Class DefaultListableBeanFactory

Constructor Detail

• DefaultListableBeanFactory

  public DefaultListableBeanFactory()

  Create a new DefaultListableBeanFactory.

• DefaultListableBeanFactory

  public DefaultListableBeanFactory​(BeanFactory parentBeanFactory)

  Create a new DefaultListableBeanFactory with the given parent.

  Parameters:

  parentBeanFactory - the parent BeanFactory

Method Detail

• setSerializationId

  public void setSerializationId​(String serializationId)

  Specify an id for serialization purposes, allowing this BeanFactory to be deserialized from this id back into the BeanFactory object, if needed.

• getSerializationId

  public String getSerializationId()

  Return an id for serialization purposes, if specified, allowing this BeanFactory to be deserialized from this id back into the BeanFactory object, if needed.

  Since:

  4.1.2

• setAllowBeanDefinitionOverriding

  public void setAllowBeanDefinitionOverriding​(boolean allowBeanDefinitionOverriding)

  Set whether it should be allowed to override bean definitions by registering a different definition with the same name, automatically replacing the former. If not, an exception will be thrown. This also applies to overriding aliases.

  Default is "true".

  See Also:

  registerBeanDefinition(java.lang.String, org.springframework.beans.factory.config.BeanDefinition)

• isAllowBeanDefinitionOverriding

  public boolean isAllowBeanDefinitionOverriding()

  Return whether it should be allowed to override bean definitions by registering a different definition with the same name, automatically replacing the former.

  Since:

  4.1.2

• setAllowEagerClassLoading

  public void setAllowEagerClassLoading​(boolean allowEagerClassLoading)

  Set whether the factory is allowed to eagerly load bean classes even for bean definitions that are marked as "lazy-init".

  Default is "true". Turn this flag off to suppress class loading for lazy-init beans unless such a bean is explicitly requested. In particular, by-type lookups will then simply ignore bean definitions without resolved class name, instead of loading the bean classes on demand just to perform a type check.

  See Also:

  AbstractBeanDefinition.setLazyInit(boolean)

• isAllowEagerClassLoading

  public boolean isAllowEagerClassLoading()

  Return whether the factory is allowed to eagerly load bean classes even for bean definitions that are marked as "lazy-init".

  Since:

  4.1.2

• setDependencyComparator

  public void setDependencyComparator​(Comparator<Object> dependencyComparator)

  Set a Comparator for dependency Lists and arrays.

  Since:

  4.0

  See Also:

  OrderComparator, AnnotationAwareOrderComparator

• getDependencyComparator

  public Comparator<Object> getDependencyComparator()

  Return the dependency comparator for this BeanFactory (may be null.

  Since:

  4.0

• setAutowireCandidateResolver

  public void setAutowireCandidateResolver​(AutowireCandidateResolver autowireCandidateResolver)

  Set a custom autowire candidate resolver for this BeanFactory to use when deciding whether a bean definition should be considered as a candidate for autowiring.

• getAutowireCandidateResolver

  public AutowireCandidateResolver getAutowireCandidateResolver()

  Return the autowire candidate resolver for this BeanFactory (never null).

• 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 AbstractAutowireCapableBeanFactory

  Parameters:

  otherFactory - the other BeanFactory to copy from

• getBean

  public <T> T getBean​(Class<T> requiredType)
                throws BeansException

  Description copied from interface: BeanFactory
  Return the bean instance that uniquely matches the given object type, if any.

  This method goes into ListableBeanFactory by-type lookup territory but may also be translated into a conventional by-name lookup based on the name of the given type. For more extensive retrieval operations across sets of beans, use ListableBeanFactory and/or BeanFactoryUtils.

  Specified by:

  getBean in interface BeanFactory

  Parameters:

  requiredType - type the bean must match; can be an interface or superclass

  Returns:

  an instance of the single bean matching the required type

  Throws:

  NoSuchBeanDefinitionException - if no bean of the given type was found

  NoUniqueBeanDefinitionException - if more than one bean of the given type was found

  BeansException - if the bean could not be created

  See Also:

  ListableBeanFactory

• getBean

  public <T> T getBean​(Class<T> requiredType,
                       Object... args)
                throws BeansException

  Description copied from interface: BeanFactory
  Return an instance, which may be shared or independent, of the specified bean.

  Allows for specifying explicit constructor arguments / factory method arguments, overriding the specified default arguments (if any) in the bean definition.

  This method goes into ListableBeanFactory by-type lookup territory but may also be translated into a conventional by-name lookup based on the name of the given type. For more extensive retrieval operations across sets of beans, use ListableBeanFactory and/or BeanFactoryUtils.

  Specified by:

  getBean in interface BeanFactory

  Parameters:

  requiredType - type the bean must match; can be an interface or superclass

  args - arguments to use when creating a bean instance using explicit arguments (only applied when creating a new instance as opposed to retrieving an existing one)

  Returns:

  an instance of the bean

  Throws:

  NoSuchBeanDefinitionException - if there is no such bean definition

  BeanDefinitionStoreException - if arguments have been given but the affected bean isn't a prototype

  BeansException - if the bean could not be created

• containsBeanDefinition

  public boolean containsBeanDefinition​(String beanName)

  Description copied from class: AbstractBeanFactory
  Check if this bean factory contains a bean definition with the given name. Does not consider any hierarchy this factory may participate in. Invoked by containsBean when no cached singleton instance is found.

  Depending on the nature of the concrete bean factory implementation, this operation might be expensive (for example, because of directory lookups in external registries). However, for listable bean factories, this usually just amounts to a local hash lookup: The operation is therefore part of the public interface there. The same implementation can serve for both this template method and the public interface method in that case.

  Specified by:

  containsBeanDefinition in interface BeanDefinitionRegistry

  Specified by:

  containsBeanDefinition in interface ListableBeanFactory

  Specified by:

  containsBeanDefinition in class AbstractBeanFactory

  Parameters:

  beanName - the name of the bean to look for

  Returns:

  if this bean factory contains a bean definition with the given name

  See Also:

  AbstractBeanFactory.containsBean(java.lang.String), ListableBeanFactory.containsBeanDefinition(java.lang.String)

• getBeanDefinitionCount

  public int getBeanDefinitionCount()

  Description copied from interface: ListableBeanFactory
  Return the number of beans defined in the factory.

  Does not consider any hierarchy this factory may participate in, and ignores any singleton beans that have been registered by other means than bean definitions.

  Specified by:

  getBeanDefinitionCount in interface BeanDefinitionRegistry

  Specified by:

  getBeanDefinitionCount in interface ListableBeanFactory

  Returns:

  the number of beans defined in the factory

• getBeanDefinitionNames

  public String[] getBeanDefinitionNames()

  Description copied from interface: ListableBeanFactory
  Return the names of all beans defined in this factory.

  Does not consider any hierarchy this factory may participate in, and ignores any singleton beans that have been registered by other means than bean definitions.

  Specified by:

  getBeanDefinitionNames in interface BeanDefinitionRegistry

  Specified by:

  getBeanDefinitionNames in interface ListableBeanFactory

  Returns:

  the names of all beans defined in this factory, or an empty array if none defined

• getBeanNamesForType

  public String[] getBeanNamesForType​(ResolvableType type)

  Description copied from interface: ListableBeanFactory
  Return the names of beans matching the given type (including subclasses), judging from either bean definitions or the value of getObjectType in the case of FactoryBeans.

  NOTE: This method introspects top-level beans only. It does not check nested beans which might match the specified type as well.

  Does consider objects created by FactoryBeans, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type.

  Does not consider any hierarchy this factory may participate in. Use BeanFactoryUtils' beanNamesForTypeIncludingAncestors to include beans in ancestor factories too.

  Note: Does not ignore singleton beans that have been registered by other means than bean definitions.

  This version of getBeanNamesForType matches all kinds of beans, be it singletons, prototypes, or FactoryBeans. In most implementations, the result will be the same as for getBeanNamesForType(type, true, true).

  Bean names returned by this method should always return bean names in the order of definition in the backend configuration, as far as possible.

  Specified by:

  getBeanNamesForType in interface ListableBeanFactory

  Parameters:

  type - the class or interface to match, or null for all bean names

  Returns:

  the names of beans (or objects created by FactoryBeans) matching the given object type (including subclasses), or an empty array if none

• getBeanNamesForType

  public String[] getBeanNamesForType​(Class<?> type,
                                      boolean includeNonSingletons,

  Description copied from interface: ListableBeanFactory
  Return the names of beans matching the given type (including subclasses), judging from either bean definitions or the value of getObjectType in the case of FactoryBeans.

  NOTE: This method introspects top-level beans only. It does not check nested beans which might match the specified type as well.

  Does consider objects created by FactoryBeans if the "allowEagerInit" flag is set, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type. If "allowEagerInit" is not set, only raw FactoryBeans will be checked (which doesn't require initialization of each FactoryBean).

  Does not consider any hierarchy this factory may participate in. Use BeanFactoryUtils' beanNamesForTypeIncludingAncestors to include beans in ancestor factories too.

  Note: Does not ignore singleton beans that have been registered by other means than bean definitions.

  Bean names returned by this method should always return bean names in the order of definition in the backend configuration, as far as possible.

  Specified by:

  getBeanNamesForType in interface ListableBeanFactory

  Parameters:

  type - the class or interface to match, or null for all bean names

  includeNonSingletons - whether to include prototype or scoped beans too or just singletons (also applies to FactoryBeans)

  allowEagerInit - whether to initialize lazy-init singletons and objects created by FactoryBeans (or by factory methods with a "factory-bean" reference) for the type check. Note that FactoryBeans need to be eagerly initialized to determine their type: So be aware that passing in "true" for this flag will initialize FactoryBeans and "factory-bean" references.

  Returns:

  the names of beans (or objects created by FactoryBeans) matching the given object type (including subclasses), or an empty array if none

  Description copied from interface: ListableBeanFactory
  Return the bean instances that match the given object type (including subclasses), judging from either bean definitions or the value of getObjectType in the case of FactoryBeans.

  NOTE: This method introspects top-level beans only. It does not check nested beans which might match the specified type as well.

  Does consider objects created by FactoryBeans, which means that FactoryBeans will get initialized. If the object created by the FactoryBean doesn't match, the raw FactoryBean itself will be matched against the type.

• registerResolvableDependency

  public void registerResolvableDependency​(Class<?> dependencyType,
                                           Object autowiredValue)

  Description copied from interface: ConfigurableListableBeanFactory
  Register a special dependency type with corresponding autowired value.

  This is intended for factory/context references that are supposed to be autowirable but are not defined as beans in the factory: e.g. a dependency of type ApplicationContext resolved to the ApplicationContext instance that the bean is living in.

  Note: There are no such default types registered in a plain BeanFactory, not even for the BeanFactory interface itself.

  Specified by:

  registerResolvableDependency in interface ConfigurableListableBeanFactory

  Parameters:

  dependencyType - the dependency type to register. This will typically be a base interface such as BeanFactory, with extensions of it resolved as well if declared as an autowiring dependency (e.g. ListableBeanFactory), as long as the given value actually implements the extended interface.

  autowiredValue - the corresponding autowired value. This may also be an implementation of the ObjectFactory interface, which allows for lazy resolution of the actual target value.

• isAutowireCandidate

• getBeanDefinition

  public BeanDefinition getBeanDefinition​(String beanName)
                                   throws NoSuchBeanDefinitionException

  Description copied from class: AbstractBeanFactory
  Return the bean definition for the given bean name. Subclasses should normally implement caching, as this method is invoked by this class every time bean definition metadata is needed.

  Depending on the nature of the concrete bean factory implementation, this operation might be expensive (for example, because of directory lookups in external registries). However, for listable bean factories, this usually just amounts to a local hash lookup: The operation is therefore part of the public interface there. The same implementation can serve for both this template method and the public interface method in that case.

  getBeanDefinition in interface BeanDefinitionRegistry

  Specified by:

  getBeanDefinition in interface ConfigurableListableBeanFactory

  Specified by:

  Parameters:

  beanName - the name of the bean to find a definition for

  Returns:

  the BeanDefinition for this prototype name (never null)

  Throws:

  NoSuchBeanDefinitionException - if the bean definition cannot be resolved

• getBeanNamesIterator

  public Iterator<String> getBeanNamesIterator()

  Description copied from interface: ConfigurableListableBeanFactory
  Return a unified view over all bean names managed by this factory.

  Includes bean definition names as well as names of manually registered singleton instances, with bean definition names consistently coming first, analogous to how type/annotation specific retrieval of bean names works.

  Specified by:

  getBeanNamesIterator in interface ConfigurableListableBeanFactory

  Returns:

  the composite iterator for the bean names view

• clearMetadataCache

  public void clearMetadataCache()

  Description copied from class: AbstractBeanFactory
  Clear the merged bean definition cache, removing entries for beans which are not considered eligible for full metadata caching yet.

  Typically triggered after changes to the original bean definitions, e.g. after applying a BeanFactoryPostProcessor. Note that metadata for beans which have already been created at this point will be kept around.

• registerSingleton

  public void registerSingleton​(String beanName,
                                Object singletonObject)
                         throws IllegalStateException

  Description copied from interface: SingletonBeanRegistry
  Register the given existing object as singleton in the bean registry, under the given bean name.

  The given instance is supposed to be fully initialized; the registry will not perform any initialization callbacks (in particular, it won't call InitializingBean's afterPropertiesSet method). The given instance will not receive any destruction callbacks (like DisposableBean's destroy method) either.

  When running within a full BeanFactory: Register a bean definition instead of an existing instance if your bean is supposed to receive initialization and/or destruction callbacks.

  Typically invoked during registry configuration, but can also be used for runtime registration of singletons. As a consequence, a registry implementation should synchronize singleton access; it will have to do this anyway if it supports a BeanFactory's lazy initialization of singletons.

  Specified by:

  registerSingleton in interface SingletonBeanRegistry

  Overrides:

  registerSingleton in class DefaultSingletonBeanRegistry

  Parameters:

  beanName - the name of the bean

  singletonObject - the existing singleton object

  Throws:

  IllegalStateException

• destroySingleton

  public void destroySingleton​(String beanName)

  Description copied from class: DefaultSingletonBeanRegistry
  Destroy the given bean. Delegates to destroyBean if a corresponding disposable bean instance is found.

  Overrides:

  DefaultSingletonBeanRegistry.destroyBean(java.lang.String, org.springframework.beans.factory.DisposableBean)

• destroySingletons

  public void destroySingletons()

  Description copied from interface: ConfigurableBeanFactory
  Destroy all singleton beans in this factory, including inner beans that have been registered as disposable. To be called on shutdown of a factory.

  Any exception that arises during destruction should be caught and logged instead of propagated to the caller of this method.

  Description copied from interface: AutowireCapableBeanFactory
  Resolve the bean instance that uniquely matches the given object type, if any, including its bean name.

  This is effectively a variant of BeanFactory.getBean(Class) which preserves the bean name of the matching instance.

  Specified by:

  resolveNamedBean in interface AutowireCapableBeanFactory

  Parameters:

  requiredType - type the bean must match; can be an interface or superclass

  Returns:

  the bean name plus bean instance

  whether the given bean qualifies as primary

• getPriority

  protected Integer getPriority​(Object beanInstance)

  Return the priority assigned for the given bean instance by the javax.annotation.Priority annotation.

  The default implementation delegates to the specified dependency comparator, checking its method if it is an extension of Spring's common OrderComparator - typically, an AnnotationAwareOrderComparator. If no such comparator is present, this implementation returns null.

  Parameters:

  beanInstance - the bean instance to check (can be null)

  Returns:

  the priority assigned to that bean or null if none is set
