Class AbstractMethodInvokingAdapter

java.lang.Object
  org.springframework.integration.util.AbstractMethodInvokingAdapter

All Implemented Interfaces:

org.springframework.beans.factory.InitializingBean, org.springframework.core.Ordered, MethodInvoker

Direct Known Subclasses:

AbstractMessageHandlerAdapter, AnnotationMethodTransformerAdapter, PayloadTransformerAdapter

public abstract class AbstractMethodInvokingAdapter
extends java.lang.Object
implements MethodInvoker, org.springframework.beans.factory.InitializingBean, org.springframework.core.Ordered

An base class for adapters that invoke a specified method and target object. Either a Method reference or a 'methodName' may be provided, but both are not necessary. In fact, while preference is given to a Method reference if available, an Exception will be thrown if a non-matching 'methodName' has also been provided. Therefore, to avoid such ambiguity, it is recommended to provide just one or the other.
