相关疑难解决方法(0)

我有2个数据库(MySql和HSQLDB).我配置了2个数据源和2个EntityManagerFactory bean.我还可以配置2个对应的JpaTransactionManager bean.

但我不知道如何指定应该使用哪些来管理具体服务类的事务.我想@Transactional为此目的使用注释,但实际上我只能指定一个txManagers:

<tx:annotation-driven transaction-manager="manager"/>

这种情况的出路是什么？

我正在尝试配置Spring + Hibernate + JPA来处理两个数据库(MySQL和MSSQL).

我的datasource-context.xml:
