Interface AutowireCapableBeanFactory

All Superinterfaces:: BeanFactory

All Known Subinterfaces:: ConfigurableListableBeanFactory

All Known Implementing Classes:: AbstractAutowireCapableBeanFactory, DefaultListableBeanFactory, XmlBeanFactory

public interface AutowireCapableBeanFactory
extends BeanFactory
extends BeanFactory

Extension of the BeanFactory interface to be implemented by bean factories that are capable of autowiring, provided that they want to expose this functionality for existing bean instances.

This subinterface of BeanFactory is not meant to be used in normal application code: stick to BeanFactory or ListableBeanFactory for typical use cases.

Integration code for other frameworks can leverage this interface to wire and populate existing bean instances that Spring does not control the lifecycle of. This is particularly useful for WebWork Actions and Tapestry Page objects, for example.

Note that this interface is not implemented by ApplicationContext facades, as it is hardly ever used by application code. That said, it is available from an application context too, accessible through ApplicationContext's ApplicationContext.getAutowireCapableBeanFactory() method.

You may also implement the BeanFactoryAware interface, which exposes the internal BeanFactory even when running in an ApplicationContext, to get access to an AutowireCapableBeanFactory: simply cast the passed-in BeanFactory to AutowireCapableBeanFactory.

Method Detail

createBean

Object createBean(Class beanClass,
                  int autowireMode,
                  boolean dependencyCheck)
                  throws BeansException

Fully create a new bean instance of the given class with the specified autowire strategy. All constants defined in this interface are supported here.

Performs full initialization of the bean, including all applicable BeanPostProcessors.

Parameters:: beanClass - the class of the bean to create; autowireMode - by name or type, using the constants in this interface; dependencyCheck - whether to perform a dependency check for objects (not applicable to autowiring a constructor, thus ignored there)
Returns:: the new bean instance
Throws:: BeansException - if instantiation or wiring failed
See Also:: AUTOWIRE_NO, AUTOWIRE_BY_NAME, AUTOWIRE_BY_TYPE, AUTOWIRE_CONSTRUCTOR, AUTOWIRE_AUTODETECT

autowire

Object autowire(Class beanClass,
                int autowireMode,
                boolean dependencyCheck)
                throws BeansException

Instantiate a new bean instance of the given class with the specified autowire strategy. All constants defined in this interface are supported here.

Does not apply any BeanPostProcessors or perform any further initialization of the bean. This interface offers distinct, fine-grained operations for those purposes, for example initializeBean(java.lang.Object, java.lang.String).

Parameters:: beanClass - the class of the bean to instantiate; autowireMode - by name or type, using the constants in this interface; dependencyCheck - whether to perform a dependency check for object references in the bean instance (not applicable to autowiring a constructor, thus ignored there)
Returns:: the new bean instance
Throws:: BeansException - if instantiation or wiring failed
See Also:: AUTOWIRE_NO, AUTOWIRE_BY_NAME, AUTOWIRE_BY_TYPE, AUTOWIRE_CONSTRUCTOR, AUTOWIRE_AUTODETECT, initializeBean(java.lang.Object, java.lang.String), applyBeanPostProcessorsBeforeInitialization(java.lang.Object, java.lang.String), applyBeanPostProcessorsAfterInitialization(java.lang.Object, java.lang.String)

autowireBeanProperties

void autowireBeanProperties(Object existingBean,
                            int autowireMode,
                            boolean dependencyCheck)
                            throws BeansException

Autowire the bean properties of the given bean instance by name or type.

Parameters:: existingBean - the existing bean instance; autowireMode - by name or type, using the constants in this interface; dependencyCheck - whether to perform a dependency check for object references in the bean instance
Throws:: BeansException - if wiring failed
See Also:: AUTOWIRE_BY_NAME, AUTOWIRE_BY_TYPE

applyBeanPropertyValues

void applyBeanPropertyValues(Object existingBean,
                             String beanName)
                             throws BeansException

Apply the property values of the bean definition with the given name to the given bean instance. The bean definition can either define a fully self-contained bean, reusing its property values, or just property values meant to be used for existing bean instances.

Note: This method does not autowire bean properties; it just applies explicitly defined property values. Use the autowireBeanProperties(java.lang.Object, int, boolean) method to autowire an existing bean instance.

Parameters:: existingBean - the existing bean instance; beanName - the name of the bean definition in the bean factory (a bean definition of that name has to be available)
Throws:: NoSuchBeanDefinitionException - if there is no bean with the given name; BeansException - if applying the property values failed
See Also:: autowireBeanProperties(java.lang.Object, int, boolean)

configureBean

Object configureBean(Object existingBean,
                     String beanName)
                     throws BeansException

Configure the given bean instance: autowiring bean properties, applying bean property values, applying factory callbacks such as setBeanName and setBeanFactory, and also applying all bean post processors.

This is effectively a superset of what initializeBean provides, fully applying the configuration specified by the corresponding bean definition.

Parameters:: existingBean - the existing bean instance; beanName - the name of the bean, to be passed to it if necessary (a bean definition of that name has to be available)
Returns:: the bean instance to use, either the original or a wrapped one
Throws:: NoSuchBeanDefinitionException - if there is no bean with the given name; BeansException - if the initialization failed
See Also:: initializeBean(java.lang.Object, java.lang.String)

initializeBean

Object initializeBean(Object existingBean,
                      String beanName)
                      throws BeansException

Initialize the given bean instance, applying factory callbacks such as setBeanName and setBeanFactory, also applying all bean post processors.

Note that no bean definition of the given name has to exist in the bean factory. The passed-in bean name will simply be used for callbacks but not checked against the registered bean definitions.

Parameters:: existingBean - the existing bean instance; beanName - the name of the bean, to be passed to it if necessary (only passed to BeanPostProcessors)
Returns:: the bean instance to use, either the original or a wrapped one
Throws:: BeansException - if the initialization failed

applyBeanPostProcessorsBeforeInitialization

Object applyBeanPostProcessorsBeforeInitialization(Object existingBean,
                                                   String beanName)
                                                   throws BeansException

Apply BeanPostProcessors to the given existing bean instance, invoking their postProcessBeforeInitialization methods. The returned bean instance may be a wrapper around the original.

Parameters:: existingBean - the new bean instance; beanName - the name of the bean
Returns:: the bean instance to use, either the original or a wrapped one
Throws:: BeansException - if any post-processing failed
See Also:: BeanPostProcessor.postProcessBeforeInitialization(java.lang.Object, java.lang.String)

applyBeanPostProcessorsAfterInitialization

Object applyBeanPostProcessorsAfterInitialization(Object existingBean,
                                                  String beanName)
                                                  throws BeansException

Apply BeanPostProcessors to the given existing bean instance, invoking their postProcessAfterInitialization methods. The returned bean instance may be a wrapper around the original.

Parameters:: existingBean - the new bean instance; beanName - the name of the bean
Returns:: the bean instance to use, either the original or a wrapped one
Throws:: BeansException - if any post-processing failed
