java.lang.Object org.springframework.aop.target.AbstractBeanFactoryBasedTargetSource
public abstract class AbstractBeanFactoryBasedTargetSource
Base class for TargetSource
implementations
that are based on a Spring BeanFactory
,
delegating to Spring-managed bean instances.
Subclasses can create prototype instances or lazily access a
singleton target, for example. See LazyInitTargetSource
and
AbstractPrototypeBasedTargetSource
's subclasses for concrete strategies.
BeanFactory-based TargetSources are serializable. This involves
disconnecting the current target and turning into a SingletonTargetSource
.

public void setTargetBeanName(String targetBeanName)
The target bean should not be a singleton, else the same instance will
always be obtained from the factory, resulting in the same behavior as
provided by SingletonTargetSource
.

public void setTargetClass(Class targetClass)
Default is to detect the type automatically, through a getType
call on the BeanFactory (or even a full getBean
call as fallback).
