java - Apache Ignite mongo configuration using spring -

i introducing apache ignite in our application cache system computation. have configured spring application using following configuration class.

@configuration @enablecaching public class igniteconfig {      @value("${ignite.config.path}")     private string ignitepath;      @bean(name="cachemanager")     public springcachemanager cachemanager(){         springcachemanager springcachemanager = new springcachemanager();         springcachemanager.setconfigurationpath(ignitepath);         return springcachemanager;     } } 

using like

@override @cacheable("cache1") public list<channel>  getallchannels(){     list<channel> list = new arraylist<channel>();     channel c1 = new channel("1",1);     channel c2 = new channel("2",2);     channel c3 = new channel("3",3);     channel c4 = new channel("4",4);     list.add(c1);     list.add(c2);     list.add(c3);     list.add(c4);     return list; } 

now want add write-through , read-through feature. not find documentation connect ignite mongo.

the idea not talk db directly through ignite using write behind feature.

edit-----------------------

as suggested implemented

public class channelcachestore extends cachestoreadapter<long, channel> implements serializable {      @override     public channel load(long key) throws cacheloaderexception {         return getchanneldao().findone(channel.mongochannelcode, key);     }      @override     public void write(cache.entry<? extends long, ? extends channel> entry) throws cachewriterexception {         getchanneldao().save(entry.getvalue());     }      @override     public void delete(object key) throws cachewriterexception {         throw new unsupportedoperationexception("delete not supported");     }      private channeldao getchanneldao(){         return springcontextutil.getapplicationcontext().getbean(channeldao.class);     } } 

and added cachestore cache configuration below :

<property name="cacheconfiguration">         <list>             <bean class="org.apache.ignite.configuration.cacheconfiguration">                 <property name="name" value="channelcache"/>                 <property name="cachemode" value="partitioned"/>                 <property name="atomicitymode" value="atomic"/>                 <property name="backups" value="1"/>                 <property name="readthrough" value="true"/>                 <!-- sets flag indicating whether write database enabled. -->                 <property name="writethrough" value="true"/>                 <!-- enable database batching. -->                  <!-- sets flag indicating whether write-behind enabled. -->                 <property name="writebehindenabled" value="true"/>                 <property name="cachestorefactory">                     <bean class="javax.cache.configuration.factorybuilder$singletonfactory">                         <constructor-arg>                             <bean class="in.per.amt.ignite.cache.channelcachestore"></bean>                         </constructor-arg>                     </bean>                 </property>             </bean>         </list>     </property> 

but getting class cast exception

java.lang.classcastexception: org.springframework.cache.interceptor.simplekey cannot cast java.lang.long     @ in.per.amt.ignite.cache.channelcachestore.load(channelcachestore.java:19) 

you can have kind of backing database implementing cachestore interface:
