In this post, we'll learn how to create a batch processing system in Spring Boot. We'll cover the following topics:
Batch processing is the execution of a series of jobs in a predetermined, sequential order. A batch job is a unit of work that is typically executed as a single process. Batch jobs are typically used for long-running, resource-intensive tasks that are not suitable for real-time execution, such as data ETL (extract, transform, and load), data cleansing, or data aggregation.
Spring Boot is a popular framework for building Java applications. It is designed to simplify the development and deployment of Spring-based applications. Spring Boot is a great choice for building batch processing systems because it provides a simple and straightforward way to configure and execute batch jobs.
To set up a Spring Boot project for batch processing, we need to add the following dependencies to our project:
We'll create a simple batch job that reads data from a CSV file and writes it to a MySQL database. The job will have the following steps:
To run our batch job, we'll use the Spring Boot Command Line Interface (CLI). The CLI is a tool that allows us to run Spring Boot applications from the command line.
