1，複製專案spring404 ，改名spring404-3。修改BankServiceImpl類，添加註解，
package com.cruise.service.impl;

import org.springframework.transaction.annotation.Transactional;

import com.cruise.dao.BankDao;
import com.cruise.service.BankService;

@Transactional
public class BankServiceImpl implements

 BankService{

    private BankDao bankDao;
    
    public void setBankDao(BankDao bankDao) {
       this.bankDao = bankDao;
    }
    
    @Override
    public void transferAccount(int money, int userA, int userB) {
       
              bankDao.OutMoney(money, userA);
              bankDao.InMoney(money, userB);
    }
}
2，修改beans.xml檔案，刪除配置事務通知，刪除配置事務切面。添加註解驅動。
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</bean>

<bean id="bankService" class="com.cruise.service.impl.BankServiceImpl">
    <property name="bankDao" ref="bankDao1"></property>
</bean>
</beans>
3，測試-執行
package com.cruise.test;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.cruise.service.BankService;

public class T {
    
    public static void main(String[] args) {
       ClassPathXmlApplicationContext CPXAC=new ClassPathXmlApplicationContext("beans.xml");
       BankService  bankService = (BankService) CPXAC.getBean("bankService");
       bankService.transferAccount(120, 1, 2);
    }
}
