     <aop:declare-parents                types-matching="com.itany.service.IPersonService+"                implement-interface="com.itany.service.IIntroduceService"                default-impl="com.itany.service.impl.IIntroduceServiceImpl"/>

Description

• Configure under <aop:aspect> tab </aop:aspect>
• Types-matching: Match the target object expression that needs to be introduced into the interface;
• Implement-interface: Defines the interfaces that need to be introduced;
• Default-impl and Delegate-ref: Define the default implementation of the introduction interface, select one

Instance:

        ApplicationContext act=new ClassPathXmlApplicationContext("beans.xml");        IIntroduceService introduceService = (IIntroduceService) act.getBean("personService");        introduceService.introduce("testintroduce");        ((IPersonService) introduceService).save();

In terms of understanding, this configuration realizes that the Introduceservice inherits the Personservice
