Class Configurations

java.lang.Object

org.springframework.boot.context.annotation.Configurations

Direct Known Subclasses:

AutoConfigurations, UserConfigurations

public abstract class Configurations
extends Object

A set of @Configuration classes that can be registered in ApplicationContext. Classes can be returned from one or more Configurations instances by using getClasses(Configurations[]). The resulting array follows the ordering rules usually applied by the ApplicationContext and/or custom ImportSelector implementations.

This class is primarily intended for use with tests that need to specify configuration classes but can't use SpringRunner.

Implementations of this class should be annotated with @Order or implement Ordered.

Since:

2.0.0
