public abstract class AbstractAutowireCapableBeanFactory
extends AbstractBeanFactory
implements AutowireCapableBeanFactory

Abstract bean factory superclass that implements default bean creation, with the full capabilities specified by the RootBeanDefinition class. Implements the AutowireCapableBeanFactory interface in addition to AbstractBeanFactory's createBean(java.lang.Class<T>) method.

Provides bean creation (with constructor resolution), property population, wiring (including autowiring), and initialization. Handles runtime bean references, resolves managed collections, calls initialization methods, etc. Supports autowiring constructors, properties by name, and properties by type.

The main template method to be implemented by subclasses is AutowireCapableBeanFactory.resolveDependency(DependencyDescriptor, String, Set, TypeConverter), used for autowiring by type. In case of a factory which is capable of searching its bean definitions, matching beans will typically be implemented through such a search. For other factory styles, simplified matching algorithms can be implemented.

Note that this class does not assume or implement bean definition registry capabilities. See DefaultListableBeanFactory for an implementation of the ListableBeanFactory and BeanDefinitionRegistry interfaces, which represent the API and SPI view of such a factory, respectively.

Constructor Detail

AbstractAutowireCapableBeanFactory

public AbstractAutowireCapableBeanFactory()

Create a new AbstractAutowireCapableBeanFactory.

AbstractAutowireCapableBeanFactory

public AbstractAutowireCapableBeanFactory(BeanFactory parentBeanFactory)

Create a new AbstractAutowireCapableBeanFactory with the given parent.

Parameters:

parentBeanFactory - parent bean factory, or null if none

Method Detail

setInstantiationStrategy

public void setInstantiationStrategy(InstantiationStrategy instantiationStrategy)

Set the instantiation strategy to use for creating bean instances. Default is CglibSubclassingInstantiationStrategy.

See Also:

CglibSubclassingInstantiationStrategy

getInstantiationStrategy

protected InstantiationStrategy getInstantiationStrategy()

Return the instantiation strategy to use for creating bean instances.

setParameterNameDiscoverer

public void setParameterNameDiscoverer(ParameterNameDiscoverer parameterNameDiscoverer)

Set the ParameterNameDiscoverer to use for resolving method parameter names if needed (e.g. for constructor names).

The default is LocalVariableTableParameterNameDiscoverer.

getParameterNameDiscoverer

protected ParameterNameDiscoverer getParameterNameDiscoverer()

Return the ParameterNameDiscoverer to use for resolving method parameter names if needed.

setAllowCircularReferences

public void setAllowCircularReferences(boolean allowCircularReferences)

Set whether to allow circular references between beans - and automatically try to resolve them.

Note that circular reference resolution means that one of the involved beans will receive a reference to another bean that is not fully initialized yet. This can lead to subtle and not-so-subtle side effects on initialization; it does work fine for many scenarios, though.

Default is "true". Turn this off to throw an exception when encountering a circular reference, disallowing them completely.

NOTE: It is generally recommended to not rely on circular references between your beans. Refactor your application logic to have the two beans involved delegate to a third bean that encapsulates their common logic.

setAllowRawInjectionDespiteWrapping

public void setAllowRawInjectionDespiteWrapping(boolean allowRawInjectionDespiteWrapping)

Set whether to allow the raw injection of a bean instance into some other bean's property, despite the injected bean eventually getting wrapped (for example, through AOP auto-proxying).

This will only be used as a last resort in case of a circular reference that cannot be resolved otherwise: essentially, preferring a raw instance getting injected over a failure of the entire bean wiring process.

Default is "false", as of Spring 2.0. Turn this on to allow for non-wrapped raw beans injected into some of your references, which was Spring 1.2's (arguably unclean) default behavior.

NOTE: It is generally recommended to not rely on circular references between your beans, in particular with auto-proxying involved.

See Also:

setAllowCircularReferences(boolean)

ignoreDependencyType

public void ignoreDependencyType(java.lang.Class type)

Ignore the given dependency type for autowiring: for example, String. Default is none.

ignoreDependencyInterface

public void ignoreDependencyInterface(java.lang.Class ifc)

Ignore the given dependency interface for autowiring.

This will typically be used by application contexts to register dependencies that are resolved in other ways, like BeanFactory through BeanFactoryAware or ApplicationContext through ApplicationContextAware.

By default, only the BeanFactoryAware interface is ignored. For further types to ignore, invoke this method for each type.

See Also:

BeanFactoryAware, ApplicationContextAware

copyConfigurationFrom

public void copyConfigurationFrom(ConfigurableBeanFactory otherFactory)

Description copied from interface: ConfigurableBeanFactory

Copy all relevant configuration from the given other factory.

Should include all standard configuration settings as well as BeanPostProcessors, Scopes, and factory-specific internal settings. Should not include any metadata of actual bean definitions, such as BeanDefinition objects and bean name aliases.

Specified by:

copyConfigurationFrom in interface ConfigurableBeanFactory

Overrides:

copyConfigurationFrom in class AbstractBeanFactory

Parameters:

otherFactory - the other BeanFactory to copy from

createBean

public <T> T createBean(java.lang.Class<T> beanClass)
             throws BeansException

Description copied from interface: AutowireCapableBeanFactory

Fully create a new bean instance of the given class.

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

Note: This is intended for creating a fresh instance, populating annotated fields and methods as well as applying all standard bean initialiation callbacks. It does not imply traditional by-name or by-type autowiring of properties; use AutowireCapableBeanFactory.createBean(Class, int, boolean) for that purposes.

Specified by:

createBean in interface AutowireCapableBeanFactory

Parameters:

beanClass - the class of the bean to create

Returns:

the new bean instance

Throws:

BeansException - if instantiation or wiring failed

autowireBean

public void autowireBean(java.lang.Object existingBean)

Description copied from interface: AutowireCapableBeanFactory

Populate the given bean instance through applying after-instantiation callbacks and bean property post-processing (e.g. for annotation-driven injection).

Note: This is essentially intended for (re-)populating annotated fields and methods, either for new instances or for deserialized instances. It does not imply traditional by-name or by-type autowiring of properties; use AutowireCapableBeanFactory.autowireBeanProperties(java.lang.Object, int, boolean) for that purposes.

Specified by:

autowireBean in interface AutowireCapableBeanFactory

Parameters:

existingBean - the existing bean instance

configureBean

public java.lang.Object configureBean(java.lang.Object existingBean,
                             java.lang.String beanName)
                               throws BeansException

Description copied from interface: AutowireCapableBeanFactory

Configure the given raw bean: autowiring bean properties, applying bean property values, applying factory callbacks such as setBeanName and setBeanFactory, and also applying all bean post processors (including ones which might wrap the given raw bean).

This is effectively a superset of what AutowireCapableBeanFactory.initializeBean(java.lang.Object, java.lang.String) provides, fully applying the configuration specified by the corresponding bean definition. Note: This method requires a bean definition for the given name!

Specified by:

configureBean in interface AutowireCapableBeanFactory

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 definition with the given name

BeansException - if the initialization failed

                            throws BeansException

Description copied from interface: AutowireCapableBeanFactory

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. This is effectively a superset of what AutowireCapableBeanFactory.autowire(java.lang.Class, int, boolean) provides, adding AutowireCapableBeanFactory.initializeBean(java.lang.Object, java.lang.String) behavior.

Specified by:

createBean in interface AutowireCapableBeanFactory

Parameters:

beanClass - the class of the bean to create

autowireMode - by name or type, using the constants in this interface

                             throws BeansException

Description copied from interface: AutowireCapableBeanFactory

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.

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

Does not apply standard BeanPostProcessors callbacks or perform any further initialization of the bean.

However, InstantiationAwareBeanPostProcessor callbacks are applied, if applicable to the configuration of the instance.

Specified by:

applyBeanPropertyValues in interface AutowireCapableBeanFactory

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 definition with the given name

BeansException - if applying the property values failed

Specified by:

createBean in class AbstractBeanFactory

Parameters:

beanName - the name of the bean

mbd - the merged bean definition for the bean

args - arguments to use if creating a prototype using explicit arguments to a static factory method. This parameter must be null except in this case.

predictBeanType

protected java.lang.Class predictBeanType(java.lang.String beanName,
                              RootBeanDefinition mbd,
                              java.lang.Class... typesToMatch)

Description copied from class: AbstractBeanFactory

Predict the eventual bean type (of the processed bean instance) for the specified bean. Called by AbstractBeanFactory.getType(java.lang.String) and AbstractBeanFactory.isTypeMatch(java.lang.String, java.lang.Class<?>). Does not need to handle FactoryBeans specifically, since it is only supposed to operate on the raw bean type.

This implementation is simplistic in that it is not able to handle factory methods and InstantiationAwareBeanPostProcessors. It only predicts the bean type correctly for a standard bean. To be overridden in subclasses, applying more sophisticated type detection.

Overrides:

predictBeanType in class AbstractBeanFactory

Parameters:

beanName - the name of the bean

mbd - the merged bean definition to determine the type for

typesToMatch - the types to match in case of internal type matching purposes (also signals that the returned Class will never be exposed to application code)

Returns:

the type of the bean, or null if not predictable

getTypeForFactoryMethod

protected java.lang.Class getTypeForFactoryMethod(java.lang.String beanName,
                                      RootBeanDefinition mbd,
                                      java.lang.Class[] typesToMatch)

Determine the bean type for the given bean definition which is based on a factory method. Only called if there is no singleton instance registered for the target bean already.

This implementation determines the type matching createBean(java.lang.Class<T>)'s different creation strategies. As far as possible, we'll perform static type checking to avoid creation of the target bean.

Parameters:

beanName - the name of the bean (for error handling purposes)

mbd - the merged bean definition for the bean

typesToMatch - the types to match in case of internal type matching purposes (also signals that the returned Class will never be exposed to application code)

Returns:

the type for the bean if determinable, or null else

See Also:

createBean(java.lang.Class<T>)

getTypeForFactoryBean

protected java.lang.Class<?> getTypeForFactoryBean(java.lang.String beanName,
                                       RootBeanDefinition mbd)

This implementation attempts to query the FactoryBean's generic parameter metadata if present to determine the object type. If not present, i.e. the FactoryBean is declared as a raw type, checks the FactoryBean's getObjectType method on a plain instance of the FactoryBean, without bean properties applied yet. If this doesn't return a type yet, a full creation of the FactoryBean is used as fallback (through delegation to the superclass's implementation).

The shortcut check for a FactoryBean is only applied in case of a singleton FactoryBean. If the FactoryBean instance itself is not kept as singleton, it will be fully created to check the type of its exposed object.

Overrides:

getTypeForFactoryBean in class AbstractBeanFactory

Parameters:

beanName - the name of the bean

mbd - the merged bean definition for the bean

Returns:

the type for the bean if determinable, or null else

See Also:

FactoryBean.getObjectType(), AbstractBeanFactory.getBean(String)

getEarlyBeanReference

                                     java.lang.Object bean)

Obtain a reference for early access to the specified bean, typically for the purpose of resolving a circular reference.

Parameters:

Returns:

the object to expose as bean reference

                              java.lang.Object[] explicitArgs)

"autowire constructor" (with constructor arguments by type) behavior. Also applied if explicit constructor argument values are specified, matching all remaining arguments with beans from the bean factory.

This corresponds to constructor injection: In this mode, a Spring bean factory is able to host components that expect constructor-based dependency resolution.

Parameters:

                  MutablePropertyValues pvs)

Fill in any missing property values with references to other beans in this factory if autowire is set to "byName".

Parameters:

beanName - the name of the bean we're wiring up. Useful for debugging messages; not used functionally.

mbd - bean definition to update through autowiring

bw - BeanWrapper from which we can obtain information about the bean

pvs - the PropertyValues to register wired objects with

                  MutablePropertyValues pvs)

Abstract method defining "autowire by type" (bean properties by type) behavior.

This is like PicoContainer default, in which there must be exactly one bean of the property type in the bean factory. This makes bean factories simple to configure for small namespaces, but doesn't work as well as standard Spring behavior for bigger applications.

Parameters:

beanName - the name of the bean to autowire by type

mbd - the merged bean definition to update through autowiring

bw - BeanWrapper from which we can obtain information about the bean

pvs - the PropertyValues to register wired objects with

Return an array of non-simple bean properties that are unsatisfied. These are probably unsatisfied references to other beans in the factory. Does not include simple properties like primitives or Strings.

Parameters:

mbd - the merged bean definition the bean was created with

bw - the BeanWrapper the bean was created with

Returns:

an array of bean property names
