How can I access 'spring.application.name' when defined in bootstrap.properties?

I have the following spring-boot 1.4.2.RELEASE sample app

@SpringBootApplication
public class Application {

    @Value("${spring.application.name}")
    private String applicationName;

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

And I have the following configuration defined in bootstrap.properties:

spring.application.name=sample-app

When run it I get the following error: 

java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.application.name' in string value "${spring.application.name}"

Any hint on why it fails to inject 'spring.application.name'? Need to define it there to support other spring boot cloud.

The first answer is correct. The default properties file is application.properties or application.yml.

The bootstrap file is properly for Spring Cloud.

See http://projects.spring.io/spring-cloud/spring-cloud.html#_the_bootstrap_application_context

If you are using spring cloud, and the bootstrap file is not working, you need to enable the "cloud" Spring profile.

For example using:

./gradlew -Dspring.profiles.active=cloud bootrun

or

./mvnw spring-boot:run -Dspring.profiles.active=cloud

By default, if you don't specify any properties source, spring boot will lookup for your property in the file application.properties. Therefore, you should rename your property file to that default name or manually specify a properties source for your bootstrap.properties
