public class: LazyInitTargetSourceCreator [javadoc | source]

java.lang.Object
   org.springframework.aop.framework.autoproxy.target.AbstractBeanFactoryBasedTargetSourceCreator
      org.springframework.aop.framework.autoproxy.target.LazyInitTargetSourceCreator

All Implemented Interfaces:
DisposableBean, BeanFactoryAware, TargetSourceCreator

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 initialized 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>
