1，複製專案spring404 ，改名spring404-2，修改BankServiceImpl類，刪除宣告式事務的程式碼。宣告式事務管理的方式缺點是，事務程式碼嚴重嵌入邏輯程式碼中
package com.cruise.service.impl;

import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.support.TransactionCallbackWithoutResult;
import org.springframework.transaction.support.TransactionTemplate;

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

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，新增名稱空間，新增配置事務通知，新增配置事務切面，

</beans>

3，BankDaoImpl程式碼
package com.cruise.dao.impl;

import org.springframework.jdbc.core.namedparam.MapSqlParameterSource;
import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;

import com.cruise.dao.BankDao;

public class BankDaoImpl implements BankDao{

    private NamedParameterJdbcTemplate namedParameterJdbcTemplate;
   
    public void setNamedParameterJdbcTemplate(NamedParameterJdbcTemplate namedParameterJdbcTemplate) {
       this.namedParameterJdbcTemplate = namedParameterJdbcTemplate;
    }

    @Override
    public void InMoney(int money, int userid) {
       System.out.println(1/0);
       String sql ="update t_account set balance=balance+:money where id=:userid";
       MapSqlParameterSource msps= new MapSqlParameterSource();
       msps.addValue("money", money);
       msps.addValue("userid", userid);
       namedParameterJdbcTemplate.update(sql, msps);
      
    }

    @Override
    public void OutMoney(int money, int userid) {
       String sql ="update t_account set balance=balance-:money where id=:userid";
       MapSqlParameterSource msps= new MapSqlParameterSource();
       msps.addValue("money", money);
       msps.addValue("userid", userid);
       namedParameterJdbcTemplate.update(sql, msps);
    }
}

4，測試程式碼
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);
    }
}
