====== Adding Customized Properties in Application.properties file ======

  - In application.properties files, add your own properties such as <code>mypropertis.version=dev</code> in the empty space. Here we use ''mypropertis'' as prefix, you can use whatever you want.
  - To read such value, create a class as a @Component<code>
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
import lombok.Getter;
import lombok.Setter;

@Getter
@Setter
@ConfigurationProperties("mypropertis")
@Component
public class MyProperties {
    private String version= "";
}
</code> Note that we have use lombok for the getter and setter.
  - Since we register our class as a @Component, we can do <code>@Autowired
    private MyProperties myProperties;</code> in our controllers / services
  -  To get the value, we can do <code>myProperties.getVersion()</code> The value woule be "dev" in this case.
