Class AbstractInterceptorDrivenBeanDefinitionDecorator

java.lang.Object
  org.springframework.aop.config.AbstractInterceptorDrivenBeanDefinitionDecorator

All Implemented Interfaces:

BeanDefinitionDecorator

public abstract class AbstractInterceptorDrivenBeanDefinitionDecorator
extends java.lang.Object
implements 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.

2.0

decorate

public final BeanDefinitionHolder decorate(org.w3c.dom.Node node,
                                           BeanDefinitionHolder definitionHolder,
                                           ParserContext parserContext)

Description copied from interface: BeanDefinitionDecorator

Parse the specified Node (either an element or an attribute) and decorate the supplied BeanDefinition, returning the decorated definition.

Implementations may choose to return a completely new definition, which will replace the original definition in the resulting BeanFactory.

The supplied ParserContext can be used to register any additional beans needed to support the main definition.

Specified by:

decorate in interface BeanDefinitionDecorator

addInterceptorNameToList

private void addInterceptorNameToList(java.lang.String interceptorName,
                                      BeanDefinition beanDefinition)

isProxyFactoryBeanDefinition

private boolean isProxyFactoryBeanDefinition(BeanDefinition existingDefinition)

getInterceptorNameSuffix

protected java.lang.String getInterceptorNameSuffix(BeanDefinition interceptorDefinition)

createInterceptorDefinition

protected abstract BeanDefinition createInterceptorDefinition(org.w3c.dom.Node node)

Subclasses should implement this method to return the BeanDefinition for the interceptor they wish to apply to the bean being decorated.
