public class MethodInvokingJobDetailFactoryBean extends ArgumentConvertingMethodInvoker implements FactoryBean<JobDetail>, BeanNameAware, BeanClassLoaderAware, BeanFactoryAware, InitializingBean
FactoryBeanthat exposes a
JobDetailobject which delegates job execution to a specified (static or non-static) method. Avoids the need for implementing a one-line Quartz Job that just invokes an existing service method on a Spring-managed target bean.
Inherits common configuration properties from the
base class, such as
"targetMethod", adding support for lookup of the target
bean by name through the
(as alternative to specifying a "targetObject" directly, allowing for
non-singleton target objects).
Supports both concurrently running jobs and non-currently running jobs through the "concurrent" property. Jobs created by this MethodInvokingJobDetailFactoryBean are by default volatile and durable (according to Quartz terminology).
NOTE: JobDetails created via this FactoryBean are not serializable and thus not suitable for persistent job stores. You need to implement your own Quartz Job as a thin wrapper for each case where you want a persistent job to delegate to a specific service method.
Compatible with Quartz 2.1.4 and higher, as of Spring 4.1.

public void setName(String name)
Default is the bean name of this FactoryBean.
public void setGroup(String group)
Default is the default group of the Scheduler.

The default setting is to run jobs concurrently.
public void setTargetBeanName(String targetBeanName)
This is an alternative to specifying
allowing for non-singleton beans to be invoked. Note that specified
"targetClass" values will
override the corresponding effect of this "targetBeanName" setting
(i.e. statically pre-define the bean type or even the bean object).
public void setBeanName(String beanName)
Invoked after population of normal bean properties but before an
init callback such as
or a custom init-method.
beanName- the name of the bean in the factory. Note that this name is the actual bean name used in the factory, which may differ from the originally specified name: in particular for inner bean names, the actual bean name might have been made unique through appending "#..." suffixes. Use the
BeanFactoryUtils.originalBeanName(String)method to extract the original bean name (without suffix), if desired.
public void setBeanClassLoader(ClassLoader classLoader)
class loaderto a bean instance.
Invoked after the population of normal bean properties but
before an initialization callback such as

Invoked after the population of normal bean properties

public void afterPropertiesSet() throws ClassNotFoundException, NoSuchMethodException
This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

The default implementation is empty. Can be overridden in subclasses.

As of Spring 2.0, FactoryBeans are allowed to return
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.
public Class<? extends JobDetail> getObjectType()
nullif 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.

public boolean isSingleton()
FactoryBean.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
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.isPrototype() method. Plain
implementations which do not implement this extended interface are
simply assumed to always return independent instances if the

true, since a
FactoryBean typically manages a singleton instance.
