电话簿项目笔记-----------Model和DAO设计

阅读更多

（一）在Eclipse中创建Dynamic Web Project项目并导入Spring3.2和MyBatis3的Jar包，本项目截图如下：



（二）创建Model类

package com.model;

public class OwnerNumInfo {
	private int id;
	public String phoneNum;
	public String ownerName;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getPhoneNum() {
		return phoneNum;
	}

	public void setPhoneNum(String phoneNum) {
		this.phoneNum = phoneNum;
	}

	public String getOwnerName() {
		return ownerName;
	}

	public void setOwnerName(String ownerName) {
		this.ownerName = ownerName;
	}

	public String toString() {
		return "User[id=" + id + " , ownerName=" + ownerName + " , phoneNum=" + phoneNum + "]";
	}
}

（三）创建DAO接口

package com.dao;

import com.model.OwnerNumInfo;

public interface OwnerNumInfoDao {
	public OwnerNumInfo getOwnerNumInfoDao(OwnerNumInfo owner);
	public boolean addOwnerNumInfo(OwnerNumInfo owner);
	public boolean deleteOwnerNumInfo(int id);
	public boolean updateOwnerNumInfo(OwnerNumInfo owner);
}

（四）创建SQL语句映射文件
com.dao包下创建OwnerNumInfoDao.xml文件：

  

	
		SELECT * FROM ownernuminfo WHERE ownerName=#{ownerName} AND phoneNum=#{phoneNum}
	
	
		INSERT INTO ownernuminfo (id,ownerName,phoneNum) VALUES
		(#{id},#{ownerName},#{phoneNum})
	
	
		UPDATE ownernuminfo SET ownerName=#{ownerName},phoneNum=#{phoneNum} WHERE id=#{id}
	
	
		DELETE FROM ownernuminfo WHERE id=#{id}
	
  

（四）编写MyBatis配置文件
src目录下创建mybatis-config.xml文件：

（五）编写Spring配置文件
src目录下创建ApplicationContext.xml文件：

    
   
       
       
         org.gjt.mm.mysql.Driver  
       
       
         jdbc:mysql://localhost:3306/phonenumdb?useUnicode=true&characterEncoding=UTF-8  
        
       
       
         root  
       
       
         1234  
       
   
   
       
       
   
   
       
       
   
   

（六）编写测试类
src下创建test.java：

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.dao.OwnerNumInfoDao;
import com.model.OwnerNumInfo;
  
  public class test {
     
     /**
      * @param args
      */
     public static void main(String[] args) {
         ApplicationContext ctx=null;
         ctx=new ClassPathXmlApplicationContext("applicationContext.xml");
         OwnerNumInfoDao ownerNumInfoDao=(OwnerNumInfoDao) ctx.getBean("ownerNumInfoDao");
		OwnerNumInfo user=new OwnerNumInfo();
         //添加两条数据
         user.setId(1);
         user.setOwnerName("Jessica");
         user.setPhoneNum("123");
         ownerNumInfoDao.addOwnerNumInfo(user);
         user.setId(2);
         user.setOwnerName("Jessica2");
         user.setPhoneNum("123");
         ownerNumInfoDao.addOwnerNumInfo(user);
         System.out.println("添加成功");
         //查询数据
         user.setOwnerName("Jessica");
         user.setPhoneNum("123");
         System.out.println(ownerNumInfoDao.getOwnerNumInfoDao(user).toString());
         user.setOwnerName("Jessica2");
         user.setPhoneNum("123");
         System.out.println(ownerNumInfoDao.getOwnerNumInfoDao(user).toString());
         //修改数据
         user.setId(2);
         user.setPhoneNum("802");
         ownerNumInfoDao.updateOwnerNumInfo(user);
         System.out.println("修改成功");
         //删除数据
         ownerNumInfoDao.deleteOwnerNumInfo(1);
         System.out.println("删除成功");
         
     }
 
 }

（七）用到的Jar包
除了Spring3.2和Mybatis3之外，还需要用到mybatis-spring-1.2.1.jar
