Spring.Net学习笔记(7)-事务

一、开发环境

操作系统：Win7

编译器：VS2010

二、涉及程序集

Spring.Core.dll

Spring.Data.dll

Common.Logging.dll

三、开发过程

1.项目结构

2.IAccountDao.cs

namespace Dao
{
    public interface IAccountDao
    {
        void Create(string name, string userName);

        void Delete(string userName);
    }
}

3.IUserDao.cs

namespace Dao
{
    public interface IUserDao
    {
        void Create(string name, int age);

        void Delete(string name);

        DataSet Get(string name);
    }
}

4.AccountDao.cs

namespace Dao
{
    public class AccountDao : AdoDaoSupport, IAccountDao
    {
        public void Create(string name, string userName)
        {
            AdoTemplate.ExecuteNonQuery(CommandType.Text,
                String.Format("INSERT INTO T_Account (UserName,    AccountName) VALUES ('{0}', '{1}')", userName, name));
        }

        public void Delete(string userName)
        {
            AdoTemplate.ExecuteNonQuery(CommandType.Text,
                String.Format("DELETE FROM T_Account WHERE UserName = '{0}'", userName));
        }
    }
}

5.UserDao.cs

namespace Dao
{
    public class UserDao : AdoDaoSupport, IUserDao
    {
        public void Create(string name, int age)
        {
            AdoTemplate.ExecuteNonQuery(CommandType.Text,
                string.Format("INSERT INTO T_User (UserName,    UserAge) VALUES ('{0}', {1})", name, age));
        }

        public void Delete(string name)
        {
            AdoTemplate.ExecuteNonQuery(CommandType.Text,
                string.Format("DELETE FROM T_User WHERE UserName = '{0}'", name));
        }

        public DataSet Get(string name)
        {
            return AdoTemplate.DataSetCreate(CommandType.Text,
                string.Format("SELECT * FROM T_User WHERE UserName = '{0}'", name));
        }
    }
}

6.IUserService.cs

namespace Service
{
    public interface IUserService
    {
        void SaveData(string name, int age, string accountName);

        void DeleteData(string name);

        DataSet Get(string name);
    }
}

7.UserService.cs

namespace Service
{
    public class UserService : IUserService
    {
        public IUserDao UserDao { get; set; }

        public IAccountDao AccountDao { get; set; }

        [Transaction]
        public void SaveData(string name, int age, string accountName)
        {
            UserDao.Create(name, age);
            AccountDao.Create(accountName, name);
        }

        [Transaction]
        public void DeleteData(string name)
        {
            UserDao.Delete(name);
            throw new Exception("测试数据是否回滚");
            AccountDao.Delete(name);
        }

        [Transaction(ReadOnly = true)]
        public DataSet Get(string name)
        {
            return UserDao.Get(name);
        }
    }
}

namespace SpringNetTrans
{
    class Program
    {
        static void Main(string[] args)
        {
            AdoTransaction();
