23.3 Customizing SpringApplication

If the SpringApplication defaults aren’t to your taste you can instead create a local instance and customize it. For example, to turn off the banner you would write:

public static void main(String[] args) {
    SpringApplication app = new SpringApplication(MySpringConfiguration.class);
    app.setBannerMode(Banner.Mode.OFF);
    app.run(args);
}

	Note
The constructor arguments passed to SpringApplication are configuration sources for spring beans. In most cases these will be references to @Configuration classes, but they could also be references to XML configuration or to packages that should be scanned.

It is also possible to configure the SpringApplication using an application.properties file. See [Chapter 24, _Externalized Configuration](http://docs.spring.io/spring-boot/docs/1.4.1.BUILD-SNAPSHOT/reference/htmlsingle/#boot-features-external-config)_ for details.

For a complete list of the configuration options, see the SpringApplication Javadoc.
