Cassandra session null at runtime -


i have following problem: want make list of cassandra templates starting list of sessions. problem @ runtime session oject null. code use following:

import java.util.arraylist; import java.util.list;  import org.springframework.beans.factory.annotation.autowired; import org.springframework.beans.factory.annotation.qualifier; import org.springframework.data.cassandra.config.cassandraclusterfactorybean; import org.springframework.data.cassandra.config.cassandrasessionfactorybean; import org.springframework.data.cassandra.config.schemaaction; import org.springframework.data.cassandra.convert.cassandraconverter; import org.springframework.data.cassandra.core.cassandraoperations; import org.springframework.data.cassandra.core.cassandratemplate; import org.springframework.stereotype.component;  @component public class keyspacesession {      @autowired     @qualifier("cluster")     cassandraclusterfactorybean cluster;      @autowired     @qualifier("converter")     cassandraconverter converter;       public list<cassandraoperations> gettemplates(){         list<cassandraoperations> listoftemplates = new arraylist<>();         for(cassandrakeyspaces keyspace : cassandrakeyspaces.values()){             cassandrasessionfactorybean session = new cassandrasessionfactorybean();             session.setcluster(cluster.getobject());             session.setkeyspacename(keyspace.getkeyspace());             session.setconverter(converter);             session.setschemaaction(schemaaction.create_if_not_exists);              cassandraoperations op = new cassandratemplate(session.getobject());             listoftemplates.add(op);         }         return listoftemplates;     }  }

i following answer server:

{   "timestamp": 1505204641753,   "status": 500,   "error": "internal server error",   "exception": "java.lang.illegalargumentexception",   "message": "session must not null",   "path": "/getuser/10/pl" }

cassandrasessionfactorybean requires initialization after you've set properties. call cassandrasessionfactorybean.afterpropertiesset() before obtaining session. need clean sessions on application shutdown.

ideally, register beandefinitions each session , cassandraoperations bean want create.
