类 AbstractPrototypeTargetSource

java.lang.Object

infra.aop.target.AbstractBeanFactoryTargetSource

infra.aop.target.AbstractPrototypeTargetSource

所有已实现的接口:

TargetClassAware, TargetSource, infra.beans.factory.Aware, infra.beans.factory.BeanFactoryAware, Serializable

直接已知子类:

AbstractPoolingTargetSource, PrototypeTargetSource, ThreadLocalTargetSource

public abstract class AbstractPrototypeTargetSource
extends AbstractBeanFactoryTargetSource

Base class for dynamic TargetSource implementations that create new prototype bean instances to support a pooling or new-instance-per-invocation strategy.

Such TargetSources must run in a BeanFactory, as it needs to call the getBean method to create a new prototype instance. Therefore, this base class extends AbstractBeanFactoryTargetSource.

从以下版本开始:

3.0

方法详细资料

setBeanFactory

public void setBeanFactory(infra.beans.factory.BeanFactory beanFactory)
                    throws infra.beans.BeansException

从类复制的说明: AbstractBeanFactoryTargetSource

Set the owning BeanFactory. We need to save a reference so that we can use the getBean method on every invocation.

指定者:

setBeanFactory 在接口中 infra.beans.factory.BeanFactoryAware

覆盖:

setBeanFactory 在类中 AbstractBeanFactoryTargetSource

抛出:

infra.beans.BeansException

newPrototypeInstance

protected Object newPrototypeInstance()

Subclasses should call this method to create a new prototype instance.

destroyPrototypeInstance

protected void destroyPrototypeInstance(Object target)

Subclasses should call this method to destroy an obsolete prototype instance.

参数:

target - the bean instance to destroy

readObject

private void readObject(ObjectInputStream ois)
                 throws IOException,
ClassNotFoundException

抛出:

IOException

ClassNotFoundException

writeReplace

protected Object writeReplace()
                       throws ObjectStreamException

Replaces this object with a SingletonTargetSource on serialization. Protected as otherwise it won't be invoked for subclasses. (The writeReplace() method must be visible to the class being serialized.)

With this implementation of this method, there is no need to mark non-serializable fields in this class or subclasses as transient.

抛出:

ObjectStreamException
