Class AbstractInterceptorDrivenBeanDefinitionDecorator

java.lang.Object

org.springframework.aop.config.AbstractInterceptorDrivenBeanDefinitionDecorator

All Implemented Interfaces:

org.springframework.beans.factory.xml.BeanDefinitionDecorator

public abstract class AbstractInterceptorDrivenBeanDefinitionDecorator
extends Object
implements org.springframework.beans.factory.xml.BeanDefinitionDecorator

Base implementation for BeanDefinitionDecorators wishing to add an interceptor to the resulting bean.

This base class controls the creation of the ProxyFactoryBean bean definition and wraps the original as an inner-bean definition for the target property of ProxyFactoryBean.

Chaining is correctly handled, ensuring that only one ProxyFactoryBean definition is created. If a previous BeanDefinitionDecorator already created the ProxyFactoryBean then the interceptor is simply added to the existing definition.

Subclasses have only to create the BeanDefinition to the interceptor that they wish to add.
