Working with Spring Batch

Course Objectives

Working in a hands-on learning environment, students will explore the Spring framework, with emphasis placed on Spring Batch. Throughout the course students will:

• Understand how to leverage the power of Spring Boot to develop Spring Batch applications
• Use Spring Batch to define batch jobs
• Define the batch workflow
• Understand how Spring Batch manages the state of each job
• Restart Jobs in case of failures during execution
• Schedule Batch Jobs
• Use Spring Cloud Data flow to monitor the batch jobs
• Test the implementation of the Batch process
• Test the implementation of individual steps of a Batch Job
