first question so far. Have trouble to Autowire CassandraRepository. I have a multiple databases project. I want to use Postgres, Mongo and Cassandra. I got Mongo working, but Cassandra is a pain. I followed the Cassandra Spring Repository Guide Link (6. Repository) Link 2 (5. Repository), this guide isn't completed by Spring Guys, its just mentioned it's same as mongo but thats not true. I did the same as for mongo and stumbled about this error: Link with No qualifying Bean found to Autowire.
Found some google dev group mentioned the problem and solved it with some extra CassandraConfiguration Class. And now the Bean should be created, but i get a new Error, a better one i think.
org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.cassandra.core.CassandraAdminOperations]: Factory method 'cassandraTemplate' threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/cassandra/core/Cancellable
But at this time google didn't know the answer, spring boot is quite new... Have somebody tried to Autowire a CassandraRepository to an exisiting Spring-Boot Project? Could you help me?
Here are all my files:
