In the course Spring Batch participants learn to use the open source Framework Spring Batch for batch applications that require the processing of large amounts of data without human intervention. Spring Batch has reusable functions that are essential when processing large numbers of records and supports logging, transaction management, job processing statistics as well as restarting or skipping jobs.
The course starts with an overview of the architecture of the Spring Batch Framework and the essentials of Spring and Spring Boot. The parts of Spring Batch are explained here, such as Jobs, Steps, ItemReaders, ItemProcessors and ItemWriters.
Next the configuration of Jobs and the role of Job Parameters are discussed. Job Listeners, the Execution Context and persistence are also addressed.
Spring Batch typically uses a Chunk-oriented processing style where steps in a transaction are first read in, then processed and finally written. In the course this step processing is extensively treated including chunk size configuration and step listeners.
The role of Job Repositories with an in memory representation or by using databases and JobExplorers and JobLaunchers are also on the course schedule.
Finally after going into the details of ItemReaders, ItemProcessors and ItemWriters, attention is paid to tuning and making the batch processing scalable by using parallelization, multiple threads and asynchronous calls.
The course Spring Batch is intended for experienced Java Developers who want to use Spring Batch to process large amounts of data.
Experience with Java programming and object orientation is required to participate in this course. Prior knowledge of the Spring Framework is beneficial to good understanding.
The concepts are discussed on the basis of presentations and demos. The theory is interchanged with exercises. Course times are from 9:30 am to 16:30 pm.
After successful completion of the course the participants receive an official certificate Spring Batch.
