Spring Batch Architecture

Spring Batch is designed with extensibility and a diverse group of end users in mind. The figure below shows a sketch of the layered architecture that supports the extensibility and ease of use for end-user developers.

Figure : Spring Batch Layered Architecture

This layered architecture highlights three major high level components:

• Application

• Core

• Infrastructure.

The application contains all batch jobs and custom code written by developers using Spring Batch.

The Batch Core contains the core runtime classes necessary to launch and control a batch job. It includes things such as aJobLauncher, Job, and Step implementations. Both Application and Core are built on top of a common infrastructure.

This infrastructure contains common readers and writers, and services such as the RetryTemplate, which are used both by application developers(ItemReader and ItemWriter) and the core framework itself.
