Class AbstractApplicationContextFactory

java.lang.Object

org.springframework.batch.core.configuration.support.AbstractApplicationContextFactory

All Implemented Interfaces:

ApplicationContextFactory, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware

Direct Known Subclasses:

GenericApplicationContextFactory

public abstract class AbstractApplicationContextFactory
extends Object
implements ApplicationContextFactory, org.springframework.context.ApplicationContextAware

ApplicationContextFactory implementation that takes a parent context and a path to the context to create. When createApplicationContext method is called, the child ApplicationContext will be returned. The child context is not re-created every time it is requested, it is lazily initialized and cached. Clients should ensure that it is closed when it is no longer needed. If a path is not set, the parent will always be returned.

Constructor Detail

AbstractApplicationContextFactory

public AbstractApplicationContextFactory(Object resource)

Create a factory instance with the resource specified. The resource is a Spring configuration file or java package containing configuration files.

Method Detail

setCopyConfiguration

public void setCopyConfiguration(boolean copyConfiguration)

Flag to indicate that configuration such as bean post processors and custom editors should be copied from the parent context. Defaults to true.

Parameters:

copyConfiguration - the flag value to set

isCopyConfiguration

protected final boolean isCopyConfiguration()

Protected access for subclasses to the flag determining whether configuration should be copied from parent context.

Returns:

the flag value

setBeanFactoryPostProcessorClasses

public void setBeanFactoryPostProcessorClasses(Class<? extends org.springframework.beans.factory.config.BeanFactoryPostProcessor>[] beanFactoryPostProcessorClasses)

Determines which bean factory post processors (like property placeholders) should be copied from the parent context. Defaults to PropertyPlaceholderConfigurer and CustomEditorConfigurer.

Parameters:

beanFactoryPostProcessorClasses - array of post processor types to be copied

setBeanPostProcessorExcludeClasses

public void setBeanPostProcessorExcludeClasses(Class<?>[] beanPostProcessorExcludeClasses)

Determines by exclusion which bean post processors should be copied from the parent context. Defaults to BeanFactoryAware (so any post processors that have a reference to the parent bean factory are not copied into the child). Note that these classes do not themselves have to be BeanPostProcessor implementations or sub-interfaces.

Parameters:

beanPostProcessorExcludeClasses - the classes to set

getBeanFactoryPostProcessorClasses

protected final Collection<Class<? extends org.springframework.beans.factory.config.BeanFactoryPostProcessor>> getBeanFactoryPostProcessorClasses()

Protected access to the list of bean factory post processor classes that should be copied over to the context from the parent.

Returns:

the classes for post processors that were nominated for copying

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Setter for the parent application context.

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException

See Also:

ApplicationContextAware.setApplicationContext(org.springframework.context.ApplicationContext)

createApplicationContext

public org.springframework.context.ConfigurableApplicationContext createApplicationContext()

Creates an ApplicationContext from the provided path.

Specified by:

createApplicationContext in interface ApplicationContextFactory

See Also:

ApplicationContextFactory.createApplicationContext()

createApplicationContext

protected abstract org.springframework.context.ConfigurableApplicationContext createApplicationContext(org.springframework.context.ConfigurableApplicationContext parent,
                                                                                  Object resource)

prepareContext

protected void prepareContext(org.springframework.context.ConfigurableApplicationContext parent,
                  org.springframework.context.ConfigurableApplicationContext context)

Extension point for special subclasses that want to do more complex things with the context prior to refresh. The default implementation does nothing.

Parameters:

parent - the parent for the new application context

context - the new application context before it is refreshed, but after bean factory is initialized

See Also:

setBeanFactoryPostProcessorClasses(Class[])

prepareBeanFactory

protected void prepareBeanFactory(org.springframework.beans.factory.config.ConfigurableListableBeanFactory parent,
                      org.springframework.beans.factory.config.ConfigurableListableBeanFactory beanFactory)

Extension point for special subclasses that want to do more complex things with the bean factory prior to refresh. The default implementation copies all configuration from the parent according to the flag set.

Parameters:

parent - the parent bean factory for the new context (will never be null)

beanFactory - the new bean factory before bean definitions are loaded

setCopyConfiguration(boolean), DefaultListableBeanFactory.copyConfigurationFrom(ConfigurableBeanFactory)
