I am working on spring data mongodb project and i have a complex object that not able to map using metadata mapping because it has composite key. I wrote a custom converter and trying to use mongoTemplate.find() but its not triggering the custom converter mapping.

Configuration:

Code:
<!-- MongoDB Factory -->
	<mongo:mongo id="mongo" host="${mongo.host.name}" port="${mongo.host.port}">
		<mongo:options connections-per-host="100"
			threads-allowed-to-block-for-connection-multiplier="100"
			connect-timeout="30000" max-wait-time="10000" auto-connect-retry="true"
			socket-keep-alive="false" socket-timeout="100000" slave-ok="false"
			write-number="1" write-timeout="0" write-fsync="true" />
	</mongo:mongo>
	<mongo:db-factory dbname="${mongo.db.name}" password="${mongo.password}"
		username="${mongo.user.name}" mongo-ref="mongo" />
	<!-- Mongo custom converters -->
	<mongo:mapping-converter base-package="com.ranker.app.mongo.domain">
		<mongo:custom-converters
			base-package="com.ranker.app.mongo.customconverter.agglist.converter" />
	</mongo:mapping-converter> 
	<!-- Offers convenience methods and automatic mapping between MongoDB JSON 
		documents and your domain classes. -->
	<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
		<constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
		<constructor-arg name="mongoConverter" ref="mappingConverter" />
	</bean>

converters:

Code:
package com.ranker.app.mongo.customconverter.agglist.converter;

import java.util.Date;

import org.springframework.core.convert.converter.Converter;

import com.mongodb.DBObject;
import com.ranker.app.mongo.domain.list.ListAggView;
import com.ranker.app.mongo.domain.list.ListViewId;
import com.ranker.app.mongo.domain.list.View;

public class ListAggViewReadConverter implements Converter<DBObject, ListAggView>
{

    public ListAggView convert(DBObject source)
    {
        ListAggView listAggView = new ListAggView();
        View view = new View();
        ListViewId listViewId = new ListViewId();
        listViewId.setEventDate((Date) source.get("_id.d"));
        listViewId.setLid((Integer) source.get("_id.lid"));
        view.setCount((Integer) source.get("value.count"));
        view.setMean((Integer) source.get("value.mean"));
        view.setEventDate((Date) source.get("value.eventdate"));
        view.setTotal((Integer) source.get("value.total"));
        listAggView.setView(view);
        listAggView.setListViewId(listViewId);
        return listAggView;
    }

}

package com.ranker.app.mongo.customconverter.agglist.converter;

import org.springframework.core.convert.converter.Converter;

import com.mongodb.BasicDBObject;
import com.mongodb.DBObject;
import com.ranker.app.mongo.domain.list.ListAggView;

public class ListAggViewWriteConverter implements Converter<ListAggView, DBObject>
{
    public DBObject convert(ListAggView source)
    {
        DBObject dbo = new BasicDBObject();
        dbo.put("_id.lid", source.getListViewId().getLid());
        dbo.put("_id.d", source.getListViewId().getEventDate());
        dbo.put("value.count", source.getView().getCount());
        dbo.put("value.total", source.getView().getTotal());
        dbo.put("value.mean", source.getView().getMean());
        dbo.put("value.eventdate", source.getView().getEventDate());
        return dbo;
    }
}

Service class:

Code:
@Service
public class MDListViewAggService
{
    @Autowired
    MongoTemplate m_mongoTemplate;

    public List<ListAggView> getAggView(Integer listId)
    {
        Query query = new Query();
        Criteria criteria = new Criteria().andOperator(Criteria.where("_id.lid").is(listId));
        query.addCriteria(criteria);
        List<ListAggView> listAggViews = m_mongoTemplate.find(query, ListAggView.class, "stats.daily");
        return listAggViews;
    }
}
Using spring data 1.1.0 version,

If anybody find what am doing wrong here, please let me know

thank you in advance
