Batch processing remains essential in many IT architectures: data import/export, document generation, recurring calculations or intensive business processing. Spring Batch provides a powerful, proven framework for structuring, scheduling, restarting and ensuring the reliability of such processes in modern environments. In this course, you'll learn how to organize workflows in the form of jobs, break down steps into tasklets or chunk-oriented processes, pass on parameters and manage recovery strategies (retry, skip, listeners). You'll also see how to make your jobs interact with the Spring Boot environment: transaction management, launching via command line or tests, automatic configuration... Each concept is immediately put into practice in a “red thread” project in which you will build all the building blocks, step by step. At the end of the day, you'll have a solid technical foundation for integrating high-performance, testable batch processes tailored to your business processes.
Objectives
Master the design and implementation of batch processing in Java with Spring Batch, structuring the process in the form of jobs made up of workflows, steps and reusable components.
Is it for you ?
Developers and architects.
Prerequisite
This course requires a sound knowledge of the basics of Java programming (principles of object-oriented programming, generic types, annotations, lambda expressions), Spring and Spring boot and experience of working with Eclipse or IntelliJ.

Introduction
- Overview of concepts and use cases.
- The job tracking database used by Spring Batch.
- The role of beans automatically created by Spring Boot (JobLauncher, JobRepository...).
Practical application: creation of a Spring Boot project to develop a Spring Batch job, creation of the job tracking database.

Job definition
- A Job as a set of flows and steps.
- Sequential workflows.
- Conditional workflows.
- Parallel workflows.
- Possible Job statuses.
- JobScope and StepScope scopes.
- Best practices for organizing code.
Putting it into practice: creating a simple Job.
Starting a job
- Transmission of parameters (JobParameters).
- Launching from the command line.
- Launch from a Spring schedule.
- Launch from a test with spring-batch-test
Putting it into practice: executing the Job defined above from the main method and from a test.
Step definition
- Transactional demarcation.
- Access to JobParameters.
- Step-oriented chunks and their components: ItemReader,ItemProcessor, ItemWriter.
- Tasklet steps.
- Error tolerance (skip, retry).
- Listeners.
Practical application: add chunk oriented steps and tasklet steps to the Job created previously, apply a retry strategy and declare listeners.
