What difference does @EnableConfigurationproperties make if a bean is already annotated with @ConfigurationProperties?

Question

The Spring Boot documentation says that to use the @ConfigurationProperties annotation

You also need to list the properties classes to regis

Answer 1

If we look at the code below:

@Configuration @EnableConfigurationProperties @ConfigurationProperties(prefix="ar1") public class ar1Settings { }

• @Configuration tells Spring to treat this as a configuration class and register it as a Bean

• @EnableConfigurationProperties tells Spring to treat this class as a consumer of application.yml/properties values

• @ConfigurationProperties tells Spring what section this class represents.

My understanding is that if you don't need to specify the section of the property file, then @ConfigurationProperties can be omitted.
