Ibatis.Net 入门学习(一)

由于工作需要，项目里用的是Ibatis.Net。所以就花时间学习学习，做做笔记吧。

1、打开SQLServer 2008，建一个数据库Test，一张表Person，添加入数据如下：

2、打开Vs2015， 新建一个控制台应用程序和两个类库项目如下：

其中，DAO是数据访问层，Model是实体层。然后DAO层需要引入Ibatis.Net的引用，这里使用NuGet添加：

其中PersonDAO的代码如下:

public class PersonDao
    {
        public IList<PersonModel> GetList()
        {
            ISqlMapper mapper = Mapper.Instance();
            IList<PersonModel> ListPerson = mapper.QueryForList<PersonModel>("SelectAllPerson", null);//这个"SelectAllPerson"就是xml映射文件的Id
            return ListPerson;
        }
    }
View Code

PersonModel代码如下：

 public class PersonModel
    {
        public int Id { get; set; }

        public string Name { get; set; }
    }
View Code

3、配置(包括xml映射文件,SqlMap.config,providers.config)

首先新建SqlMap.config，providers.config，Person.xml 。 在控制台程序中，将它们放到 bin\Debug 目录里。

SqlMap.config如下：

<?xml version="1.0" encoding="utf-8"?>
<sqlMapConfig
  xmlns="http://ibatis.apache.org/dataMapper"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  <!--<properties resource="../../../properties.config"/>这个东西是变量用的，这里以最简单的实现说明，因此注释-->

  <settings>
    <setting useStatementNamespaces="false"/>
  </settings>

  <providers resource="providers.config"/>

  <!--数据库连接字符串-->
  <database>
    <provider name="sqlServer2.0"/>
    <dataSource name="Test" connectionString="server=...;uid=...;pwd=...;database=Test"/>
  </database>

  <sqlMaps>
    <sqlMap resource="Person.xml" />
    <!--这个是指定映射文件的位置-->
  </sqlMaps>

</sqlMapConfig>
View Code

映射文件Person.xml：

<?xml version="1.0" encoding="utf-8" ?>
<sqlMap namespace="Ibatis" xmlns="http://ibatis.apache.org/mapping" xmlns:xls="http://www.w3.org/2001/XMLSchema-instance">
  <statements>
    <select id="SelectAllPerson" resultClass="IbatisNetModel.PersonModel">
      <!--这个Id在程序中会用到，resultClass是实体类所在的程序位置(带命名空间)-->
      select * from person
    </select>
  </statements>
</sqlMap>
View Code

最后是Providers.config。根据你使用的数据库，将文件中提供版本的enabled="true"就可以了，此处我用“sqlServer2.0”的，可以把其它全部删除(不删除也可以)。

<?xml version="1.0" encoding="utf-8"?>

Program.cs代码如下：

static void Main(string[] args)
        {
            PersonDAO dao = new PersonDAO();
            IList<PersonModel> listPerson = dao.GetList();
            foreach (PersonModel p in listPerson)
            {
                Console.WriteLine(p.Id +" - "+ p.Name);
            }

            Console.ReadKey();
        }
View Code

运行程序，显示结果如下：

上面就是Ibatis.Net的一个简单的Demo，下篇会继续学习其它要点

对于上面的程序，将数据库由SQLServer改为Oracle，上面不用改代码，只需要将providers.config文件name="oracle10.1"的enabled="true"，SqlMap.cofig里的database节点改为对应Oracle的连接字符串就行
