Third-party Configuration

As well as using @ConfigurationProperties to annotate a class, you can also use it on public @Bean methods. Doing so can be particularly useful when you want to bind properties to third-party components that are outside of your control.

To configure a bean from the Environment properties, add @ConfigurationProperties to its bean registration, as shown in the following example:

Java
Kotlin

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration(proxyBeanMethods = false)
public class ThirdPartyConfiguration {

	@Bean
	@ConfigurationProperties(prefix = "another")
	public AnotherComponent anotherComponent() {
		return new AnotherComponent();
	}

}

import org.springframework.boot.context.properties.ConfigurationProperties
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration

@Configuration(proxyBeanMethods = false)
class ThirdPartyConfiguration {

	@Bean
	@ConfigurationProperties(prefix = "another")
	fun anotherComponent(): AnotherComponent = AnotherComponent()

}

Any JavaBean property defined with the another prefix is mapped onto that AnotherComponent bean in manner similar to the preceding SomeProperties example.
