- Run Spring Boot app as Java app instead of on server, because the server is already embedded inside the app.

- Inject values from application.properties file with *__@Value__* 

[[FunRestController](https://github.com/cpulover-practice/spring-boot/blob/master/src/main/java/com/cpulover/springboot/rest/FunRestController.java)]
