application.properties not showing values set by @ConfigurationProperties

There's a tutorial in the book that I'm reading about application.properties having the capability of using intellisense to find properties of a class when @ConfigurationProperties is set. However, it's not working when I try it. I'm not sure what I'm missing.

Main class:

package com.hecklers.sburrestdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationPropertiesScan;

@SpringBootApplication
@ConfigurationPropertiesScan
public class SburRestDemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(SburRestDemoApplication.class, args);
    }

}

Greeting class: package com.hecklers.sburrestdemo;

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = "greeting")
class Greeting {
    private String name;
    private String coffee;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getCoffee() {
        return coffee;
    }

    public void setCoffee(String coffee) {
        this.coffee = coffee;
    }
}
