public abstract class IntegrationObjectSupport extends Object implements BeanNameAware, NamedComponent, ApplicationContextAware, BeanFactoryAware, InitializingBean, ExpressionCapable
TaskScheduler and ConversionService instances.
This is intended to be used as a base class for internal framework components whereas code built upon the integration framework should not require tight coupling with the context but rather rely on standard dependency injection.
