ibatisnet框架使用说明

2018-06-18 02:53:19来源：未知阅读 ()

ibatis配置文件主要包括三个 sqlmap.config，providers.config，database.config，注意所有文件生成操作都为嵌入的资源。其中database.config主要是配置数据库参数的一个config文件

<?xml version="1.0" encoding="utf-8" ?>
<settings>
    <!--   User application and configured property settings go here.-->
    <!-- To run tests, create a file named DataBase.config
         with your own value for datasource.
         (don't included it in the solution and don't commit it in SVN)
    -->
    <add key="userid" value="sa" /> <!--数据库连接登录名 -->
    <add key="password" value="sa" /><!--数据库连接密码 -->
    <add key="database" value="person" /><!--数据库名字 -->
    <add key="datasource" value="." /><!--服务器名-->
    <add key="selectKey" value="select @@IDENTITY as value" />
    <add key="directory" value="Maps" />
    <add key="useStatementNamespaces" value="false" />
</settings>

其次 providers.config 这个主要存放连接数据库的驱动程序主要有 oracle sqlserver等等。
最后讲解 sqlmap.config这个配置比较重要。

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

  <!-- Rem : If used via a DataAccess context, properties tag will be ignored
  <properties resource="../../database.config"/> -->
  <!--加载配置文件注意命名空间IBatisNetDemo-->
  <properties embedded="database.config, IBatisNetDemo"/>
  <settings>
    <setting useStatementNamespaces="${useStatementNamespaces}"/>
    <setting cacheModelsEnabled="true"/>
    <setting validateSqlMap="false"/>
  </settings>
 
  <!-- Optional if resource -->
  <providers embedded="providers.config,IBatisNetDemo"/>
    <!--加载配置文件注意命名空间IBatisNetDemo-->
  <!-- ==== SqlClient configuration =========    -->
  <!-- Rem : If used via a DataAccess context, database tag will be ignored -->
  <database>
    <!-- Optional ( default ) -->
    <!--加载数据库连接字符串这里连接sqlserver数据库-->
    <provider name="sqlServer1.1"/>
    <dataSource name="test" connectionString="data source=${datasource};database=${database};user id=${userid};password=${password};connection reset=false;connection lifetime=5; min pool size=1; max pool size=50"/>
  </database>

  <sqlMaps>
    <!-- user via embedded-->
    <!--加载配置文件注意命名空间IBatisNetDemo-->
    <sqlMap embedded="Map.SqlClient.Dep.xml,IBatisNetDemo"/>
    <sqlMap embedded="Map.SqlClient.Person.xml,IBatisNetDemo"/>
  </sqlMaps>
</sqlMapConfig>

其次讲解xml文件这里主要讲解两个xml文件，第一个Person.xml

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

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

  <alias>
    <typeAlias alias="Person" type="IBatisNetDemo.Domain.Person,IBatisNetDemo" /> <!--加载实体类，这里主要指下面要调用的实体类-->
  </alias>

  <resultMaps>  <!--返回数据解析的实体-->
    <resultMap id="SelectAllResult" class="Person">
      <result property="Id" column="PER_ID" />
      <result property="FirstName" column="PER_FIRST_NAME" />
      <result property="LastName" column="PER_LAST_NAME" />
      <result property="BirthDate" column="PER_BIRTH_DATE" />
      <result property="WeightInKilograms" column="PER_WEIGHT_KG" />
      <result property="HeightInMeters" column="PER_HEIGHT_M" />
      <result property="depid" column="DepID" />
    </resultMap>

  </resultMaps>

  <statements><!-- 这里主要写sql语句和存储过程-->

    <select id="SelectPersonByDepId" resultMap="SelectAllResult">
      select
      PER_ID,
      PER_FIRST_NAME,
      PER_LAST_NAME,
      PER_BIRTH_DATE,
      PER_WEIGHT_KG,
      PER_HEIGHT_M,
      DepID
      from PERSON where DepID=#DepID#
    </select>
    <select id="SelectAllPerson" resultMap="SelectAllResult">
      select
      PER_ID,
      PER_FIRST_NAME,
      PER_LAST_NAME,
      PER_BIRTH_DATE,
      PER_WEIGHT_KG,
      PER_HEIGHT_M,
      DepID
      from PERSON
    </select>

    <select id="SelectByPersonId" resultMap="SelectAllResult" parameterClass="Hashtable">
      select
      PER_ID,
      PER_FIRST_NAME,
      PER_LAST_NAME,
      PER_BIRTH_DATE,
      PER_WEIGHT_KG,
      PER_HEIGHT_M,
      DepID
      from PERSON
      <dynamic prepend="where"><!--动态添加sql语句条件-->
        <isParameterPresent>
          <isNotEmpty prepend="and" property="id" >
            PER_ID = '$id$'
          </isNotEmpty>
          <isNotEmpty prepend="and" property="name" >
            PER_FIRST_NAME LIKE '%$name$%'
          </isNotEmpty>
        </isParameterPresent>
      </dynamic>
    </select>

    <insert id="InsertPerson"  parameterclass="Person" >
      <selectKey property="Id" type="post" resultClass="int">
        ${selectKey}
      </selectKey>
      insert into Person
      ( PER_FIRST_NAME,
      PER_LAST_NAME,
      PER_BIRTH_DATE,
      PER_WEIGHT_KG,
      PER_HEIGHT_M)
      values
      (#FirstName#,#LastName#,#BirthDate#, #WeightInKilograms#, #HeightInMeters#)
    </insert>

    <update id="UpdatePerson"
                   parameterclass="Person">
      <![CDATA[ update Person set
      PER_FIRST_NAME =#FirstName#,
      PER_LAST_NAME =#LastName#,
      PER_BIRTH_DATE =#BirthDate#,
      PER_WEIGHT_KG=#WeightInKilograms#,
      PER_HEIGHT_M=#HeightInMeters#
      where
      PER_ID = #Id#　]]>
    </update>

    <delete id="DeletePerson" parameterclass="Person">
      delete from Person
      where
      PER_ID = #Id#
    </delete>

  </statements>
</sqlMap>

第二个xml文件 Dep.xml

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

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

  <alias>
    <typeAlias alias="Dep" type="IBatisNetDemo.Domain.Dep,IBatisNetDemo" />  


  </alias>

  <resultMaps>
    <resultMap id="SelectAllResultDep" class="Dep">
      <result property="DepId" column="DepID" />
      <result property="DepName" column="DepName" />
      <result property="list" column="DepID" select="SelectPersonByDepId" /><!--配置一对多关系，这里的select选择id为person.xml文件的id，注意这里id都是公用-->
    </resultMap>
  </resultMaps>

  <statements>
    <select id="SelectDepById" resultMap="SelectAllResultDep">
      select DepID,DepName from Dep where DepId=#DepID#
    </select>
  </statements>
</sqlMap>

其中一个为部门，一个为人员，两个之间关系为一对多的关系

配置文件讲解完过后我们来讲解怎么调用这个框架，首先要引用IBatisNet.Common.dll,IBatisNet.DataMapper.dll 两个文件

其实加载sqlmap对象

代码如下：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Reflection;
using System.Text;
using IBatisNet.DataMapper;
using IBatisNet.DataMapper.Configuration;
using IBatisNetDemo.Domain;

namespace IBatisNetDemo
{
    public class BaseDao<T> where T : class
    {
        private ISqlMapper sqlMap;

        //private string fileName = "sqlMap.Config";

        public BaseDao()
        {
            Assembly assembly = Assembly.Load("IBatisNetDemo");
            Stream stream = assembly.GetManifestResourceStream("IBatisNetDemo.sqlmap.config");

            DomSqlMapBuilder builder = new DomSqlMapBuilder();
            sqlMap = builder.Configure(stream);

        }


        public ISqlMapper SqlMap
        {
            get
            {
                return sqlMap;
            }
        }

        public IList<T> GetAllList(string key)
        {
            
            return SqlMap.QueryForList<T>(key, null);
            
        }
        public T GetModel(string key, object id)
        {

            return SqlMap.QueryForObject<T>(key, id);

        }

        public object Insert(string key, T model)
        {
            object o = null;
            o = sqlMap.Insert(key, model);
            return o;

        }
    }
}
