spring+hibernate+atomokis配置多数据源与事务

俺今天无法淡定了，先列个标题，把这几天烦人的东西都整理一遍，免得以后忘记鸟。AIX，我恨你。

   spring+hibernate配置多数据源并统一管理事物，首先确定的是必须使用JTA管理事物，在spring的HibernateTransactionManager类API中已经详细说明了两种transactionManager的不同，quote：JTA (usually through JtaTransactionManager) is necessary for accessing multiple transactional resources within the same transaction. The DataSource that Hibernate uses needs to be JTA-enabled in such a scenario (see container setup)。必须引用JTA，而且数据源必须是支持JTA的XAdatasource。quote百度百科：如果计划使用JTA来划分事务，你将需要一个实现了javax.sql.XADataSource，javax.sql.XAConnection和javax.sql.XAResource接口JDBC的驱动。好了，如果你还是坚持用HibernateTransactionManager的话，可以确定的是，事务不一定会回滚。
   现在在tomcat下用Atomikos实现JTA分布式事务管理，但是数据源只能用免费版的com.atomikos.jdbc.SimpleDataSourceBean，不能用收费版的com.atomikos.jdbc.AtomikosDataSourceBean。但是这个数据源和tomcat使用的时候关闭服务器时有可能引发内存溢出。tomcat6以上会强制解除那个实例，但是会提示你，因为tomcat已经强制移除了，所以除了日志也没啥关系，可以手动去掉那段监听
<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
attempts to log objects that have failed to be unregistered by webapps it hosts when they are stopped, and were forcibly unregistered by Tomcat.
   我想说这个数据源貌似使用起来问题蛮多的，日志文件有时候不自动删，内存老溢出，杂七杂八的，反正我现在还在改。程序也有问题哈，内存占用很变态，AIX服务器也很变态，总之都很变态，哥哥我也快变态了。总之想找一个好的实现了XADataSource的数据源，换个JBOSS去试试。
   然后复制一下spring的配置文件，如下
