org.springframework.data.mongodb.core.ReactiveMongoTemplate

All Implemented Interfaces:: Aware, ApplicationContextAware, ReactiveAggregationOperation, ReactiveChangeStreamOperation, ReactiveFindOperation, ReactiveFluentMongoOperations, ReactiveInsertOperation, ReactiveMapReduceOperation, ReactiveMongoOperations, ReactiveRemoveOperation, ReactiveUpdateOperation

public class ReactiveMongoTemplate extends Object implements ReactiveMongoOperations, ApplicationContextAware

Primary implementation of ReactiveMongoOperations. It simplifies the use of Reactive MongoDB usage and helps to avoid common errors. It executes core MongoDB workflow, leaving application code to provide Document and extract results. This class executes BSON queries or updates, initiating iteration over FindPublisher and catching MongoDB exceptions and translating them to the generic, more informative exception hierarchy defined in the org.springframework.dao package. Can be used within a service implementation via direct instantiation with a ReactiveMongoDatabaseFactory reference, or get prepared in an application context and given to services as bean reference.

Note: The ReactiveMongoDatabaseFactory should always be configured as a bean in the application context, in the first case given to the service directly, in the second case to the prepared template.

`ReadPreference` and `ReadConcern`

ReadPreference and ReadConcern are generally considered from Query and AggregationOptions objects for the action to be executed on a particular MongoCollection.

You can also set the default ReadPreference on the template level to generally apply a ReadPreference.

  The object is converted to the MongoDB native representation using an instance of .
  If your 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.
  Insert is used to initially store the object into the database. To update an existing object use the save method.
  A potential Version the property will be auto incremented. The operation raises an error in case the document has been modified in between.
