配置文件使用aop思想進(jìn)行配置

一挨摸、步驟

（1）配置事務(wù)管理器

（2）配置事務(wù)的增強(qiáng)

（3）配置切入點(diǎn)和切面

二孩革、代碼

Service層OrdersService.java

import org.springframework.beans.factory.annotation.Autowired;

import work.zhangdoudou.Dao.OrdersDao;

public class OrdersService {
    
    @Autowired
    private OrdersDao ordersDao;
    
    /*
     * 調(diào)用dao層
     * 業(yè)務(wù)邏輯，寫轉(zhuǎn)賬業(yè)務(wù)
     */
    public void accountMoney(String name1,String name2,Integer money) {
        //張三少1000塊錢
        ordersDao.lessMoney(name1,money);
        
        //李四多1000快錢
        ordersDao.moreMoney(name2,money);
    }
}

dao層OrdersDao.java

package work.zhangdoudou.Dao;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;

public class OrdersDao {
    
    @Autowired
    private JdbcTemplate jdbcTemplate;
    /*
     * 對(duì)數(shù)據(jù)庫(kù)操作得运，不屑業(yè)務(wù)
     */
    
    //張三少錢的方法
    public void lessMoney(String name,Integer money) {
        String sql="UPDATE account SET salary=salary-? WHERE u_name=?";
        jdbcTemplate.update(sql,money,name);
    }
    
    
    //李四多錢的方法
    public void moreMoney(String name,int money) {
        String sql="UPDATE account SET salary=salary+? WHERE u_name=?";
        jdbcTemplate.update(sql,money,name);
    }
}
