Class BeanInvokingActionFactory

java.lang.Object
  org.springframework.webflow.action.BeanInvokingActionFactory

public class BeanInvokingActionFactory
extends java.lang.Object

A helper factory for Action instances that invoke methods on beans managed in a Spring bean factory.

This factory encapsulates the logic required to take an arbitrary java.lang.Object from a Spring bean factory and adapt a method on it to the Action interface. If the bean you want to use is not managed in a Spring bean factory, consider subclassing AbstractBeanInvokingAction and using it directly.

createBeanInvokingAction

public Action createBeanInvokingAction(java.lang.String beanId,
                                       org.springframework.beans.factory.BeanFactory beanFactory,
                                       org.springframework.binding.method.MethodSignature methodSignature,
                                       ActionResultExposer resultExposer,
                                       org.springframework.binding.convert.ConversionService conversionService,
                                       AttributeMap attributes)

Factory method that creates a bean invoking action, an adapter that adapts a method on an abitrary Object to the Action interface. This method is an atomic operation that returns a fully initialized Action. It encapsulates the selection of the action implementation as well as the action assembly.

Parameters:

beanId - the id of the bean to be adapted to an Action instance

beanFactory - the bean factory where the bean is managed

methodSignature - the method to invoke on the bean when the action is executed (required)

resultExposer - the specification for what to do with the method return value (optional)

conversionService - the conversion service to be used to convert method parameters (optional)

attributes - attributes that may be used to affect the bean invoking action's construction

Returns:

the fully configured bean invoking action instance
