Spring Boot with multiple database using hibernate and JpaRepository -

how implement multiple database configurations in spring boot ??? how create spring boot mvc application 2 different databases using hibernate ???

application.properties(db1=core,db2=staging)

server.port=8772   spring.core.driverclassname=com.mysql.jdbc.driver spring.core.url=jdbc:mysql://ip:port/coredb spring.core.username=uname spring.core.password=pwd   spring.staging.driverclassname=com.mysql.jdbc.driver spring.staging.url=jdbc:mysql://ip:port/stagingdb spring.staging.username=uname spring.staging.password=pwd 

repository :

public interface istagingentitydao  extends    jparepository<stagingemployee, integer>{         query("select e stagingemployee e")       public list<stagingemployee> getentitydata();  } 

dbconfig :

public class dbconfig {      @bean(name="stagingdatasource")     @primary     @configurationproperties(prefix="spring.staging")     public datasource stagingdatasource()     {         return datasourcebuilder.create().build();     }      @bean(name="coredatasource")     @configurationproperties(prefix="spring.core")     public datasource coredatasource()     {         return datasourcebuilder.create().build();     } } 

requirement :

i want copy data 1 db consider employee entity want copy data db1 db2 have done far have create controller(@restcontroller) , service , repository data db 1 , push in db2 calling respective service in single spring boot app itself.

exception : cannot determine embedded database driver class database type none. if want embedded database please put supported 1 on classpath.

whats missing in above configurations ????

i think can find usefull

http://docs.spring.io/spring-boot/docs/current-snapshot/reference/htmlsingle/#howto-two-datasources

it shows how define multiple datasources & assign 1 of them primary.

here rather full example, contains distributes transactions - if need it.

what need create 2 configuration classes, separate model/repository packages etc make config easy.

also, in above example, creates data sources manually. can avoid using method on spring doc, @configurationproperties annotation. here example of this:
