Passing Data to Future Steps in Spring Batch
An ExecutionContext is a set of key-value pairs containing information that is scoped to either StepExecution or JobExecution. Spring Batch persists the ExecutionContext, which helps in cases where you want to restart a batch run (e.g., when a fatal error has occurred, etc.). All that is needed is to put any object to be shared between steps into the context and the framework will take care of the rest. After restart, the values from the prior ExecutionContext are restored from the database and applied.
