本文介绍如何在Spring 2.5.8、Hibernate 3.2和Proxool 0.9.1环境下配置JTA事务管理。具体包括applicationContext-core.xml中的数据源、事务管理器和SessionFactory配置，以及jdbc.properties和proxool.xml文件的详细设置。

最近配置公司新项目的开发环境，由于个人感觉proxool的数据源比较好用，但是发现网上没有相关方面配置jta的配置代码

于是个人总结后，记录了以下配置方式

以下配置的各开源版本

spring version 2.5.8

hibernate version 3.2

proxool version 0.9.1

这三个的版本比较关键，如果有问题，可能会发生冲突，关于jotm的版本比较宽松，这里不作特定要求

applicationContext-core.xml数据源配置：

jdbc.properties配置：
