Answer 1

我为这个问题专门写了一个测试用例：

看下面的几个文件：
可能贴的顺序上有点问题，楼主可以自己整理一下：

(1) applicationContext.xml

---------------------

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "">

<beans>
<!-- 引入参数配置文件 -->
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

</bean>

<!-- 事务管理器 -->

<bean class="com.spring.demo.manager.Hibernate_BookManager">
<property name="dao">
<ref bean="hibernate_BookDao"/>
</property>
</bean>
</property>
</bean>

</beans>

---------------------

(2) jdbc.properties
## 这个事连接mysql数据库的具体参数配置，
## 楼主要根据自己的数据来配置，不可直接使用
---------------------

jdbc.driverClass=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/springdemo?useUnicode=true&characterEncoding=utf-8

jdbc.user=root
jdbc.password=root
jdbc.initialPoolSize=1
jdbc.minPoolSize=1
jdbc.maxPoolSize=10

---------------------

说明：applicationContext.xml 应用了jdbc.properties文件

，我自己测试，没有问题，而且是spring配置式事务的。

需要JAR包

spring.jar
c3p0.jar
mysql.jar
cglib.jar
asm.jar
antlr.jar
hibernate3.jar
jta.jar
dom4j.jar
commons-collections.jar
commons-logging.jar

Hibernate_BookDao.java

--------------

package com.spring.demo.dao;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.spring.demo.bean.Book;

/**
*
* @author wangyudong

*/
public class Hibernate_BookDao extends HibernateDaoSupport {

/**
* 添加一本书
* @param book
*/
public void insertBook(Book book){
this.getHibernateTemplate().save(book);
}

/**
* 修改一本书
* @param book
*/
public void updateBook(Book book){
this.getHibernateTemplate().update(book);
}

/**
* 根据ID来删除一本书
* @param id
*/
public void deleteBook(Integer id){
Book book = new Book();
book.setId(id);
this.getHibernateTemplate().delete(book);
}

/**
* 根据ID来查询书对象
* @param id

*/
public Book selectBookById(Integer id){
String hql = "from Book b where b.id=?";
Object[] params = new Object[];
List list = this.getHibernateTemplate().find(hql, params );

if(list!=null && list.size()>0){
return (Book)list.get(0);
}
return null ;
}

/**

*/
public List selectBookByName(String name){

String hql = "from Book b where b.name like ?";
Object[] params = new Object[];
return this.getHibernateTemplate().find(hql, params);
}

}

(2) Hibernate_BookManager.java

---------------

package com.spring.demo.manager;

import java.util.List;

import com.spring.demo.bean.Book;
import com.spring.demo.dao.Hibernate_BookDao;

public class Hibernate_BookManager {

private Hibernate_BookDao dao ;

/**
* 批量添加书本，如果列表长度超过3，就抛出异常

*/
public void insertBooks(List books){

for(int i=0 ; i<books.size() ;i++){
if(i>2){
throw new RuntimeException("中断事务异常,当列表长度大于3的时候故意抛出，看看事务是否回滚");
}
Book book = (Book)books.get(i);
dao.insertBook(book);
}
}

/**

public void insertBook(Book book){
this.dao.insertBook(book);
}

/**

public void updateBook(Book book){
this.dao.updateBook(book);
}

/**

public void deleteBook(Integer id){
this.dao.deleteBook(id);
}

/**

public Book selectBookById(Integer id){
return this.dao.selectBookById(id);
}

/**
* 根据书名来查询相关书记录列表
* @param name

*/
public List selectBookByName(String name){
return this.dao.selectBookByName(name);
}

// getter and setter //
public Hibernate_BookDao getDao() {
return dao;
}

public void setDao(Hibernate_BookDao dao) {
this.dao = dao;
}
}

（3）Book.java

--------------
package com.spring.demo.bean;

import java.io.Serializable;

/*

DROP TABLE IF EXISTS book ;

CREATE TABLE book(
id int(11) NOT NULL auto_increment COMMENT 'primary key',
name varchar(60) default NULL COMMENT 'book name',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT='my book table';

*/

public class Book implements Serializable {

public Book(){}

public Book(String name){
this.name = name;
}

/**
* ID
*/
private Integer id ;

/**
* 书名
*/
private String name ;

// getter and setter
public Integer getId() {
return id;
}

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

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

}
--------------

（4）Book.hbm.xml
---------------
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"">

<hibernate-mapping>
<class name="com.spring.demo.bean.Book" table="BOOK" >
<id name="id" type="integer" length="11">
<column name="id" />
<generator class="identity" />
</id>

<property name="name" column="NAME" type="string" length="60" ></property>

</class>
</hibernate-mapping>
---------------

#mysql的造表语句，指定了数据库springdemo#
---------------------
MYSQL 的BOOK 表创建语句

CREATE DATABASE IF NOT EXISTS springdemo;

USE springdemo;

DROP TABLE IF EXISTS book ;

CREATE TABLE book(
id int(11) NOT NULL auto_increment COMMENT 'primary key',
name varchar(60) default NULL COMMENT 'book name',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT='my book table';

---------------------

下面是我的测试方法：
===========

package com.spring.demo;

import java.util.ArrayList;
import java.util.List;

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

import com.spring.demo.bean.Book;
import com.spring.demo.manager.Hibernate_BookManager;

public class HibernateDemo {

/**
* @param args
*/
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml") ;

Hibernate_BookManager manager = (Hibernate_BookManager)context.getBean("hibernate_BookManager");

List books = new ArrayList();

books.add(new Book("book_01"));
books.add(new Book("book_02"));
books.add(new Book("book_03"));
books.add(new Book("book_04"));

manager.insertBooks(books);

System.out.println("OK");

}

}

确信是调通的，
==================

看在我专门为回答这个问题写了这个测试用例，
给个高分？

无非就是listener事件＋jdbc操作数据库，楼主网上搜下吧一大把。要给你程序是没有的
