How do you implement and use parameters from a Bean configuration file in a Spring application?

In Spring, to inject parameters from a configuration file into a Bean, the @Value annotation is usually used or parameters are bound through @ConfigurationProperties.

Example with @Value:

@Component
public class MyBean {
    @Value("${my.property.name}")
    private String propertyName;

    public void printProperty() {
        System.out.println(propertyName);
    }
}

A value is set in application.properties or application.yml:

my.property.name=Example value

When Spring starts, it injects the value from the configuration into the propertyName field.

Alternatively, a class with @ConfigurationProperties can be used to group parameters into a single object.
