OOP编程iBatis 学习笔记之－ 环境配置及简单例子测试

本人使用MYSQL数据库做为测试例子 ，因为本例子简单，故没有将生成表的代码贴上

环境配置

1. 导入ibatis-2.3.4.726.jar mysql-connector-java-5.1.6-bin.jar

导入配置文件SqlMapConfig.xml

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

<!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="com/itcast/SqlMap.properties"/>

<transactionManager type="JDBC">

<dataSource type="SIMPLE">

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

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

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

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

</dataSource>

</transactionManager>

<sqlMap resource="com/it/Note.xml"/>

</sqlMapConfig>

SqlMap.properties

driver=com.mysql.jdbc.Driver

url=jdbc:mysql://127.0.0.1/test

username=root

password=admin



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="Note" type="com.it.Student"/>

<select id="selectAllNote” resultClass=" Note">

select *

from student

</select>

</sqlMap>



2. 建立对应表-类文件

3. package com.it;

4.

5. import java.sql.Date;

6. //Author:meetweb@sohu.com

7. public class Note {

8. private int sid=0;

9. private String sname=null;

10. private String major=null;

11. private Date birth=null;

12. }

执行文件

package com.it;

import java.io.IOException;

import java.io.Reader;

import java.sql.SQLException;

import java.util.List;

import com.ibatis.sqlmap.client.SqlMapClient;

public class IStudentDAOImpl implements IStudentDao {

private static SqlMapClient sqlMapClinet=null;

static {

Reader reader;

try {

reader = com.ibatis.common.resources.Resources.getResourceAsReader("com/it/SqlMapConfig.xml");

sqlMapClinet=com.ibatis.sqlmap.client.SqlMapClientBuilder.buildSqlMapClient(reader);

reader.close();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

public List<Note> queryAllN() {

// TODO Auto-generated method stub

List<Note> studentList =null;

try {

studentList=sqlMapClinet.queryForList("selectAllNote");

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return studentList;

}

public static void main(String[] args){

IStudentDao dao=new IStudentDAOImpl();

//dao.queryAllStudent();

System.out.println("OK");

//List<Student> myList=dao.queryAllStudent();

for(Note student :dao.queryAllStudent()){

System.out.println(student.getSname());

}

}

}
