public class ResourceAdapterFactoryBean extends Object implements FactoryBean<ResourceAdapter>, InitializingBean, DisposableBean
FactoryBean that bootstraps
the specified JCA 1.7 ResourceAdapter,
starting it with a local BootstrapContext
and exposing it for bean references. It will also stop the ResourceAdapter
on context shutdown. This corresponds to 'non-managed' bootstrap in a
local environment, according to the JCA 1.7 specification.
This is essentially an adapter for bean-style bootstrapping of a JCA ResourceAdapter, allowing the BootstrapContext or its elements (such as the JCA WorkManager) to be specified through bean properties.

| Modifier and Type | Method and Description |
|---|---|
void |
afterPropertiesSet()
Builds the BootstrapContext and starts the ResourceAdapter with it.
|
void |
destroy()
Stops the ResourceAdapter.
|
ResourceAdapter |
getObject()
Return an instance (possibly shared or independent) of the object
managed by this factory.
|
Class<? extends ResourceAdapter> |
getObjectType()
Return the type of object that this FactoryBean creates,
or
null if not known in advance. |
boolean |
isSingleton()
Is the object managed by this factory a singleton? That is,
will
FactoryBean.getObject() always return the same object
(a reference that can be cached)? |
void |
setBootstrapContext(BootstrapContext bootstrapContext)
Specify the JCA BootstrapContext to use for starting the ResourceAdapter.
|
void |
setResourceAdapter(ResourceAdapter resourceAdapter)
Specify the target JCA ResourceAdapter, passed in as configured instance
which hasn't been started yet.
|
void |
setResourceAdapterClass(Class<? extends ResourceAdapter> resourceAdapterClass)
Specify the target JCA ResourceAdapter as class, to be instantiated
with its default configuration.
|
void |
setWorkManager(WorkManager workManager)
Specify the JCA WorkManager to use for bootstrapping the ResourceAdapter.
|
void |
setXaTerminator(XATerminator xaTerminator)
Specify the JCA XATerminator to use for bootstrapping the ResourceAdapter.
|
public void setResourceAdapterClass(Class<? extends ResourceAdapter> resourceAdapterClass)
Alternatively, specify a pre-configured ResourceAdapter instance through the "resourceAdapter" property.
public void setResourceAdapter(ResourceAdapter resourceAdapter)
public void setBootstrapContext(BootstrapContext bootstrapContext)
Alternatively, you can specify the individual parts (such as the JCA WorkManager) as individual references.
public void setWorkManager(WorkManager workManager)
public void setXaTerminator(XATerminator xaTerminator)

FactoryBeanAs with a BeanFactory, this allows support for both the
Singleton and Prototype design pattern.
If this FactoryBean is not fully initialized yet at the time of
the call (for example because it is involved in a circular reference),
throw a corresponding FactoryBeanNotInitializedException.
As of Spring 2.0, FactoryBeans are allowed to return null
objects. The factory will consider this as normal value to be used; it
will not throw a FactoryBeanNotInitializedException in this case anymore.
FactoryBean implementations are encouraged to throw
FactoryBeanNotInitializedException themselves now, as appropriate.

FactoryBeannull if not known in advance.
This allows one to check for specific types of beans without instantiating objects, for example on autowiring.
In the case of implementations that are creating a singleton object, this method should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.
This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.
NOTE: Autowiring will simply ignore FactoryBeans that return
null here. Therefore, it is highly recommended to implement
this method properly, using the current state of the FactoryBean.

FactoryBeanFactoryBean.getObject() always return the same object
(a reference that can be cached)?
NOTE: If a FactoryBean indicates to hold a singleton object,
the object returned from getObject() might get cached
by the owning BeanFactory. Hence, do not return true
unless the FactoryBean always exposes the same reference.
The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.
NOTE: This method returning false does not
necessarily indicate that returned objects are independent instances.
An implementation of the extended SmartFactoryBean interface
may explicitly indicate independent instances through its
SmartFactoryBean.isPrototype() method. Plain FactoryBean
implementations which do not implement this extended interface are
simply assumed to always return independent instances if the
isSingleton() implementation returns false.
The default implementation returns true, since a
FactoryBean typically manages a singleton instance.
