It looks like if you need multiple data sources, the Spring Boot magic runs out, and you have to take over the configuration manually.

In my case, I had to modify the EnableAutoConfiguration to take over the data source and transaction manager configuration myself:

@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class,DataSourceTransactionManagerAutoConfiguration.class}) 

It looks like the Spring Boot magic ran out at the point I had to use multiple data sources...
