java.lang.Object
  org.springframework.util.MethodInvoker
      org.springframework.beans.support.ArgumentConvertingMethodInvoker
          org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean

All Implemented Interfaces:

BeanNameAware, FactoryBean, InitializingBean

public class MethodInvokingJobDetailFactoryBean

extends ArgumentConvertingMethodInvoker

implements FactoryBean, BeanNameAware, InitializingBean

FactoryBean that exposes a JobDetail object that delegates job execution to a specified (static or non-static) method. Avoids the need to implement a one-line Quartz Job that just invokes an existing business method.

Derived from MethodInvoker to share common properties and behavior with MethodInvokingFactoryBean.

Supports both concurrently running jobs and non-currently running ones through the "concurrent" property.

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 to delegate to an external method.

Constructor Detail

MethodInvokingJobDetailFactoryBean

public MethodInvokingJobDetailFactoryBean()

Method Detail

setName

public void setName(java.lang.String name)

Set the name of the job. Default is the bean name of this FactoryBean.

See Also:

JobDetail.setName(java.lang.String)

setGroup

public void setGroup(java.lang.String group)

Set the group of the job. Default is the default group of the Scheduler.

See Also:

JobDetail.setGroup(java.lang.String), Scheduler.DEFAULT_GROUP

setConcurrent

public void setConcurrent(boolean concurrent)

Specify whether or not multiple jobs should be run in a concurrent fashion. The behavior when one does not want concurrent jobs to be executed is realized through adding the StatefulJob interface. More information on stateful versus stateless jobs can be found here.

The default setting is to run jobs concurrently.

Parameters:

concurrent - whether one wants to execute multiple jobs created by this bean concurrently

setBeanName

public void setBeanName(java.lang.String beanName)

Description copied from interface: BeanNameAware

Set the name of the bean in the bean factory that created this bean.

Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method.

Specified by:

setBeanName in interface BeanNameAware

Parameters:

beanName - the name of the bean in the factory

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.lang.ClassNotFoundException,
                               java.lang.NoSuchMethodException

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

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.

Specified by:

afterPropertiesSet in interface InitializingBean

Throws:

java.lang.ClassNotFoundException

java.lang.NoSuchMethodException

getObject

public java.lang.Object getObject()

Description copied from interface: FactoryBean

Return an instance (possibly shared or independent) of the object managed by this factory. As with a BeanFactory, this allows support for both the Singleton and Prototype design pattern.

Specified by:

getObject in interface FactoryBean

Returns:

an instance of the bean (should never be null)

getObjectType

public java.lang.Class getObjectType()

Description copied from interface: FactoryBean

Return the type of object that this FactoryBean creates, or null if not known in advance. This allows to check for specific types of beans without instantiating objects, e.g. on autowiring.

For a singleton, this can simply return getObject().getClass(), or even null, as autowiring will always check the actual objects for singletons. For prototypes, returning a meaningful type here is highly advisable, as autowiring will simply ignore them else.

Specified by:

getObjectType in interface FactoryBean

Returns:

the type of object that this FactoryBean creates, or null

See Also:

ListableBeanFactory.getBeansOfType(java.lang.Class, boolean, boolean)

isSingleton

public boolean isSingleton()

Description copied from interface: FactoryBean

Is the bean managed by this factory a singleton or a prototype? That is, will getObject() always return the same object?

The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory.

Specified by:

isSingleton in interface FactoryBean

Returns:

if this bean is a singleton
