电话簿项目笔记-----------Model和DAO设计

（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：

<?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"   
  "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.dao.OwnerNumInfoDao">
	<select id="getOwnerNumInfoDao" parameterType="com.model.OwnerNumInfo"
		resultType="com.model.OwnerNumInfo">
		SELECT * FROM ownernuminfo WHERE ownerName=#{ownerName} AND phoneNum=#{phoneNum}
	</select>
	<insert id="addOwnerNumInfo" parameterType="com.model.OwnerNumInfo"
		flushCache="true">
		INSERT INTO ownernuminfo (id,ownerName,phoneNum) VALUES
		(#{id},#{ownerName},#{phoneNum})
	</insert>
	<update id="updateOwnerNumInfo" parameterType="com.model.OwnerNumInfo">
		UPDATE ownernuminfo SET ownerName=#{ownerName},phoneNum=#{phoneNum} WHERE id=#{id}
	</update>
	<delete id="deleteOwnerNumInfo" parameterType="int">
		DELETE FROM ownernuminfo WHERE id=#{id}
	</delete>
</mapper>  

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

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC  
    "-//mybatis.org//DTD Config 3.0//EN"  
     "http://mybatis.org/dtd/mybatis-3-config.dtd">  
 <configuration>  
     <mappers>  
         <mapper resource="com/dao/OwnerNumInfoDao.xml"/>  
     </mappers>  
 </configuration>  

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

<?xml version="1.0" encoding="UTF-8"?>
  <beans  
      xmlns="http://www.springframework.org/schema/beans"  
      xmlns:tx="http://www.springframework.org/schema/tx"  
      xmlns:p="http://www.springframework.org/schema/p"  
      xmlns:aop="http://www.springframework.org/schema/aop"   
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
      xsi:schemaLocation="http://www.springframework.org/schema/beans   
      http://www.springframework.org/schema/beans/spring-beans-3.0.xsd   
     http://www.springframework.org/schema/tx   
     http://www.springframework.org/schema/tx/spring-tx-3.0.xsd   
     http://www.springframework.org/schema/aop    
     http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">  
 <!-- 配置数据源-->  
     <bean id="jdbcDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">  
     <property name="driverClassName">  
         <value>org.gjt.mm.mysql.Driver</value>  
     </property>  
     <property name="url">  
         <value>jdbc:mysql://localhost:3306/phonenumdb?useUnicode=true&amp;characterEncoding=UTF-8</value>  
        <!--springmybaitis是我的数据库  -->
     </property>  
     <property name="username">  
         <value>root</value>  
     </property>  
     <property name="password">  
         <value>1234</value>  
     </property>  
 </bean>  
 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
     <property name="dataSource" ref="jdbcDataSource" />  
     <property name="configLocation" value="classpath:mybatis-config.xml"></property>  
 </bean>  
 <bean id="ownerNumInfoDao" class="org.mybatis.spring.mapper.MapperFactoryBean">  
     <property name="mapperInterface" value="com.dao.OwnerNumInfoDao"></property>  
     <property name="sqlSessionFactory" ref="sqlSessionFactory"></property>  
 </bean>  
 </beans>  

（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
