Interface MongoOperations

All Superinterfaces:
ExecutableAggregationOperation, ExecutableFindOperation, ExecutableInsertOperation, ExecutableMapReduceOperation, ExecutableRemoveOperation, ExecutableUpdateOperation, FluentMongoOperations
All Known Implementing Classes:
MongoTemplate

public interface MongoOperations extends FluentMongoOperations
Interface that specifies a basic set of MongoDB operations. Implemented by MongoTemplate. Not often used but a useful option for extensibility and testability (as it can be easily mocked, stubbed, or be the target of a JDK proxy).
NOTE: Some operations cannot be executed within a MongoDB transaction. Please refer to the MongoDB specific documentation to learn more about Multi Document Transactions.

    • geoNear

      @Deprecated <T> GeoResults<T> geoNear(NearQuery near, Class<T> entityClass)
      Deprecated.
      since 2.2. The eval command has been removed in MongoDB Server 4.2.0. Use Aggregations with Aggregation.geoNear(NearQuery, String) instead.
      Returns GeoResults for all entities matching the given NearQuery. Will consider entity mapping information to determine the collection the query is ran against. Note, that MongoDB limits the number of results by default. Make sure to add an explicit limit to the NearQuery if you expect a particular number of results.

      MongoDB 4.2 has removed the geoNear command. This method uses since version 2.2 aggregations and the $geoNear aggregation command to emulate geoNear command functionality. We recommend using aggregations directly:

       TypedAggregation<T> geoNear = TypedAggregation.newAggregation(entityClass, Aggregation.geoNear(near, "dis"))
                      .withOptions(AggregationOptions.builder().collation(near.getCollation()).build());
       AggregationResults<Document> results = aggregate(geoNear, Document.class);
       
      Parameters:
      near - must not be null.
      entityClass - must not be null.
      Returns:

      default long exactCount(Query query, Class<?> entityClass)
      Returns the number of documents for the given Query by querying the collection of the given entity class.
      NOTE: Query offset and limit can have direct influence on the resulting number of documents found as those values are passed on to the server and potentially limit the range and order within which the server performs the count operation. Use an unpaged query to count all matches.
      This method uses an aggregation execution even for empty queries which may have an impact on performance, but guarantees shard, session and transaction compliance. In case an inaccurate count satisfies the applications needs use estimatedCount(Class) for empty queries instead.
      Parameters:
      query - the Query class that specifies the criteria used to find documents. Must not be null.
      entityClass - class that determines the collection to use. Must not be null.
      Returns:
      the count of matching documents.
      Throws:
      MappingException - if the collection name cannot be derived from the given type.

      If your object has an Id property which holds a null value, 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.
