  org.springframework.core.io.DefaultResourceLoader
      org.springframework.context.support.AbstractApplicationContext
          org.springframework.context.support.AbstractRefreshableApplicationContext

All Implemented Interfaces:

org.springframework.beans.factory.BeanFactory, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.HierarchicalBeanFactory, org.springframework.beans.factory.ListableBeanFactory, org.springframework.context.ApplicationContext, org.springframework.context.ApplicationEventPublisher, org.springframework.context.ConfigurableApplicationContext, org.springframework.context.Lifecycle, org.springframework.context.MessageSource, org.springframework.core.io.ResourceLoader, org.springframework.core.io.support.ResourcePatternResolver

Direct Known Subclasses:

AnnotationApplicationContext

public abstract class AbstractAnnotationApplicationContext
extends org.springframework.context.support.AbstractRefreshableApplicationContext

Convenient superclass for ApplicationContext implementations that read bean definitions from class bytecode.

This class registers each bean definition with the DefaultListableBeanFactory superclass, and relies on the latter's implementation of the BeanFactory interface. It supports singletons, prototypes, and references to both kinds of bean.

Method Detail

registerDefaultPostProcessors

protected void registerDefaultPostProcessors()

Register the default post processors used for parsing Spring classes.

loadBeanDefinitions

protected void loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory beanFactory)
                            throws java.io.IOException,
                                   org.springframework.beans.BeansException

Specified by:

loadBeanDefinitions in class org.springframework.context.support.AbstractRefreshableApplicationContext

Throws:

java.io.IOException

org.springframework.beans.BeansException

createAnnotationBeanDefinitionReader

protected AbstractClassScanningBeanDefinitionReader createAnnotationBeanDefinitionReader(org.springframework.beans.factory.support.DefaultListableBeanFactory beanFactory)

loadBeanDefinitions

protected void loadBeanDefinitions(AbstractClassScanningBeanDefinitionReader reader)
                            throws org.springframework.beans.BeansException,
                                   java.io.IOException

Load bean definitions with the given AbstractAnnotationBeanDefinitionReader.

The lifecycle of the bean factory is handled by the refreshBeanFactory method; therefore this method is just supposed to load and/or register bean definitions.

Delegates to a ResourcePatternResolver for resolving location patterns into Resource instances.

Throws:

org.springframework.beans.BeansException - in case of bean registration errors

java.io.IOException - if the required class definition isn't found

AbstractRefreshableApplicationContext.refreshBeanFactory(), getConfigLocations(), AbstractApplicationContext.getResources(java.lang.String), AbstractApplicationContext.getResourcePatternResolver()

loadBeanDefinitions

protected int loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory beanFactory,
                                  java.lang.Class... configClasses)

Load bean definitions from configuration classes.

Since Class objects cannot be easily translated into a byte array or InputStream, they have be parsed separately.

Parameters:

configClasses -

containsConfiguration

protected boolean containsConfiguration(java.lang.Class<?> clazz)

Discriminator between configuration and non-configuration classes.

Parameters:

clazz -

Returns:

getConfigResources

protected org.springframework.core.io.Resource[] getConfigResources()

Return an array of Resource objects, referring to the class bean definition files that this context should be built with.

Default implementation returns null. Subclasses can override this to provide pre-built Resource objects rather than location Strings.

Returns:

an array of Resource objects, or null if none

See Also:

getConfigLocations()

getConfigLocations

protected java.lang.String[] getConfigLocations()

Return an array of resource locations, referring to the class bean definition files that this context should be built with. Can also include location patterns, which will get resolved via a ResourcePatternResolver.

Default implementation returns null. Subclasses can override this to provide a set of resource locations to load bean definitions from.

Returns:

an array of resource locations, or null if none

See Also:

AbstractApplicationContext.getResources(java.lang.String), AbstractApplicationContext.getResourcePatternResolver()

getConfigClasses

protected java.lang.Class[] getConfigClasses()

Return an array of Class objects which act as definition files for a spring context.

Default implementation returns null. Subclasses can override this to provide pre-built Class objects rather than location Strings or Resources. This class should be mainly use when runtime generating classes are used (runtime compiled Groovy scripts or ASM 'synthetic' classes).

Returns:

an array of Class objects, or null if none
