01_1_准备ibatis环境

1. 搭建环境：导入相关的jar包

mysql-connector-java-5.1.5-bin.jar(mysql)或者ojdbc6.jar(oracle)、ibatis-2.3.3.720.jar

2. 配置文件

2.1jdbc连接的属性文件

SqlMap.properties

 

driver=oracle.jdbc.driver.OracleDriver

url=jdbc:oracle:thin:@127.0.0.1:1521:orcl

username=scott

password=scott

2.2总配置文件

SqlMapConfig.xml

<!DOCTYPE sqlMapConfig        

    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"        

    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">  

<sqlMapConfig>  

    <properties resource="config/SqlMap.properties" />  

    <transactionManager type="JDBC">  

        <dataSource type="SIMPLE">  

            <property name="JDBC.Driver" value="${driver}" />  

            <property name="JDBC.ConnectionURL" value="${url}" />  

            <property name="JDBC.Username" value="${username}" />  

            <property name="JDBC.Password" value="${password}" />  

        </dataSource>  

    </transactionManager>  

    <sqlMap resource="config/map/Student.xml" />  

</sqlMapConfig>  

2.3每个实体的映射文件（map文件）

Student.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">  

<sqlMap>  

  <typeAlias alias="Student" type="entity.Student"/>

  <select id="selectAllStudent" resultClass="Student">

   select * from student

  </select>

</sqlMap>
