I checkout this project from spring: https://github.com/spring-guides/gs-batch-processing

I replace the ',' with 'tab' in 'sample-data.csv:
...ANSWER
Answered 2018-Aug-08 at 07:55You cant't set the tab delimiter that way. Since tab ('\t') doesnt contain any actual text it is ignored by the DelimitedLineTokenizer in static DelimitedBuilder class in FlatFileItemReaderBuilder.java . Any non-whitespace delimiter can be set using above code that you have given in the question.
FlatFileItemReaderBuilder sourceCode
This is how the LineTokenizer instance is built in FlatFileItemReaderBuilder.java.

QUESTION
I am using a batch process and i want it to run at a specific cron scheduled time. However, the job is getting triggered at the start up and again triggering at the scheduled time. I am trying to avoid the former however failing to do so. This is a sample repository which reproduces the same issue: https://github.com/ppanigrahi02/BatchJobWithScheduler. i am using the spring guide example https://github.com/spring-guides/gs-batch-processing and added a scheduler on top of it. I will really appreciate any leads.
...ANSWER
Answered 2018-Feb-08 at 11:42The @Scheduled annotation used here will start the job immediately at startup and every 600000 milliseconds. If you want to specify an initial delay to wait before the first execution, you can use the initialDelay attribute of the annotation, something like:
@Scheduled(initialDelay = 600000, fixedRate = 600000)
Another option is to use the cron attribute and provide a cron expression. For more details about this annotation, you can check the reference documentation here: https://docs.spring.io/spring/docs/5.0.3.RELEASE/spring-framework-reference/integration.html#scheduling-annotation-support-scheduled
