Class MethodInvokingJobDetailFactoryBean

All Implemented Interfaces:
Aware, BeanClassLoaderAware, BeanFactoryAware, BeanNameAware, FactoryBean<JobDetail>, InitializingBean

public class MethodInvokingJobDetailFactoryBean extends ArgumentConvertingMethodInvoker implements FactoryBean<JobDetail>, BeanNameAware, BeanClassLoaderAware, BeanFactoryAware, InitializingBean
FactoryBean that exposes a JobDetail object 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 MethodInvoker base class, such as "targetObject" and "targetMethod", adding support for lookup of the target bean by name through the "targetBeanName" property (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.

    • setName

      public void setName(String name)
      Set the name of the job.

      Default is the bean name of this FactoryBean.

    • setGroup

      public void setGroup(String group)
      Set the group of the job.

      Default is the default group of the Scheduler.

      See Also:
    • 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 @PersistJobDataAfterExecution and @DisallowConcurrentExecution markers. More information on stateful versus stateless jobs can be found here.

      The default setting is to run jobs concurrently.

    • setTargetBeanName

      public void setTargetBeanName(String targetBeanName)
      Set the name of the target bean in the Spring BeanFactory.

      This is an alternative to specifying "targetObject", allowing for non-singleton beans to be invoked. Note that specified "targetObject" and "targetClass" values will override the corresponding effect of this "targetBeanName" setting (i.e. statically pre-define the bean type or even the bean object).

    • setBeanName

      public void setBeanName(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 such as InitializingBean.afterPropertiesSet() or a custom init-method.

      Specified by:
      setBeanName in interface BeanNameAware
      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.
    • setBeanClassLoader

      public void setBeanClassLoader(ClassLoader classLoader)
      Description copied from interface: BeanClassLoaderAware
      Callback that supplies the bean class loader to a bean instance.

      Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean's InitializingBean.afterPropertiesSet() method or a custom init-method.

      Specified by:
      setBeanClassLoader in interface BeanClassLoaderAware
      classLoader - the owning class loader
    • setBeanFactory

      public void setBeanFactory(BeanFactory beanFactory)
      Description copied from interface: BeanFactoryAware
      Callback that supplies the owning factory to a bean instance.

      Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean.afterPropertiesSet() or a custom init-method.

      Specified by:
      setBeanFactory in interface BeanFactoryAware
      beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

    • resolveClassName

      protected Class<?> resolveClassName(String className) throws ClassNotFoundException
      Description copied from class: MethodInvoker
      Resolve the given class name into a Class.

      The default implementations uses ClassUtils.forName, using the thread context class loader.

      resolveClassName in class MethodInvoker
      className - the class name to resolve
      the resolved Class
      ClassNotFoundException - if the class name was invalid
    • afterPropertiesSet

      public void afterPropertiesSet() throws ClassNotFoundException, NoSuchMethodException
      Description copied from interface: InitializingBean
      Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

      This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

      Specified by:
      afterPropertiesSet in interface InitializingBean
    • postProcessJobDetail

      protected void postProcessJobDetail(JobDetail jobDetail)
      Callback for post-processing the JobDetail to be exposed by this FactoryBean.

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

      jobDetail - the JobDetail prepared by this FactoryBean
    • getTargetClass

      public Class<?> getTargetClass()
      Overridden to support the "targetBeanName" feature.
      getTargetClass in class MethodInvoker
    • getTargetObject

      public Object getTargetObject()
      Overridden to support the "targetBeanName" feature.
      getTargetObject in class MethodInvoker
    • getObject

      @Nullable public JobDetail 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.

      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.

      Specified by:
      getObject in interface FactoryBean<JobDetail>
      an instance of the bean (can be null)
      See Also:
    • getObjectType

      public Class<? extends JobDetail> getObjectType()
      Description copied from interface: FactoryBean
      Return the type of object that this FactoryBean creates, or null 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.

      Specified by:
      getObjectType in interface FactoryBean<JobDetail>
      the type of object that this FactoryBean creates, or null if not known at the time of the call
      See Also:
    • isSingleton

      public boolean isSingleton()
      Description copied from interface: FactoryBean
      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)?

      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.

      Specified by:
      isSingleton in interface FactoryBean<JobDetail>
      whether the exposed object is a singleton
