Triggerを利用してnext execution timeを指定

@Configuration

@Autowired
Environment env;
@Bean
public MyBean myBean() {
return new MyBean();
}
@Bean(destroyMethod = "shutdown")
public Executor taskExecutor() {

}
@Override
public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
taskRegistrar.setScheduler(taskExecutor());
taskRegistrar.addTriggerTask(
new Runnable() {
@Override public void run() {
myBean().getSchedule();
}
},
new Trigger() {
@Override public Date nextExecutionTime(TriggerContext triggerContext) {
Calendar nextExecutionTime = new GregorianCalendar();
Date lastActualExecutionTime = triggerContext.lastActualExecutionTime();
nextExecutionTime.setTime(lastActualExecutionTime != null ? lastActualExecutionTime : new Date());
nextExecutionTime.add(Calendar.MILLISECOND, env.getProperty("myRate", Integer.class)); //you can get the value from wherever you want
return nextExecutionTime.getTime();
}
}
);
}
