Class StaticListableBeanFactory

java.lang.Object
org.springframework.beans.factory.support.StaticListableBeanFactory
All Implemented Interfaces:
BeanFactory, ListableBeanFactory

public class StaticListableBeanFactory extends Object implements ListableBeanFactory
Static BeanFactory implementation which allows one to register existing singleton instances programmatically.

Does not have support for prototype beans or aliases.

Serves as an example for a simple implementation of the ListableBeanFactory interface, managing existing bean instances rather than creating new ones based on bean definitions, and not implementing any extended SPI interfaces (such as ConfigurableBeanFactory).

For a full-fledged factory based on bean definitions, have a look at DefaultListableBeanFactory.

  • Method Details

    • addBean

      public void addBean(String name, Object bean)
      Add a new singleton bean.

      Will overwrite any existing instance for the given name.

      Parameters:
      name - the name of the bean
      bean - the bean instance
    • getBean

      public Object getBean(String name) throws BeansException
      Description copied from interface: BeanFactory
      Return an instance, which may be shared or independent, of the specified bean.

      This method allows a Spring BeanFactory to be used as a replacement for the Singleton or Prototype design pattern. Callers may retain references to returned objects in the case of Singleton beans.

      Translates aliases back to the corresponding canonical bean name.

      Will ask the parent factory if the bean cannot be found in this factory instance.

      Specified by:
      getBean in interface BeanFactory
      Parameters:
      name - the name of the bean to retrieve
      Returns:
      an instance of the bean. Note that the return value will never be null but possibly a stub for null returned from a factory method, to be checked via equals(null). Consider using BeanFactory.getBeanProvider(Class) for resolving optional dependencies.
      Throws:
      NoSuchBeanDefinitionException - if there is no bean with the specified name
      BeansException - if the bean could not be obtained
    • getBean

      public <T> T getBean(String name, @Nullable Class<T> requiredType) throws BeansException
      Description copied from interface: BeanFactory
      Return an instance, which may be shared or independent, of the specified bean.

      Behaves the same as BeanFactory.getBean(String), but provides a measure of type safety by throwing a BeanNotOfRequiredTypeException if the bean is not of the required type. This means that ClassCastException can't be thrown on casting the result correctly, as can happen with BeanFactory.getBean(String).

      Translates aliases back to the corresponding canonical bean name.

      Will ask the parent factory if the bean cannot be found in this factory instance.

      Specified by:
      getBean in interface BeanFactory
      Parameters:
      name - the name of the bean to retrieve
      requiredType - type the bean must match; can be an interface or superclass
      Returns:
      an instance of the bean. Note that the return value will never be null. In case of a stub for null from a factory method having been resolved for the requested bean, a BeanNotOfRequiredTypeException against the NullBean stub will be raised. Consider using BeanFactory.getBeanProvider(Class) for resolving optional dependencies.
      Throws:
      NoSuchBeanDefinitionException - if there is no such bean definition
      BeanNotOfRequiredTypeException - if the bean is not of the required type
      BeansException - if the bean could not be created
    • getBean

      public Object getBean(String name, 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.

      Specified by:
      getBean in interface BeanFactory
      Parameters:
      name - the name of the bean to retrieve
      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
    • 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:
    • 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
    • getBeanProvider

      public <T> ObjectProvider<T> getBeanProvider(Class<T> requiredType) throws BeansException
      Description copied from interface: BeanFactory
      Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options.

      For matching a generic type, consider BeanFactory.getBeanProvider(ResolvableType).

      Specified by:
      getBeanProvider in interface BeanFactory
      Parameters:
      requiredType - type the bean must match; can be an interface or superclass
      Returns:
      a corresponding provider handle
      Throws:
      BeansException
      See Also:
    • getBeanProvider

      public <T> ObjectProvider<T> getBeanProvider(ResolvableType requiredType)
      Description copied from interface: BeanFactory
      Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options. This variant allows for specifying a generic type to match, similar to reflective injection points with generic type declarations in method/constructor parameters.

      Note that collections of beans 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.

      Also, generics matching is strict here, as per the Java assignment rules. For lenient fallback matching with unchecked semantics (similar to the ┬┤unchecked┬┤ Java compiler warning), consider calling BeanFactory.getBeanProvider(Class) with the raw type as a second step if no full generic match is available with this variant.

      Specified by:
      getBeanProvider in interface BeanFactory
      Parameters:
      requiredType - type the bean must match; can be a generic type declaration
      Returns:
      a corresponding provider handle

    • containsBean

      public boolean containsBean(String name)
      Description copied from interface: BeanFactory
      Does this bean factory contain a bean definition or externally registered singleton instance with the given name?

      If the given name is an alias, it will be translated back to the corresponding canonical bean name.

      If this factory is hierarchical, will ask any parent factory if the bean cannot be found in this factory instance.

      If a bean definition or singleton instance matching the given name is found, this method will return true whether the named bean definition is concrete or abstract, lazy or eager, in scope or not. Therefore, note that a true return value from this method does not necessarily indicate that BeanFactory.getBean(java.lang.String) will be able to obtain an instance for the same name.

      Specified by:
      containsBean in interface BeanFactory
      Parameters:
      name - the name of the bean to query
      Returns:
      whether a bean with the given name is present
    • isSingleton

      public boolean isSingleton(String name) throws NoSuchBeanDefinitionException
      Description copied from interface: BeanFactory
      Is this bean a shared singleton? That is, will BeanFactory.getBean(java.lang.String) always return the same instance?

      Note: This method returning false does not clearly indicate independent instances. It indicates non-singleton instances, which may correspond to a scoped bean as well. Use the BeanFactory.isPrototype(java.lang.String) operation to explicitly check for independent instances.

      Translates aliases back to the corresponding canonical bean name.

      Will ask the parent factory if the bean cannot be found in this factory instance.

      Specified by:
      isSingleton in interface BeanFactory
      Parameters:
      name - the name of the bean to query
      Returns:
      whether this bean corresponds to a singleton instance
      Throws:
      NoSuchBeanDefinitionException - if there is no bean with the given name
      See Also:
    • isPrototype

      public boolean isPrototype(String name) throws NoSuchBeanDefinitionException
      Description copied from interface: BeanFactory
      Is this bean a prototype? That is, will BeanFactory.getBean(java.lang.String) always return independent instances?

      Description copied from interface: ListableBeanFactory
      Return a provider for the specified bean, allowing for lazy on-demand retrieval of instances, including availability and uniqueness options.
      Specified by:
      getBeanProvider in interface ListableBeanFactory
      Parameters:
      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.

    • getBeanNamesForType

      public String[] getBeanNamesForType(@Nullable 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 generically typed class or interface to match
      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(@Nullable ResolvableType type, boolean includeNonSingletons, boolean allowEagerInit)
      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 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.
      Returns:
      the names of beans (or objects created by FactoryBeans) matching the given object type (including subclasses), or an empty array if none
