Building a Batch Application with Spring Batch
In this course, we will introduce the fundamental concepts of batch processing and cover the main features of Spring Batch. You will build a complete batch application with Spring Batch and Spring Boot and learn how to implement robust and fault-tolerant batch solutions.
What you'll learn
Streamline Your Daily Operations
Spring Batch is a lightweight, comprehensive batch framework designed to enable the development of robust batch applications vital for the daily operations of enterprise systems. In this course, you'll get a solid introduction to Spring Batch and learn how to use it with Spring Boot. For your course project, our experts will guide you through building and running a fully functional batch application that generates billing reports for a fictional cell phone company.
You'll learn to:
- Understand the basics of batch processing with Spring Batch
- Identify use-cases where batch processing would be helpful
- Create, run, and test batch jobs
- Structure batch jobs into workflows of steps
- Create fault-tolerant batch jobs
Before you begin
Course Prerequisites

- Working knowledge of Spring Boot
Course Outline
Spring Batch Overview
Learn a bit about batch processing, and how Spring Batch is a world-class tool for building batch processing applications.
Lab: Bootstrap the project
Create a brand new Spring Batch application using Spring Initializr.
Understanding jobs and how to run them
Learn the fundamentals of what makes up a Spring Batch application.
Lab: Implement Your First Job
Create a real Spring Batch job, run it, and learn how to inspect the results.
Understanding Job Instances
Learn about Job Instances, Job Parameters, and how they play a key role in all Spring Batch applications.
Lab: Using Job parameters to create Job Instances
Put your new-found Job Instances and Job Parameters knowledge to work in this Lab!
Lab: Testing Your Job
You'll update our application to make our tests thorough and re-runnable.
Understanding Steps
Take a step in the right direction by learning how Steps are a fundamental building-block of Spring Batch applications.
Using Steps
You know what Steps are, but how do you use them? You're about to learn how!
Lab: First Step
Knowledge is great, but how about action? Let's implement Steps in our application.
Reading and Writing Data
All that data we're processing needs to go somewhere! Learn about reading and writing data.
Lab: Reading and Writing Data
Would you like to read CSVs and write to databases? Get ready to learn!
Processing Data
Learn the main API for data processing and how to use it within a chunk-oriented step.
Lab: Processing Data
Update our Spring Batch application with chunk-based data processing.
Batch Scoped Components
Scope out @StepScope and learn how to supply Spring Batch parameters at runtime.
Lab: Batch Scoped Components
Use @StepScope and SpEL to make our batch job even smarter at runtime.
State management and restartability
Learn the various techniques Spring Batch uses to handle failures and rerun jobs.
Lab: Restarting failed jobs
Not everything is as fine as baguettes and brie. We'll fix a bad data-file and rerun our Spring Batch job.
Handling non-transient errors with skips
We can't just stop the world anytime we want to. Learn how and when to tell Spring Batch to skip bad data for later consideration.
Lab: Skipping invalid records
Implementing skipping invalid records is as easy as skipping through a field of daisies!
Handling transient errors with retries
Surprise! Technology can be flaky. Learn how to retry Steps when transient errors occur.
Lab: Retrying processing errors
Implement the retry feature in this lab!
