Traditional solutions for distributed transaction jta + atomikos registered with a global transaction, the transaction will be registered to Atomikos to go to achieve a global transaction, properties file:
Custom attribute class, and read register to Atomikos form global transaction class

After registering to Atomikos, the obligation would not specify the annotation layer to enable transaction manager of the database transaction points like that, only with the @Transactional to comment, as it has been registered as a global transaction, and
Remember to add on startup class
@EnableConfigurationProperties(value = { DBConfig1.class, DBConfig2.class })
It opens and reads the configuration file.
So that we can solve problems between different transaction management services.
This program is not recommended for micro-services, because there is no compensation mechanism, the performance is not very good (electronic business systems generally do not use this method, generally used for conventional projects). Small items can be used in this way, and you can get to the data source.
