How to access the jobParameters inside itemReader

[geira]

I have a factory-method: getTickerJobQuery providing a dynamic sql input to the JdbcCursorItemReader.

How could I get hold of the jobParameters, - and provide them as input to either the JdbcCursorItemReader, - or to the getTickerJobQuery?

Or suggest another approach..

Just make it a StepExecutionListener:

http://static.springframework.org/sp...n.html#d0e3811

You can then call stepExecution.getJobParameters()

[geira]

I have a problem with the StepExecutionListener is called after the ItemReader is initialized. How could I make use of jobParameters retrieved via the StepExecutionListener in the ItemReader?

Can the values from the JobParameters not be set via the PreparredStatementSetter?
