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());

                           

                   }

         }

}
