Spring配置一个事务中多个数据源
（个人观点）在一个事务中包含多个数据源的更新操作时，需要JTA的支持，通常JTA的支持是由J2EE容器提供的（WAS，Weblogic...），也有单独实现JTA的第3方jar。
Spring提供的是jotm和xapool，但在配置过程中遇到了问题，使用org.enhydra.jdbc.standard.StandardXADataSource做数据源时，它的shutdown方法是带参数的
<bean id="innerMysqlDataSource" class="org.enhydra.jdbc.standard.StandardXADataSource" destroy-method="shutdown">...</bean>
xapool的文档做的不好就没有继续，又找了另一个，AtomikosTransactionsEssentials（支持JMS和JDBC作为数据源）。

xaDataSourceClassName是设置javax.sql.XADataSource（使用DB的驱动提供），其中xaProperties是Map类型的，通过反射设置javax.sql.XADataSource的属性。例子中使用的是DB2。
