类 AbstractBeanFactoryTargetSourceCreator

java.lang.Object
cn.taketoday.aop.framework.autoproxy.target.AbstractBeanFactoryTargetSourceCreator
所有已实现的接口:
TargetSourceCreator, Aware, BeanFactoryAware, DisposableBean
直接已知子类:
LazyInitTargetSourceCreator, QuickTargetSourceCreator
public abstract class AbstractBeanFactoryTargetSourceCreator extends Object implements TargetSourceCreator, BeanFactoryAware, DisposableBean
Convenient superclass for TargetSourceCreator implementations that require creating multiple instances of a prototype bean.

Uses an internal BeanFactory to manage the target instances, copying the original bean definition to this internal factory. This is necessary because the original BeanFactory will just contain the proxy instance created through auto-proxying.

Requires running in an AbstractBeanFactory.

    • setBeanFactory

      public final void setBeanFactory(BeanFactory beanFactory)
      指定者:
      setBeanFactory 在接口中 BeanFactoryAware

    • getBeanFactory

      protected final BeanFactory getBeanFactory()
      Return the BeanFactory that this TargetSourceCreators runs in.

    • getTargetSource

      @Nullable public final TargetSource getTargetSource(Class<?> beanClass, String beanName)
      从接口复制的说明: TargetSourceCreator
      Create a special TargetSource for the given bean, if any.
      指定者:
      getTargetSource 在接口中 TargetSourceCreator
      参数:
      beanClass - the class of the bean to create a TargetSource for
      beanName - the name of the bean
      返回:
      a special TargetSource or null if this TargetSourceCreator isn't interested in the particular bean

    • getInternalBeanFactoryForBean

      protected StandardBeanFactory getInternalBeanFactoryForBean(String beanName)
      Return the internal BeanFactory to be used for the specified bean.
      参数:
      beanName - the name of the target bean
      返回:
      the internal BeanFactory to be used

    • buildInternalBeanFactory

      protected StandardBeanFactory buildInternalBeanFactory(ConfigurableBeanFactory containingFactory)
      Build an internal BeanFactory for resolving target beans.
      参数:
      containingFactory - the containing BeanFactory that originally defines the beans
      返回:
      an independent internal BeanFactory to hold copies of some target beans

    • destroy

      public void destroy()
      Destroys the internal BeanFactory on shutdown of the TargetSourceCreator.
      指定者:
      destroy 在接口中 DisposableBean

    • isPrototypeBased

      protected boolean isPrototypeBased()
      Return whether this TargetSourceCreator is prototype-based. The scope of the target bean definition will be set accordingly.

      Default is "true".

    • createBeanFactoryTargetSource

      @Nullable protected abstract AbstractBeanFactoryTargetSource createBeanFactoryTargetSource(Class<?> beanClass, String beanName)
      Subclasses must implement this method to return a new AbstractPrototypeTargetSource if they wish to create a custom TargetSource for this bean, or null if they are not interested it in, in which case no special target source will be created. Subclasses should not call setTargetBeanName or setBeanFactory on the AbstractPrototypeTargetSource: This class' implementation of getTargetSource() will do that.
      参数:
      beanClass - the class of the bean to create a TargetSource for
      beanName - the name of the bean
      返回:
      the AbstractPrototypeBasedTargetSource, or null if we don't match this
