Ibatis.Net 学习手记一 简单的Demo

Ibatis.Net 学习手记  

    Wednesday, December 07, 2011

最近在做游戏推广的需求，趁公司给了不少充足的时间...再一次看了下自己以前学过的IbatisDemo,同时拿出来分享一下

Ibatis.Net的官方文档地址为 http://www.mybatis.org/dotnet.html  

下面晒一下我简单的Demo代码 

 Demo 中引用Castle.DynamicProxy.dll

                   IbatisNet.Common.dll

                   IbatisNet.Common.Logging.Log4Net.dll

                   IbatisNet.DataMapper.dll

                   log4net. dll

providers.config 是各类数据库mysql、sql server、Orcale的驱动配置文件，官方里面已经给出

SqlMap.config 需要配置一下：

<providers resource="providers.config" />  

一看就知道是引用providers.config配置文件

 <database>
    <provider name="sqlServer2005"></provider>
    <dataSource name="IBatisNet"  connectionString="server=localhost;database=IBatisDB;user id=sa;password=123;connection reset=false;"/>
  </database>

数据库方面的配置，也很容易知道不需要细讲

  <sqlMaps>
    <sqlMap resource="Person.xml" />
  </sqlMaps>

将sql映射写到外部文件，其实可以直接在SqlMap.config里面写的，不过项目大的话不建议这么做。

 接下来是person.xml里面的配置了...其实就是映射一下属性跟数据库表， 里面有

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

<sqlMap namespace="IBatisNetDemo" xmlns="http://ibatis.apache.org/mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >



  <alias>
    <typeAlias alias="Person" type="IBatisNetDemo.Person,IBatisNetDemo" />
  </alias>

  <statements>
    <select id="SelectAll" resultMap="SelectAllResult" >
      select
      Id,Name,Password
      from Person
    </select>
    <update id ="UpdatePerson" parameterClass="Person">
      Update Person
      set Name=#Name#
      where Password=#Password#
    </update>
    <select id="SelectByPassword" resultClass="Person" parameterClass="string">
      select Name,Password from Person where Password=#value#
    </select>
    <insert id="InsertPerson" parameterClass="Person">
      INSERT INTO Person
      (
      [Name],
      [Password]
      )
      VALUES
      (
      #Name#,
      #Password#
      )
    </insert>
    <delete id="DeletePersonByPassword" parameterClass="string">
      delete from Person where Password=#value#
    </delete>
    <delete id="DeletePerson" parameterClass="Person">
      delete from Person where Name=#Name# and Password=#Password#
    </delete>
    <procedure id="PrcInsertPerson" parameterMap="personSwap">
      InsertPerson
    </procedure>
    <procedure id="PrcInsertPersonBackID" parameterMap="personSwapTwo">
      InsertPersonBackID
    </procedure>
    <procedure id="PrcSelectPersonByName" parameterMap="personSwapThree" resultMap="personSwapThree">
      SelectPersonByName
    </procedure>
  </statements>
  

  <parameterMaps>
    <parameterMap id="personSwap" class="Person">
      <parameter property="Name" column="Name" />
      <parameter property="Password" column="Password" />
    </parameterMap>

    <parameterMap id="personSwapThree" class="Person">
      <parameter property="Name" column="Name" />
    </parameterMap>

    <parameterMap id="personSwapTwo" class="Person">
      <parameter property="Name" column="Name" />
      <parameter property="Password" column="Password" />
      <parameter property="ID" column="ID"  direction="Output" /> 
    </parameterMap>
  </parameterMaps>

  <resultMaps >

    <resultMap id="SelectAllResult" class="Person">
      <result property="ID" column="Id" />
      <result property="Name" column="Name" />
      <result property="Password" column="Password" />
    </resultMap>

    <resultMap id="personSwapThree" class="Person">
      <result property="Name" column="Name" />
      <result property="Password" column="Password" />
      <result property="ID" column="ID" />
    </resultMap>

  </resultMaps>

学习用的，所以只测试了下增删改查、还有调用存储过程等的不同方式实现方法。

实现的形式也只有一种，个人觉得会一种就够了，学样东西没问题一看所有方式都要会。想要的话自己看官方文档就好了。

          gvPersonData.DataSource = plist;
          gvPersonData.DataBind();
        }

    }

 看过的人都会觉得这样的实现方式相当简单，确实在我之前跟进一个项目时也用到了Ibatis，记得人家还特意封装了下Ibatis。

而Ibatis给我的感觉还是比较多的配置。配置这些都是简单的事情。我也刚学不久，还是先把理论下下来，呵呵！
