所有已实现的接口:

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.

从以下版本开始:

ProviderCreatingFactoryBean

public ProviderCreatingFactoryBean()

方法详细资料

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

AbstractFactoryBean.getObject()
