All Implemented Interfaces:
TargetSourceCreator, Aware, BeanFactoryAware, DisposableBean
```
public class LazyInitTargetSourceCreator
extends AbstractBeanFactoryBasedTargetSourceCreator
```
TargetSourceCreator that enforces a LazyInitTargetSource for each bean that is defined as "lazy-init". This will lead to a proxy created for each of those beans, allowing to fetch a reference to such a bean without actually initializing the target bean instance.
To be registered as custom TargetSourceCreator for an auto-proxy creator, in combination with custom interceptors for specific beans or for the creation of lazy-init proxies only. For example, as autodetected infrastructure bean in an XML application context definition:
```
 <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
   <property name="customTargetSourceCreators">
     <list>
       <bean class="org.springframework.aop.framework.autoproxy.target.LazyInitTargetSourceCreator"/>
     </list>
   </property>
 </bean>

 <bean id="myLazyInitBean" class="mypackage.MyBeanClass" lazy-init="true">
   ...
 </bean>
```

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected AbstractBeanFactoryBasedTargetSource`	`createBeanFactoryBasedTargetSource(Class<?> beanClass, String beanName)`	Subclasses must implement this method to return a new AbstractPrototypeBasedTargetSource 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.
`protected boolean`	`isPrototypeBased()`	Return whether this TargetSourceCreator is prototype-based.

protected boolean isPrototypeBased()
```
    Description copied from class: AbstractBeanFactoryBasedTargetSourceCreator
    Return whether this TargetSourceCreator is prototype-based. The scope of the target bean definition will be set accordingly.
    Default is "true".
    Overrides:

                                                                                  String beanName)
```
    Description copied from class: AbstractBeanFactoryBasedTargetSourceCreator
    Subclasses must implement this method to return a new AbstractPrototypeBasedTargetSource 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 AbstractPrototypeBasedTargetSource: This class' implementation of getTargetSource() will do that.
    Specified by:
    createBeanFactoryBasedTargetSource in class AbstractBeanFactoryBasedTargetSourceCreator
    Parameters:
    beanClass - the class of the bean to create a TargetSource for
    beanName - the name of the bean
    Returns:
    the AbstractPrototypeBasedTargetSource, or null if we don't match this
