Distributed transaction processing method and system for multi-data sources

The invention provides a distributed transaction processing method and system for multi-data sources. A transaction definition module conducts processing based on the standard of an SG-UAP extension module and in accordance with an OSGI framework, the definition of distributed transactions of different data sources is achieved for call and configuration by transaction developers, and thus the unification and configurability of development of distributed transactions are achieved; a transaction coordinator analyzes configuration files of the distributed transactions defined by the transaction definition module so that the unification and coordination of all the distributed transactions in a whole service system can be achieved, and transaction processing tasks of specified data sources are unified and coordinated and then distributed to different transaction managers; the transaction managers send the received distributed transactions to corresponding resource managers respectively; the resource managers condu
