小知识插曲:

在MyEclipse中如何将源码配置到相关的jar包:

Jar包---propreties------JavaSourceAttachment------External File ----fileof source.jar

1、 编写jdbc.properties配置jdbc的相关参数

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/sms
jdbc.username=root
jdbc.password=root

2、编写Javabean和映射文件:

JavaBean:
package com.spring.model;
public class User {
	private int id;
	private String name;
	
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
}

映射文件:

<?xml version="1.0"?>  
<!DOCTYPE hibernate-mapping PUBLIC   
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"  
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">  
<hibernate-mapping   
    package="com.spring.model">  
    <class name="User">  
        <id name="id">  
            <generator class="native"/>  
        </id>  
        <property name="name" />
    </class>  
      
</hibernate-mapping>

3、 配置spring容器初始化sessionFactory

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
           http://www.springframework.org/schema/context
           http://www.springframework.org/schema/context/spring-context-2.5.xsd
           http://www.springframework.org/schema/aop
           http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
	<context:annotation-config />
	<!-- 配置容器资源扫描的包 -->
	<context:component-scan base-package="com.spring" />
	<!-- 将前面类写入容器 -->
	<bean id="logInterceptor" class="com.spring.aop.LogInterceptor" />

	<!--
		配置数据源 <bean id="myDataSource"
		class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close"> <property name="driverClassName"
		value="com.mysql.jdbc.Driver"/> <property name="url"
		value="jdbc:mysql://localhost:3306/sms"/> <property name="username"
		value="root"/> <property name="password" value="root"/> </bean>
	-->

	
	<!-- placeholder 占位符 -->
	<bean
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<value>classpath:jdbc.properties</value>
		</property>
	</bean>
	<!-- 配置dataSource -->
	<bean id="dataSource" destroy-method="close"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName" value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />
	</bean>

	<!-- 将配置好的dataSource注入到SessionFactory中-->
	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="mappingResources">
      <list>
        <value>com/spring/model/user.hbm.xml</value>
      </list>
    </property>
    <property name="hibernateProperties">
      <value>
        hibernate.dialect=org.hibernate.dialect.MySQLDialect
        hibernate.show_sql=true
        hibernate.hbm2ddl.auto=create
      </value>
    </property>
  </bean>
</beans>

4、编写测试类:

package com.spring.test;

import org.junit.Test;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.spring.service.UserService;

public class SpringTest {

	@Test
	public void test01() {
		BeanFactory applicationContext = new ClassPathXmlApplicationContext(
				"beans.xml");
		UserService user = (UserService) applicationContext.getBean("userService");
		user.save();
	}
}

需要的hibernate Jar包:

需要的spring jar包:

此外还需要Junit、数据库连接驱动、J2ee的jar包
