1.5.12.RELEASE

Problem 1

When I used mongotemplate.find() to query data, it was very slow

Query query = new Query();
query.addCriteria(
    Criteria.where("serviceId").is("19")
);
List<DBObject> dbObjects = mongoTemplate.find(query, DBObject.class,collectionName);

  • Solution 3

  //You can also do this if you don't want to update the pom.xml
  BasicDBObject query = new BasicDBObject();
  query.put("serviceId", "19");
  DBCollection collection = mongoTemplate.getCollection(collectionName);
  DBCursor dbObjects = collection.find(query);
