iBATIS代码生成分析

1.分析目录结构“tools”（或者说模板）

2.首先分析ibatorConfig.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE ibatorConfiguration PUBLIC "-//Apache Software Foundation//DTD Apache iBATIS Ibator Configuration 1.0//EN" "http://ibatis.apache.org/dtd/ibator-config_1_0.dtd" >
<ibatorConfiguration>

    <classPathEntry
        location="F:\sqljdbc.jar" />
    <ibatorContext id="context1" targetRuntime="Ibatis2Java5">

        <!--
      classPathEntry 指定数据库jdbc驱动jar包的绝对路径。
    -->

        <!--
            id 这个id可以在使用命令行运行Abator时指定，以单独处理某一个ibatorContext targetRuntime
            Ibatis2Java5 生成适合JDK5.0的类，另一个选项是 Ibatis2Java2，生成适合Java2的类。
        -->

        <ibatorPlugin
            type="org.apache.ibatis.ibator.plugins.RenameExampleClassPlugin">
            <property name="searchString" value="Example$" />
            <property name="replaceString" value="Example" />
        </ibatorPlugin>

        <!--
            ibatorPlugin 继承自IbatorPluginAdapter，包名必须是
            org.apache.ibatis.ibator.plugins，具体实现可以参考官方文档 必须有替换和被替换字符属性。
        -->
<!--
        <jdbcConnection driverClass="org.postgresql.Driver"
            connectionURL="jdbc:postgresql://127.0.0.1:5432/hibernateTest" userId="postgres"
            password="postgres" />
-->
        <jdbcConnection driverClass="com.microsoft.sqlserver.jdbc.SQLServerDriver"
            connectionURL="jdbc:sqlserver://127.0.0.1:1433;databaseName=PanaDatabase" userId="sa"
            password="sasa" />

        <!--
            driverClass 数据库驱动类 connectionURL 数据库连接地址 userId 用户 password 密码

            还可以使用以下格式添加数据库的其他连接属性 <property name="" value=""/>
        -->

        <javaTypeResolver>

            <property name="forceBigDecimals" value="false" />

            <!--
                默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer true，把JDBC DECIMAL 和
                NUMERIC 类型解析为java.math.BigDecimal
            -->

        </javaTypeResolver>

        <javaModelGenerator targetPackage="abator.model"
            targetProject="comboFramework/tools" />

        <!--
            targetProject 生成的Java Bean放置在哪个项目的哪个目录下 targetPackage 生成的Java Bean的包名
            一个有用的属性 <property name="trimStrings" value="true" /> 从数据库返回的值被清理前后的空格
            <property name="enableSubPackages" value="false" /> 是否在包名后加上scheme名称
        -->

        <sqlMapGenerator targetPackage="abator.sqlmap"
            targetProject="comboFramework/tools" />

        <!--
            targetProject 生成的 SqlMap.xml 文件放置在哪个项目的哪个目录下 targetPackage 生成的
            SqlMap.xml 文件的包名 <property name="enableSubPackages" value="false" />
            是否在包名后加上scheme名称
        -->

        <daoGenerator targetPackage="abator.dao" targetProject="comboFramework/tools"
            type="GENERIC-CI" />

        <table  tableName="InfoVoteItm"></table>

    </ibatorContext>
</ibatorConfiguration>

需要注意的几点是

1.指向的jdbc包是否正确或存在

    <classPathEntry
        location="F:\sqljdbc.jar" />
    <ibatorContext id="context1" targetRuntime="Ibatis2Java5">

2.数据库连接是否配置正确

        <jdbcConnection driverClass="com.microsoft.sqlserver.jdbc.SQLServerDriver"
            connectionURL="jdbc:sqlserver://127.0.0.1:1433;databaseName=PanaDatabase" userId="sa"
            password="sasa" />

3.指向的模板工具是否正确

        <!--
            targetProject 生成的Java Bean放置在哪个项目的哪个目录下 targetPackage 生成的Java Bean的包名
            一个有用的属性 <property name="trimStrings" value="true" /> 从数据库返回的值被清理前后的空格
            <property name="enableSubPackages" value="false" /> 是否在包名后加上scheme名称
        -->

        <sqlMapGenerator targetPackage="abator.sqlmap"
            targetProject="comboFramework/tools" />

        <!--
            targetProject 生成的 SqlMap.xml 文件放置在哪个项目的哪个目录下 targetPackage 生成的
            SqlMap.xml 文件的包名 <property name="enableSubPackages" value="false" />
            是否在包名后加上scheme名称
        -->

        <daoGenerator targetPackage="abator.dao" targetProject="comboFramework/tools"
            type="GENERIC-CI" />
        

4.指向需要生成的表

<table  tableName="InfoVoteItm"></table>

这里是单表（还没试过多个表一起生成呢，可以试试）

最终生成的结果如图

可以看出对iBATIS对表InfoVoteItm生成了三个模块即"sqlmap","model","dao"。

现在我们一个一个的来分析这三个部分。

在分析之前了解下InfoVoteItm表的结构

USE [PanaDatabase]
GO
/****** 对象:  Table [dbo].[InfoVoteItm]    脚本日期: 06/04/2012 16:22:55 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[InfoVoteItm](
    [EmpID] [nvarchar](250) COLLATE Chinese_PRC_CI_AS NULL,
    [InfoDetail_ID] [int] NULL,
    [VoteItmDate] [datetime] NULL CONSTRAINT [DF_InfoVoteItm_VoteItmDate]  DEFAULT (getdate())
) ON [PRIMARY]

A.首先我们来分析"sqlmap"这一部分对InfoVoteItm表生成的文件InfoVoteItm_SqlMap.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd" >

        )

    insert into InfoVoteItm

        EmpID

    values

    <!--

    select count(*) from InfoVoteItm
    <include refid="InfoVoteItm.ibatorgenerated_Example_Where_Clause" />
  </select>
  <update id="ibatorgenerated_updateByExampleSelective" >
    <!--

    -->
    update InfoVoteItm
    <dynamic prepend="set" >
      <isNotNull prepend="," property="record.empid" >
        EmpID = #record.empid:VARCHAR#
      </isNotNull>
      <isNotNull prepend="," property="record.infodetailId" >

    <!--
      WARNING - This element is automatically generated by Apache iBATIS ibator, do not modify.
      This element was generated on Wed Mar 09 16:57:25 CST 2011.
    -->
    update InfoVoteItm
    set EmpID = #record.empid:VARCHAR#,
      InfoDetail_ID = #record.infodetailId:INTEGER#,
      VoteItmDate = #record.voteitmdate:TIMESTAMP#
    <isParameterPresent >
      <include refid="InfoVoteItm.ibatorgenerated_Example_Where_Clause" />
    </isParameterPresent>
  </update>
</sqlMap>

可以看出对表InfoVoteItm做了实体映射（实现增加add，删除delete，修改update，查询select）

首先分析下映射实体类

  <resultMap id="ibatorgenerated_BaseResultMap" class="abator.model.Infovoteitm" >
    <!--
      WARNING - This element is automatically generated by Apache iBATIS ibator, do not modify.
      This element was generated on Wed Mar 09 16:57:25 CST 2011.
    -->
    <result column="EmpID" property="empid" jdbcType="VARCHAR" />
    <result column="InfoDetail_ID" property="infodetailId" jdbcType="INTEGER" />
    <result column="VoteItmDate" property="voteitmdate" jdbcType="TIMESTAMP" />
  </resultMap>

其中"id"起标识的作用，"class"映射由iBATIS生成的实体类（路径指向，若要移动该文件此处要及得修改）

"column"可以随意定义但前提是实体类中有相匹配的字段即"property","jdbcType"设置字段属性（属性与数据库字段类型相同）

查询（可以看出resultMap是对实体类的一种映射，如果查询select中的字段在实体类中未定义则会出现异常，parameterClass指向的是参数需要注意与class的区别）

  <select id="ibatorgenerated_selectByExample" resultMap="ibatorgenerated_BaseResultMap" parameterClass="abator.model.InfovoteitmExample" >
    <!--
      WARNING - This element is automatically generated by Apache iBATIS ibator, do not modify.
      This element was generated on Wed Mar 09 16:57:25 CST 2011.
    -->
    select EmpID, InfoDetail_ID, VoteItmDate
    from InfoVoteItm
    <isParameterPresent >
      <include refid="InfoVoteItm.ibatorgenerated_Example_Where_Clause" />
      <isNotNull property="orderByClause" >
        order by $orderByClause$
      </isNotNull>
    </isParameterPresent>
  </select>

查询返回结果值

  <select id="ibatorgenerated_countByExample" parameterClass="abator.model.InfovoteitmExample" resultClass="java.lang.Integer" >
    <!--
      WARNING - This element is automatically generated by Apache iBATIS ibator, do not modify.
      This element was generated on Wed Mar 09 16:57:25 CST 2011.
    -->
    select count(*) from InfoVoteItm
    <include refid="InfoVoteItm.ibatorgenerated_Example_Where_Clause" />
  </select>

删除

  <delete id="ibatorgenerated_deleteByExample" parameterClass="abator.model.InfovoteitmExample" >
    <!--
      WARNING - This element is automatically generated by Apache iBATIS ibator, do not modify.
      This element was generated on Wed Mar 09 16:57:25 CST 2011.
    -->
    delete from InfoVoteItm
    <include refid="InfoVoteItm.ibatorgenerated_Example_Where_Clause" />
  </delete>

添加

1.添加所有项

  <insert id="ibatorgenerated_insert" parameterClass="abator.model.Infovoteitm" >
    <!--
      WARNING - This element is automatically generated by Apache iBATIS ibator, do not modify.
      This element was generated on Wed Mar 09 16:57:25 CST 2011.
    -->
    insert into InfoVoteItm (EmpID, InfoDetail_ID, VoteItmDate)
    values (#empid:VARCHAR#, #infodetailId:INTEGER#, #voteitmdate:TIMESTAMP#)
  </insert>

2.选择性添加

  <insert id="ibatorgenerated_insertSelective" parameterClass="abator.model.Infovoteitm" >
    <!--
      WARNING - This element is automatically generated by Apache iBATIS ibator, do not modify.
      This element was generated on Wed Mar 09 16:57:25 CST 2011.
    -->
    insert into InfoVoteItm
    <dynamic prepend="(" >
      <isNotNull prepend="," property="empid" >
        EmpID
      </isNotNull>
      <isNotNull prepend="," property="infodetailId" >
        InfoDetail_ID
      </isNotNull>
      <isNotNull prepend="," property="voteitmdate" >
        VoteItmDate
      </isNotNull>
      )
    </dynamic>
    values
    <dynamic prepend="(" >
      <isNotNull prepend="," property="empid" >
        #empid:VARCHAR#
      </isNotNull>
      <isNotNull prepend="," property="infodetailId" >
        #infodetailId:INTEGER#
      </isNotNull>
      <isNotNull prepend="," property="voteitmdate" >
        #voteitmdate:TIMESTAMP#
      </isNotNull>
      )
    </dynamic>
  </insert>

变更

1.选择性变更（条件可选）

  <update id="ibatorgenerated_updateByExampleSelective" >
    <!--
      WARNING - This element is automatically generated by Apache iBATIS ibator, do not modify.
      This element was generated on Wed Mar 09 16:57:25 CST 2011.
    -->
    update InfoVoteItm
    <dynamic prepend="set" >
      <isNotNull prepend="," property="record.empid" >
        EmpID = #record.empid:VARCHAR#
      </isNotNull>
      <isNotNull prepend="," property="record.infodetailId" >
        InfoDetail_ID = #record.infodetailId:INTEGER#
      </isNotNull>
      <isNotNull prepend="," property="record.voteitmdate" >
        VoteItmDate = #record.voteitmdate:TIMESTAMP#
      </isNotNull>
    </dynamic>
    <isParameterPresent >
      <include refid="InfoVoteItm.ibatorgenerated_Example_Where_Clause" />
    </isParameterPresent>
  </update>

2.条件必须

  <update id="ibatorgenerated_updateByExample" >
    <!--
      WARNING - This element is automatically generated by Apache iBATIS ibator, do not modify.
      This element was generated on Wed Mar 09 16:57:25 CST 2011.
    -->
    update InfoVoteItm
    set EmpID = #record.empid:VARCHAR#,
      InfoDetail_ID = #record.infodetailId:INTEGER#,
      VoteItmDate = #record.voteitmdate:TIMESTAMP#
    <isParameterPresent >
      <include refid="InfoVoteItm.ibatorgenerated_Example_Where_Clause" />
    </isParameterPresent>
  </update>

"model"是对实体类的封装就不说了，看下"dao"层。

"dao"层生成了两个文件InfovoteitmDAO是接口类对方法的声明（包括增，删，改，查）而InfovoteitmDAOImpl是类是对InfovoteitmDAO接口方法的

实现。
