代码语言：javascript复制/**
* Annotation that marks a method to be scheduled. Exactly one of the
* {@link #cron}, {@link #fixedDelay}, or {@link #fixedRate} attributes must be
* specified.
*
* <p>The annotated method must expect no arguments. It will typically have
* a {@code void} return type; if not, the returned value will be ignored
* when called through the scheduler.
*
* <p>Processing of {@code @Scheduled} annotations is performed by
* registering a {@link ScheduledAnnotationBeanPostProcessor}. This can be
* done manually or, more conveniently, through the {@code <task:annotation-driven/>}
* element or @{@link EnableScheduling} annotation.
*
* <p>This annotation may be used as a <em>meta-annotation</em> to create custom
* <em>composed annotations</em> with attribute overrides.

public class CronSequenceGenerator {通过源码和源码中的例子，我们可以看到自从Spring3.0的版本后，cron表达式只能支持6个字段
