Interface ConfigurableBeanFactory

All Superinterfaces:
BeanFactory, HierarchicalBeanFactory, SingletonBeanRegistry
All Known Subinterfaces:
ConfigurableListableBeanFactory
All Known Implementing Classes:
AbstractAutowireCapableBeanFactory, AbstractBeanFactory, DefaultListableBeanFactory
public interface ConfigurableBeanFactory extends HierarchicalBeanFactory, SingletonBeanRegistry
Configuration interface to be implemented by most bean factories. Provides facilities to configure a bean factory, in addition to the bean factory client methods in the BeanFactory interface.

This bean factory interface is not meant to be used in normal application code: Stick to BeanFactory or ListableBeanFactory for typical needs. This extended interface is just meant to allow for framework-internal plug'n'play and for special access to bean factory configuration methods.

    • setParentBeanFactory

      void setParentBeanFactory(BeanFactory parentBeanFactory) throws IllegalStateException
      Set the parent of this bean factory.

      Note that the parent cannot be changed: It should only be set outside a constructor if it isn't available at the time of factory instantiation.

      Parameters:
      parentBeanFactory - the parent BeanFactory
      Throws:
      IllegalStateException - if this factory is already associated with a parent BeanFactory
      See Also:

    • setBeanClassLoader

      void setBeanClassLoader(@Nullable ClassLoader beanClassLoader)
      Set the class loader to use for loading bean classes. Default is the thread context class loader.

      Note that this class loader will only apply to bean definitions that do not carry a resolved bean class yet. This is the case as of Spring 2.0 by default: Bean definitions only carry bean class names, to be resolved once the factory processes the bean definition.

      Parameters:
      beanClassLoader - the class loader to use, or null to suggest the default class loader

    • getBeanClassLoader

      @Nullable ClassLoader getBeanClassLoader()
      Return this factory's class loader for loading bean classes (only null if even the system ClassLoader isn't accessible).
      See Also:

    • setTempClassLoader

      void setTempClassLoader(@Nullable ClassLoader tempClassLoader)
      Specify a temporary ClassLoader to use for type matching purposes. Default is none, simply using the standard bean ClassLoader.

      A temporary ClassLoader is usually just specified if load-time weaving is involved, to make sure that actual bean classes are loaded as lazily as possible. The temporary loader is then removed once the BeanFactory completes its bootstrap phase.

      Since:
      2.5

    • getTempClassLoader

      @Nullable ClassLoader getTempClassLoader()
      Return the temporary ClassLoader to use for type matching purposes, if any.
      Since:
      2.5

    • setCacheBeanMetadata

      void setCacheBeanMetadata(boolean cacheBeanMetadata)
      Set whether to cache bean metadata such as given bean definitions (in merged fashion) and resolved bean classes. Default is on.

      Turn this flag off to enable hot-refreshing of bean definition objects and in particular bean classes. If this flag is off, any creation of a bean instance will re-query the bean class loader for newly resolved classes.

    • isCacheBeanMetadata

      boolean isCacheBeanMetadata()
      Return whether to cache bean metadata such as given bean definitions (in merged fashion) and resolved bean classes.

    • setBeanExpressionResolver

      void setBeanExpressionResolver(@Nullable BeanExpressionResolver resolver)
      Specify the resolution strategy for expressions in bean definition values.

      There is no expression support active in a BeanFactory by default. An ApplicationContext will typically set a standard expression strategy here, supporting "#{...}" expressions in a Unified EL compatible style.

      Since:
      3.0

    • getBeanExpressionResolver

      @Nullable BeanExpressionResolver getBeanExpressionResolver()
      Return the resolution strategy for expressions in bean definition values.
      Since:
      3.0

    • setBootstrapExecutor

      void setBootstrapExecutor(@Nullable Executor executor)
      Set the Executor (possibly a TaskExecutor) for background bootstrapping.
      Since:
      6.2
      See Also:

    • getBootstrapExecutor

      @Nullable Executor getBootstrapExecutor()
      Return the Executor (possibly a TaskExecutor) for background bootstrapping, if any.
      Since:
      6.2

    • setConversionService

      void setConversionService(@Nullable ConversionService conversionService)
      Specify a ConversionService to use for converting property values, as an alternative to JavaBeans PropertyEditors.
      Since:
      3.0

    • getConversionService

      @Nullable ConversionService getConversionService()
      Return the associated ConversionService, if any.
      Since:
      3.0

    • addPropertyEditorRegistrar

      void addPropertyEditorRegistrar(PropertyEditorRegistrar registrar)
      Add a PropertyEditorRegistrar to be applied to all bean creation processes.

      Such a registrar creates new PropertyEditor instances and registers them on the given registry, fresh for each bean creation attempt. This avoids the need for synchronization on custom editors; hence, it is generally preferable to use this method instead of registerCustomEditor(java.lang.Class<?>, java.lang.Class<? extends java.beans.PropertyEditor>).

      Parameters:
      registrar - the PropertyEditorRegistrar to register

    • registerCustomEditor

      void registerCustomEditor(Class<?> requiredType, Class<? extends PropertyEditor> propertyEditorClass)
      Register the given custom property editor for all properties of the given type. To be invoked during factory configuration.

      Note that this method will register a shared custom editor instance; access to that instance will be synchronized for thread-safety. It is generally preferable to use addPropertyEditorRegistrar(org.springframework.beans.PropertyEditorRegistrar) instead of this method, to avoid for the need for synchronization on custom editors.

      Parameters:
      requiredType - type of the property
      propertyEditorClass - the PropertyEditor class to register

    • copyRegisteredEditorsTo

      void copyRegisteredEditorsTo(PropertyEditorRegistry registry)
      Initialize the given PropertyEditorRegistry with the custom editors that have been registered with this BeanFactory.
      Parameters:
      registry - the PropertyEditorRegistry to initialize

    • setTypeConverter

      void setTypeConverter(TypeConverter typeConverter)
      Set a custom type converter that this BeanFactory should use for converting bean property values, constructor argument values, etc.

      This will override the default PropertyEditor mechanism and hence make any custom editors or custom editor registrars irrelevant.

      Since:
      2.5
      See Also:

    • getTypeConverter

      TypeConverter getTypeConverter()
      Obtain a type converter as used by this BeanFactory. This may be a fresh instance for each call, since TypeConverters are usually not thread-safe.

      If the default PropertyEditor mechanism is active, the returned TypeConverter will be aware of all custom editors that have been registered.

      Since:
      2.5

    • addEmbeddedValueResolver

      void addEmbeddedValueResolver(StringValueResolver valueResolver)
      Add a String resolver for embedded values such as annotation attributes.

      Since:
      3.0

    • hasEmbeddedValueResolver

      boolean hasEmbeddedValueResolver()
      Determine whether an embedded value resolver has been registered with this bean factory, to be applied through resolveEmbeddedValue(String).
      Since:
      4.3

    • resolveEmbeddedValue

      @Nullable String resolveEmbeddedValue(String value)
      Resolve the given embedded value, for example, an annotation attribute.
      Parameters:
      value - the value to resolve
      Returns:
      the resolved value (may be the original value as-is)
      Since:
      3.0

    • addBeanPostProcessor

      void addBeanPostProcessor(BeanPostProcessor beanPostProcessor)
      Add a new BeanPostProcessor that will get applied to beans created by this factory. To be invoked during factory configuration.

      Note: Post-processors submitted here will be applied in the order of registration; any ordering semantics expressed through implementing the Ordered interface will be ignored. Note that autodetected post-processors (for example, as beans in an ApplicationContext) will always be applied after programmatically registered ones.

      Parameters:
      beanPostProcessor - the post-processor to register

    • getBeanPostProcessorCount

      int getBeanPostProcessorCount()
      Return the current number of registered BeanPostProcessors, if any.

      scope - the backing Scope implementation

    • getRegisteredScopeNames

      String[] getRegisteredScopeNames()
      Return the names of all currently registered scopes.

      This will only return the names of explicitly registered scopes. Built-in scopes such as "singleton" and "prototype" won't be exposed.

    • copyConfigurationFrom

      void copyConfigurationFrom(ConfigurableBeanFactory otherFactory)
      Copy all relevant configuration from the given other factory.

      Parameters:
      otherFactory - the other BeanFactory to copy from

    • registerAlias

      void registerAlias(String beanName, String alias) throws BeanDefinitionStoreException
      Given a bean name, create an alias. We typically use this method to support names that are illegal within XML ids (used for bean names).

      Typically invoked during factory configuration, but can also be used for runtime registration of aliases. Therefore, a factory implementation should synchronize alias access.

      Parameters:
      beanName - the canonical name of the target bean
      alias - the alias to be registered for the bean
      Throws:
      BeanDefinitionStoreException - if the alias is already in use

    • resolveAliases

      void resolveAliases(StringValueResolver valueResolver)
      Resolve all alias target names and aliases registered in this factory, applying the given StringValueResolver to them.

      The value resolver may for example resolve placeholders in target bean names and even in alias names.

      Parameters:
      valueResolver - the StringValueResolver to apply
      Since:
      2.5

    • getMergedBeanDefinition

      BeanDefinition getMergedBeanDefinition(String beanName) throws NoSuchBeanDefinitionException
