computer例子用spring+hibernarte做的改进工作

1。多出的配置文件

<?xml version="1.0" encoding="GBK"?><!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN/EN" "http://www.springframework.org/dtd/spring-beans.dtd"><beans><bean id="datasource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName">  <value>com.mysql.jdbc.Driver</value> </property>  <property name="url">  <value>jdbc:mysql://localhost:3306/yay</value> </property>  <property name="username">  <value>root</value> </property>  <property name="password">  <value>qwe123</value> </property></bean>

<!-- 从单纯的Hibernate转到这里得Spring+Hibernate，原来得bean都不用修改 这里只是需要增加这个部分合下面的两个bean定义--><bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean" destroy-method="close"> <property name="dataSource">  <ref bean="datasource"/> </property>   <property name="mappingResources">  <list>   <value>computer.hbm.xml</value>  </list> </property>   <property name="hibernateProperties">  <props>   <prop key="hibernate.dialect">    org.hibernate.dialect.MySQLDialect   </prop>  </props> </property></bean>  <bean id="computerDao" class="com.yinbodotcc.springHibernate.transaction.ComputerDao"> <property name="sessionFactory">  <ref bean="sessionFactory"/> </property></bean>

</beans>

 

2。测试文件

package com.yinbodotcc.springHibernate;

import org.springframework.context.ApplicationContext;import org.springframework.context.support.FileSystemXmlApplicationContext;

public class Test{  public static void main(String agrs[]) {  //这里和上一个例子用法就不一样了，这里是因为用了Spring+Hibernate  ApplicationContext context=new FileSystemXmlApplicationContext("dbcp-spring-config1.xml");  IComputerDao ic=(ComputerDao)context.getBean("computerDao");    Computer c=new Computer();  c.setId(8);//注意设置为auto_increment则这里的设置不起作用  c.setUser("yay");  c.setType("notepad");    ic.addComputer(c);    c=ic.findComputer(2);  if(c!=null)  System.out.println("发现得电脑使用者是： "+c.getUser()); }

}
