Reload a spring batch Job

Question

We need to change an already running job. We should be able to push the job change without restarting the server.

Is it possible to reload a Spring batch job after the jobs / application context has been loaded.

Answer 1

The DefaultJobLoader allows you to reload the application context for your jobs.

Answer 2

Dynamic job deployment and editing of deployed job configurations (without requiring a server restart) is a feature we implemented in Trooper Batch profile (built on Spring Batch and Spring Batch admin). Screen shots are here : https://github.com/regunathb/Trooper/wiki/Writing-Batch-jobs-in-Trooper
