cumulocity-microservice-templates

Summary

Collection of templates / examples to give the developer a starting point how common features can be implemented in a Microservice by using Cumulocity's Microservice SDK for Java.

Templates & Examples

• basic

  • how to communicate with Cumulocity's REST API
  • how to implement REST endpoints, e.g. GET or POST
  • how to implement a scheduler
  • how to work with different contexts

• agent

  • how to create an agent representation for your Microservice
  • how to subscribe and receive configuration updates for your Microservice
  • how to write events
  • how to create measurement for microservice diagnostic (total, used and free memory)

• realtime

  • how to subscribe and listen for realtime notifications
  • how to get notified once a managedObject is being updated
  • how to get notified once a new measurement has been created for a device
  • how to receive operations and update their status

• secret

  • how to use tenant options
  • how to encrypt data and store it as a tenant option

• ehcache

  • how to use ehcache to implement a caching mechanism for External Ids and managedObjects

• multischeduler

  • how to start a separate scheduler thread for each tenant to run tasks in parallel.

• metrics

  • how to use the Micrometer Framework with custom metrics to enable fine grainular monitoring of a microservice and its custom business logic.

• interprocess communication - IPC

  • how to implement a interprocess communication between microservices based on REST. The solution is using a declarative REST client (Feign Spring Cloud) to call another microservice.

• context

  • how to use user & tenant context in microservices.
