LiveReload: The Spring Boot DevTools module includes an embedded server called LiveReload.

 It allows the application to automictically trigger a browser refresh whenever we make changes in the resources. It is also known as auto-refresh. 

Note: We can disable the LiveReload by setting the property spring.
