magic happens :)

PS: that's because Spring will use by default web-MVC instead of web-flux when both are available
