Spring Batch FlatFileItemWriter - How to use stepExecution.jobId to generate file name

Question

I have this FileWriter where I\'m trying to append the current Job Id to the filename that is generated.

Answer 1

The supported names for late-bindig are:

• #{jobParameters}
• #{jobExecutionContext}
• #{stepExecutionContext}

If jobId is not directly accessible, look this question.

Also, resource can be injected directly as

  file://${csv.file}_#{jobExecutionContext['jobId']}

because the right resource type is created using a converter.
