Class QuartzJobBean

  extended by org.springframework.scheduling.quartz.QuartzJobBean
All Implemented Interfaces:
Direct Known Subclasses:

public abstract class QuartzJobBean
extends Object
implements org.quartz.Job

Simple implementation of the Quartz Job interface, applying the passed-in JobDataMap and also the SchedulerContext as bean property values. This is appropriate because a new Job instance will be created for each execution. JobDataMap entries will override SchedulerContext entries with the same keys.

For example, let's assume that the JobDataMap contains a key "myParam" with value "5": The Job implementation can then expose a bean property "myParam" of type int to receive such a value, i.e. a method "setMyParam(int)". This will also work for complex types like business objects etc.

Note: The QuartzJobBean class itself only implements the standard Quartz Job interface. Let your subclass explicitly implement the Quartz StatefulJob interface to mark your concrete job bean as stateful.

This version of QuartzJobBean requires Quartz 1.5 or higher, due to the support for trigger-specific job data.

Note that as of Spring 2.0 and Quartz 1.5, the preferred way to apply dependency injection to Job instances is via a JobFactory: that is, to specify SpringBeanJobFactory as Quartz JobFactory (typically via SchedulerFactoryBean.setJobFactory(org.quartz.spi.JobFactory) SchedulerFactoryBean's "jobFactory" property}). This allows to implement dependency-injected Quartz Jobs without a dependency on Spring base classes.

Method Detail


public final void execute(org.quartz.JobExecutionContext context)
                   throws org.quartz.JobExecutionException
This implementation applies the passed-in job data map as bean property values, and delegates to executeInternal afterwards.

Specified by:
execute in interface org.quartz.Job
See Also:


protected abstract void executeInternal(org.quartz.JobExecutionContext context)
                                 throws org.quartz.JobExecutionException
Execute the actual job. The job data map will already have been applied as bean property values by execute. The contract is exactly the same as for the standard Quartz execute method.
