- - org.springframework.beans.factory.config.ProviderCreatingFactoryBean

所有已实现的接口:
Aware, BeanClassLoaderAware, BeanFactoryAware, DisposableBean, FactoryBean<Provider<Object>>, InitializingBean
```
public class ProviderCreatingFactoryBean
extends AbstractFactoryBean<Provider<Object>>
```
A FactoryBean implementation that returns a value which is a JSR-330 Provider that in turn returns a bean sourced from a BeanFactory.
This is basically a JSR-330 compliant variant of Spring's good old ObjectFactoryCreatingFactoryBean. It can be used for traditional external dependency injection configuration that targets a property or constructor argument of type javax.inject.Provider, as an alternative to JSR-330's @Inject annotation-driven approach.

`void`	`afterPropertiesSet()`	Eagerly create the singleton instance, if necessary.
`protected Provider<Object>`	`createInstance()`	Template method that subclasses must override to construct the object returned by this factory.
`Class<?>`	`getObjectType()`	This abstract method declaration mirrors the method in the FactoryBean interface, for a consistent offering of abstract template methods.
`void`	`setTargetBeanName(String targetBeanName)`	Set the name of the target bean.

  - setTargetBeanName
```
public void setTargetBeanName(String targetBeanName)
```
    Set the name of the target bean.
    The target does not have to be a non-singleton bean, but realistically always will be (because if the target bean were a singleton, then said singleton bean could simply be injected straight into the dependent object, thus obviating the need for the extra level of indirection afforded by this factory approach).
  - afterPropertiesSet
```
public void afterPropertiesSet()
                        throws Exception
```
    从类复制的说明: AbstractFactoryBean
    Eagerly create the singleton instance, if necessary.
    指定者:
    afterPropertiesSet 在接口中 InitializingBean
    覆盖:
    afterPropertiesSet 在类中 AbstractFactoryBean<Provider<Object>>
    抛出:
    Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails for any other reason
  - getObjectType
```
public Class<?> getObjectType()
```
    从类复制的说明: AbstractFactoryBean
    This abstract method declaration mirrors the method in the FactoryBean interface, for a consistent offering of abstract template methods.
    指定者:
    getObjectType 在接口中 FactoryBean<Provider<Object>>
    指定者:
    getObjectType 在类中 AbstractFactoryBean<Provider<Object>>
    返回:
    the type of object that this FactoryBean creates, or null if not known at the time of the call
    另请参阅:
    FactoryBean.getObjectType()
  - createInstance
```
protected Provider<Object> createInstance()
```
    从类复制的说明: AbstractFactoryBean
    Template method that subclasses must override to construct the object returned by this factory.
    Invoked on initialization of this FactoryBean in case of a singleton; else, on each AbstractFactoryBean.getObject() call.
    指定者:
    createInstance 在类中 AbstractFactoryBean<Provider<Object>>
    返回:
    the object returned by this factory
    另请参阅:
    AbstractFactoryBean.getObject()
