Class SpringBeanLookup

java.lang.Object
  org.mule.object.AbstractObjectFactory
      org.mule.config.spring.util.SpringBeanLookup

All Implemented Interfaces:

Disposable, Initialisable, ObjectFactory, org.springframework.context.ApplicationContextAware

public class SpringBeanLookup
extends AbstractObjectFactory
implements org.springframework.context.ApplicationContextAware

This is an implementation of the ObjectFactory interface which simply delegates to the Spring ApplicationContext. Since the delegation happens each time a call to getOrCreate() is made, this will correctly handle Spring beans which are non-singletons (factory beans, etc.) Singleton usage: Non-singleton usage:

Method Detail

initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Overrides:

initialise in class AbstractObjectFactory

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

dispose

public void dispose()

Description copied from interface: Disposable

A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.

Specified by:

dispose in interface Disposable

Overrides:

dispose in class AbstractObjectFactory

getObjectClass

public Class getObjectClass()

Description copied from interface: ObjectFactory

Returns the class of the object to be instantiated without actually creating an instance. This may not be logical or even possible depending on the implementation.

Specified by:

getObjectClass in interface ObjectFactory

Overrides:

getObjectClass in class AbstractObjectFactory

getInstance

public Object getInstance()
                   throws Exception

Description copied from class: AbstractObjectFactory

Creates an initialized object instance based on the class and sets any properties.

Specified by:

getInstance in interface ObjectFactory

Overrides:

getInstance in class AbstractObjectFactory

Throws:

Exception

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException

getBean

public String getBean()

setBean

public void setBean(String bean)

isSingleton

public boolean isSingleton()

Description copied from interface: ObjectFactory

Returns true if the ObjectFactory implementation always returns the same object instance.

Specified by:

isSingleton in interface ObjectFactory

Overrides:

isSingleton in class AbstractObjectFactory

Returns:

isExternallyManagedLifecycle

public boolean isExternallyManagedLifecycle()

Description copied from interface: ObjectFactory

Returns true if Mule should not manage the life-cycle the object instance returned from the ObjectFactory. This is normally false except when an ObjectFactory implementation obtains instance from containers (e.g. Spring) that already manages the objects lifecycle. instance.

Specified by:

isExternallyManagedLifecycle in interface ObjectFactory

Overrides:

isExternallyManagedLifecycle in class AbstractObjectFactory

Returns:
