You can set the property "autoStart" of CronSchedulerBean to false, this would mean that Cron job will be not executed after application starts. Once you are ready with proper parameters, you can enable cron job.

See this api: http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/scheduling/quartz/SchedulerFactoryBean.html#setAutoStartup(boolean)
