Description:

Field srcDataSource in com.cku.assmt.dbimp.DBImporter required a single bean, but 2 were found:
    - srcDataSource: defined by method 'srcDataSource' in class path resource [com/cku/assmt/dbimp/DBConfig.class]
    - dstDataSource: defined by method 'dstDataSource' in class path resource [com/cku/assmt/dbimp/DBConfig.class]


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed
