I am getting the above message when I try to run my Spring Boot application. 

Does anyone know how I can re-run the application with 'debug' enabled? 

I am running the application in Intellij (version 2016.1.2)

My runner class looks like the following,

```
@Slf4j
@EnableIntegration
@EnableLoaderApplication
@SpringBootApplication
public class LoaderApplicaton {

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

```

In response to Darren's answer below, I amended my properties.yml file as follows and that produced the auto-configuration report,

```
debug: true
spring:
  application:
    name: xxxMyLoaderApp
  cloud:
    config:
      uri: http://my-host.address.com:8761/config

```

Answer: 
Set `debug = true` or `debug: true` in your properties/yml. It can also be passed as an argument `--debug`.

There are further details available in the Spring Boot documentation on what the debug flag does.

<https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-logging-console-output>
Set `logging.level.org.springframework.boot.autoconfigure` property to `DEBUG` in your application's YAML/settings file. This would be enough.
