You have to mention in the main class the class you want to use @ConfigurationProperties annotation like below.

@EnableConfigurationProperties(AppProperties.class)

The Property Configuration class with @ConfigurationProperties will be like this

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


@ConfigurationProperties(prefix = "app")
public class AppProperties {
    String name;
    String id;
}

The Main class will be like this

import com.auth2.demo.config.AppProperties;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;

@SpringBootApplication
@EnableConfigurationProperties(AppProperties.class)
public class DemoApplication {

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

}
