Class JobRegistryBeanPostProcessor

java.lang.Object
  org.springframework.batch.core.configuration.support.JobRegistryBeanPostProcessor

All Implemented Interfaces:

org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.InitializingBean

public class JobRegistryBeanPostProcessor
extends java.lang.Object
implements org.springframework.beans.factory.config.BeanPostProcessor, org.springframework.beans.factory.BeanFactoryAware, org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.DisposableBean

A BeanPostProcessor that registers Job beans with a JobRegistry. Include a bean of this type along with your job configuration, and use the same JobRegistry as a JobLocator when you need to locate a Job to launch.

Constructor Detail

JobRegistryBeanPostProcessor

public JobRegistryBeanPostProcessor()

Method Detail

setGroupName

public void setGroupName(java.lang.String groupName)

The group name for jobs registered by this component. Optional (defaults to null, which means that jobs are registered with their bean names). Useful where there is a hierarchy of application contexts all contributing to the same JobRegistry: child contexts can then define an instance with a unique group name to avoid clashes between job names.

Parameters:

groupName - the groupName to set

setJobRegistry

public void setJobRegistry(JobRegistry jobRegistry)

Injection setter for JobRegistry.

Parameters:

jobRegistry - the jobConfigurationRegistry to set

setBeanFactory

public void setBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)
                    throws org.springframework.beans.BeansException

Specified by:

setBeanFactory in interface org.springframework.beans.factory.BeanFactoryAware

Throws:

org.springframework.beans.BeansException

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.lang.Exception

Make sure the registry is set before use.

Specified by:

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Throws:

java.lang.Exception

See Also:

InitializingBean.afterPropertiesSet()

destroy

public void destroy()
             throws java.lang.Exception

De-register all the Job instances that were regsistered by this post processor.

Specified by:

destroy in interface org.springframework.beans.factory.DisposableBean

Throws:

java.lang.Exception

See Also:

DisposableBean.destroy()

postProcessAfterInitialization

public java.lang.Object postProcessAfterInitialization(java.lang.Object bean,
                                                       java.lang.String beanName)
                                                throws org.springframework.beans.BeansException

If the bean is an instance of Job then register it.

Specified by:

postProcessAfterInitialization in interface org.springframework.beans.factory.config.BeanPostProcessor

Throws:

org.springframework.beans.FatalBeanException - if there is a DuplicateJobException.

org.springframework.beans.BeansException

See Also:

BeanPostProcessor.postProcessAfterInitialization(java.lang.Object, java.lang.String)

getGroupName

protected java.lang.String getGroupName(org.springframework.beans.factory.config.BeanDefinition beanDefinition,
                                        Job job)

Determine a group name for the job to be registered. Default implementation just returns the groupName configured. Provides an extension point for specialised subclasses.

Parameters:

beanDefinition - the bean definition for the job

job - the job

Returns:

a group name for the job (or null if not needed)

postProcessBeforeInitialization

public java.lang.Object postProcessBeforeInitialization(java.lang.Object bean,
                                                        java.lang.String beanName)
                                                 throws org.springframework.beans.BeansException

Do nothing.

Specified by:

postProcessBeforeInitialization in interface org.springframework.beans.factory.config.BeanPostProcessor

Throws:

org.springframework.beans.BeansException
