来源：互联网发布：主流社交软件编辑：程序博客网时间：2024/05/20 12:47

package com.apjept.bean.chapter;

@Service
public class Demo implements InitializingBean,DisposableBean,BeanPostProcessor{

@Override
public void afterPropertiesSet() throws Exception {
System.out.println("*********");
}

@Override
public void destroy() throws Exception {
System.out.println("%%%%%%%%%%%");
}

@Override
public Object postProcessAfterInitialization(Object arg0, String arg1)
   throws BeansException {
  System.out.println("****22222*****");
  return arg0;
}

@Override
public Object postProcessBeforeInitialization(Object arg0, String arg1)
   throws BeansException {
  System.out.println("*****111****");
  return arg0;
}

}

定义AspectJTestBean

package com.apjept.bean.chapter;

@Service
public class AspectJTestBean{

public String MyMethod(String loginInfo) {
System.out.println("Person login() " + "LoginInfo:" + loginInfo + this);
return " logining..."+loginInfo;
}

}

application.xml配置

<context:component-scan base-package="com.apjept.bean.chapter"/>

调用

AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("/applicationContext.xml");
ctx.registerShutdownHook();
ctx.getBean("aspectJTestBean");
