Mongodb find query with java

MongoOperation mo = (MongoOperations)mongoTemplate;

MongoCollection<Document> coll = mo.getCollection("collectioName");

BasicDBObject findquery = new BasicDBObject();

findquery.put("name", "someoneName");

 

FindIterable<Document> ret = coll.find(findquery);

for(Document dbObject:ret){

System.out.println(dbObject.toJson());

}

 

여기서 콜렉션을 가져올때 <Document>를 빼고 find해서 가져오면

can not cast to bson object인가 exception이 뜨던데... Document를 빼게되면 ret 받을때도 Document빼고 bson으로 받아야 되는거 같다.
