<ul>
<li><code>*</code>:表示匹配该域的任意值,假如在 <code>分钟</code> 域使用 <code>*</code>,即表示每分钟都会触发事件。</li>
<li><code>?</code>:只能用在 <code></code><code>星期</code> 两个域。它也匹配域的任意值,但实际不会。因为 <code></code><code>星期</code> 会相互影响。例如想在 <code>每月的20日</code> 触发调度,不管 20 日到底是星期几,则只能使用如下写法:<code>13 13 15 20 * ?</code>, 其中最后一位只能用 <code>?</code>,而不能使用 <code>*</code>,如果使用 <code>*</code> 表示不管星期几都会触发,实际上并不是这样。</li>
<li><code>-</code>:表示范围,例如在 <code>分钟</code> 域使用 <code>5-20</code>,表示从 <code>5分</code><code>20分钟</code> 每分钟触发一次。</li>
<li><code>/</code>:表示起始时间开始触发,然后每隔固定时间触发一次,例如在 <code>分钟</code> 域使用 <code>5/20</code>,则意味着 <code>5分钟</code> 触发一次,而 <code>2545</code> 等分别触发一次。</li>
<li><code>,</code>:表示列出枚举值。例如:在 <code>分钟</code> 域使用 <code>5,20</code>,则意味着在 <code>第5</code><code>第20分钟</code> 分别触发一次。</li>
<li><code>L</code>:表示最后,只能出现在 <code>星期</code><code>月份</code> 域,如果在 <code>星期</code> 域使用 <code>5L</code>,意味着在 <code>最后的一个星期四</code> 触发。</li>
<li><code>W</code>:表示有效工作日(周一到周五),只能出现在 <code></code> 域,系统将在离指定日期的最近的有效工作日触发事件。例如:在 <code></code> 使用 <code>5W</code>,如果 <code>5日是星期六则将在最近的工作日星期五即 4日 触发</code>。如果 <code>5日是星期天则在6日(周一)触发</code>;如果 <code>5日在星期一到星期五中的一天则就在 5日 触发</code>。另外一点,<code>W</code> 的最近寻找不会跨过月份。</li>
<li><code>LW</code>:这两个字符可以连用,表示在某个月最后一个工作日,即最后一个非周六周末的日期。</li>
<li><code>#</code>:用于确定每个月第几个星期几,只能出现在 <code>星期</code> 域。例如在 <code>2#3</code>,表示某月的第二个星期三。</li>
