Introduction This project demonstrates how to implement a Spring Batch Job as a Spring Rest service. Introduction to Bulk and Batch API The terms bulk and batch operation are often used interchangeably. Here we looked at an In this article, we will explore how to implement batch operation that reads from REST resources with Spring Batch through JsonItemReader. Tested on OpenJDK 8 and 11.
