  public DefaultListableBeanFactory​(@Nullable
                                    BeanFactory parentBeanFactory)

  Create a new DefaultListableBeanFactory with the given parent.

  参数:

  parentBeanFactory - the parent BeanFactory

方法详细资料

• setSerializationId

  public void setSerializationId​(@Nullable
                                 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

  @Nullable
  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.

  从以下版本开始:

  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".

  另请参阅:

  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.

  从以下版本开始:

  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.

  另请参阅:

  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".

                throws BeansException

  从接口复制的说明: 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.

  指定者:

                throws BeansException

  从接口复制的说明: 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.

  指定者:

  getBean 在接口中 BeanFactory

  参数:

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

  参数:

  requiredType - type the bean must match; can be a generic type declaration. Note that collection types are not supported here, in contrast to reflective injection points. For programmatically retrieving a list of beans matching a specific type, specify the actual bean type as an argument here and subsequently use ObjectProvider.orderedStream() or its lazy streaming/iteration options.

  返回:

  a corresponding provider handle

• containsBeanDefinition

  public boolean containsBeanDefinition​(String beanName)

  从类复制的说明: 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.

  指定者:

  从接口复制的说明: 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.

  指定者:

  getBeanDefinitionNames 在接口中 BeanDefinitionRegistry

  指定者:

  getBeanDefinitionNames 在接口中 ListableBeanFactory

  返回:

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

• getBeanNamesForType

  public String[] getBeanNamesForType​(ResolvableType type)

  从接口复制的说明: 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.

  指定者:

  getBeanNamesForType 在接口中 ListableBeanFactory

  参数:

  type - the generically typed class or interface to match

  返回:

  从接口复制的说明: 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.

  指定者:

  getBeanNamesForType 在接口中 ListableBeanFactory

  参数:

  type - the generically typed class or interface to match

  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.

  从接口复制的说明: 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.

  指定者:

  registerResolvableDependency 在接口中 ConfigurableListableBeanFactory

  参数:

  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.

  从类复制的说明: 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.

                         throws IllegalStateException

  从接口复制的说明: 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.

  指定者:

  registerSingleton 在接口中 SingletonBeanRegistry

  覆盖:
