**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
