Can't read values from property file

• Framework version: 1.1
• Implementations: Spring Boot

Scenario

Once app is starting I want to have possibility to read values from properties file ie. application.yml. I have defined app as below:

@SpringBootApplication
@ComponentScan({"foo.bar"})
public class Application extends SpringBootServletInitializer {
    @Value("${foo.clientId}")
    private String clientId;
}

Once app is up and running clientId should be populated with values provided in the file. I have configured handler as provided in Readme file:

public class StreamLambdaHandler implements RequestStreamHandler {

    private static SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;

    static {
        try {
            handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(Application.class);
        } catch (ContainerInitializationException e) {
            // if we fail here. We re-throw the exception to force another cold start
            e.printStackTrace();
            throw new RuntimeException("Could not initialize Spring Boot application", e);
        }
    }

    @Override
    public void handleRequest(InputStream inputStream, OutputStream outputStream, Context context)
            throws IOException {
        handler.proxyStream(inputStream, outputStream, context);

        // just in case it wasn't closed by the mapper
        outputStream.close();
    }
}

Expected behavior

Filed clientId populated with value from properties file

Actual behavior

Exception during lambda start process: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'application': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'foo.clientId' in value "${foo.clientId}"

Steps to reproduce

Create app as above, create properties file, put placeholders, deploy on AWS and run.

Resolving this as a duplicate of #133. Support for both assembly and gradle will go out in version 1.3 shortly

Ok, I found a workaround. The problem is mainly with application.yml file. With application.properties it works, but you have to provide path to the file with PropertySource annotation as follow:

@SpringBootApplication
@ComponentScan({"foo.bar"})
@PropertySource("classpath:application.properties")
public class Application extends SpringBootServletInitializer {
...
}

However it doesn’t work perfectly as I tried turn off a banner (spring.main.banner-mode=off) but it still appears in the CloudWatch logs.
