spring + hibernate+ C3P0+MYSQL 配置
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
---------------------

</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

（3）Book.java

public class Book implements Serializable {
public Book(){}
public Book(String name){
this.name = name;
}
/**
* ID
*/
private Integer id ;
/**

private String name ;

public Integer getId() {

（4）Book.hbm.xml
---------------

#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");
}
}
