```
public <T> T save(T objectToSave,
                  String collectionName)
```
    Description copied from interface: MongoOperations
    
    Save the object to the specified collection. This will perform an insert if the object is not already present, that is an 'upsert'.
    The object is converted to the MongoDB native representation using an instance of MongoConverter. Unless configured otherwise, an instance of MappingMongoConverter will be used.
    If you object has an "Id' property, it will be set with the generated Id from MongoDB. If your Id property is a String then MongoDB ObjectId will be used to populate that string. Otherwise, the conversion from ObjectId to your property type will be handled by Spring's BeanWrapper class that leverages Type Conversion API. See Spring's Type Conversion" for more details.

```
    Map the results of an ad-hoc query on the default MongoDB collection to a List of the specified type. The object is converted from the MongoDB native representation using an instance of MongoConverter. The query document is specified as a standard Document and so is the fields specification.
    
    Parameters:
    
    collectionName - name of the collection to retrieve the objects from.
    
    query - the query document that specifies the criteria used to find a record.
    
    fields - the document that specifies the fields to be returned.
    
    entityClass - the parameterized type of the returned list.
    
    preparer - allows for customization of the DBCursor used when iterating over the result set, (apply limits, skips and so on).
    
    Returns:
    
    the List of converted objects.

```
    Convert given CollectionOptions to a document and take the domain type information into account when creating a mapped schema for validation.
    This method calls convertToDocument(CollectionOptions) for backwards compatibility and potentially overwrites the validator with the mapped validator document. In the long run convertToDocument(CollectionOptions) will be removed so that this one becomes the only source of truth.
    
    Parameters:
    
    collectionOptions - can be null.
    
    targetType - must not be null. Use Object type instead.
    
    Returns:
    
    never null.

```
    Deprecated. since 2.1 in favor of convertToDocument(CollectionOptions, Class).
    
    Parameters:
    
    collectionOptions - can be null.

```
    Map the results of an ad-hoc query on the default MongoDB collection to an object using the template's converter. The first document that matches the query is returned and also removed from the collection in the database.
    The query document is specified as a standard Document and so is the fields specification.
    
    Parameters:
    
    collectionName - name of the collection to retrieve the objects from
    
    query - the query document that specifies the criteria used to find a record
    
    entityClass - the parameterized type of the returned list.
