Question

I am coding a spring application. I have a scheduled job like this.

@Async
@Scheduled(cron = "0 0 16 * * ?")
public void createReport()
{
    // argJasperPath = /WEB-INF/jasperFiles/myreport.jasper
    JasperPrint jasperPrint = JasperFillManager.fillReport(argJasperPath, argReportParams, argDataSource);
    JasperExportManager.exportReportToPdfFile(jasperPrint, argOutputPath);
}

This runs at 16:00 every day and create a report. I am using JasperReports for generating reports. I have myreport.jasper file under /WEB-INF/jasperFiles/myreport.jasper, when I run my job while generating report I get FileNotFound exception.

How can I reach my jasper files in my scheduled method?

Answer 1

@Autowired
ServletContext context;

@Async
@Scheduled(cron = "0 0 16 * * ?")
public void createReport()
{
    // argJasperPath = /WEB-INF/jasperFiles/myreport.jasper
    JasperPrint jasperPrint = JasperFillManager.fillReport(context.getRealPath(argJasperPath), argReportParams, argDataSource);
    JasperExportManager.exportReportToPdfFile(jasperPrint, argOutputPath);
}

If we autowire ServletContext we can reach directory like this: (context.getRealPath(argJasperPath)
