Holon platform examples: MongoDB Datastore

This is one of the Holon Platform example projects.

This example shows how to deal with the basic operations of the Datastore API, using a Mongo Datastore implementation.

Spring Boot is used for Datastore configuration, enabled by using the holon-starter-mongo-datastore starter. See the example pom.

Topics

This example addresses the following topics:

• Automatic setup of a MongoDB Datastore using the Holon Platform Spring Boot integration
• Management of a simple data entity using the Datastore API (create, update, delete, query)

Example structure

The Product class represents the property model for a simple product document schema.

Please note:

• The TARGET field of the Product class is the definition of a named DataTarget which refers to the products collection name to be used with Datastore operations.

• The TestDatastore class is a JUnit test class to show how to use the Datastore API to create, update delete and query the products, relying on the PropertyBox type to handle the property values.

Run this example

Run the unit test class using mvn test or your favorite IDE command.
