Class IntegrationObjectSupport

java.lang.Object
org.springframework.integration.context.IntegrationObjectSupport
All Implemented Interfaces:
Aware, BeanFactoryAware, BeanNameAware, InitializingBean, ApplicationContextAware, ExpressionCapable, NamedComponent
Direct Known Subclasses:
AbstractConnectionFactory, AbstractEndpoint, AbstractHandleMessageAdvice, AbstractMailReceiver, AbstractMessageChannel, AbstractRequestHandlerAdvice, AbstractTransformer, CodecMessageConverter, DefaultHeaderChannelRegistry, ExpressionEvaluatingTransactionSynchronizationProcessor, HeaderEnricher, HeaderFilter, MessageHandlerSupport

public abstract class IntegrationObjectSupport extends Object implements BeanNameAware, NamedComponent, ApplicationContextAware, BeanFactoryAware, InitializingBean, ExpressionCapable
A base class that provides convenient access to the bean factory as well as 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.

      Specify the DestinationResolver strategy to use. The default is a BeanFactoryChannelResolver.
      Parameters:
      channelResolver - The channel resolver.
    • getExpression

      public Expression getExpression()
      Description copied from interface: ExpressionCapable
      Return the primary SpEL expression if this component is expression-based.

      Returns:
      the expression as a String.
    • setPrimaryExpression

      public final void setPrimaryExpression(Expression expression)
      For expression-based components, set the primary expression.
      Parameters:
      expression - the expression.
      Since:
      4.3

      public final void afterPropertiesSet()
      Specified by:
      afterPropertiesSet in interface InitializingBean
    • onInit

      protected void onInit()
      Subclasses may implement this for initialization logic.
    • isInitialized

      protected boolean isInitialized()
      Return the status of this component if it has been initialized already.
