Simple spring boot with jpa and camunda

I want to create a simple spring boot application which can save the data in the sql server and also perform camunda workflow. Can anyone help me with that?

I dont have camunda enterprise. I use community edition. I want to use rest api and do that.

Iam confused with runtime service, tasks and and all that stuff.

I understand the workflow and i know how to save the data in the database using spring boot but what should i do with List and what is all that.

I just want to create a simple spring boot and with jpa repository i want to save the data in the database and at the same time i want to use camunda workflow.

Do we need two seperate services for that. I dont know. Please help me.
