2.4. Summary

This chapter is rich in Spring Batch concepts and terminology! Using a now well-defined vocabulary, you can paint a clear picture of your batch applications. You learned how the Spring Batch framework models these concepts, an important requirement to understanding how to implement batch solutions. You saw the static and dynamic aspects of jobs: static by modeling and configuring jobs with steps, dynamic through the job runtime handling of job instances and executions. Restarting failed jobs is an important requirement for some batch applications, and you saw how Spring Batch implements this feature by storing job execution metadata; you also saw the possibilities and limitations of this mechanism.

With this picture of the Spring Batch model in mind, let’s move on to the next chapter and see how to configure our batch applications with the Spring lightweight container and Spring Batch XML.
