<p>顾名思义，定时任务就是在特定的时间或符合某种时间规律执行的任务。通常定时任务有四种时间调度方式：</p>
<ul>
<li><code>缓隔时间</code> 方式：延迟多少时间后调配任务，这种方式任务只会被调用一次。</li>
<li><code>间隔时间</code> 方式：每隔一段固定时间调配任务，无间断调用任务。</li>
<li><code>Cron 表达式</code> 方法：通过 <code>Cron</code> 表达式计算下一次执行时间进行调配任务，可以配置特定时间范围内执行，也可以无间断执行。</li>
<li><code>自定义下次执行时间</code>：可以通过各种逻辑运算返回下一次执行时间</li>
</ul>

<p><code>Furion</code> 框架提供了两种方式实现定时任务：</p>
<ul>
<li><code>SpareTime</code> 静态类：<code>SpareTime</code> 静态类提供 <code>SpareTime.Do([options])</code> 方式调用。</li>
<li><code>ISpareTimeWorker</code> 依赖方式：通过自定义类实现 <code>ISpareTimeWorker</code> 接口并编写一定规则的方法即可。<strong>需要在 <code>Startup.cs</code> 中注册 <code>services.AddTaskScheduler()</code></strong></li>
</ul>

<p>Cron 表达式是一个字符串，字符串以 <code>5</code> 或 <code>6</code> 个空格隔开，分为 6 或 7 个域，每一个域代表一个含义，Cron 有如下两种语法格式：</p>
<p>（1） Seconds Minutes Hours DayofMonth Month DayofWeek Year</p>
<p>（2）Seconds Minutes Hours DayofMonth Month DayofWeek</p>
<p>Cron 从左到右（用空格隔开）：<code>秒</code> <code>分</code> <code>小时</code> <code>月份中的日期</code> <code>月份</code> <code>星期中的日期</code> <code>年份</code></p>
<table><thead><tr><th>字段</th><th>允许值</th><th>允许的特殊字符</th></tr></thead><tbody><tr><td>秒（Seconds）</td><td><code>0~59</code> 的整数</td><td><code>, - \* /</code> 四个字符</td></tr><tr><td>分（Minutes）</td><td><code>0~59</code> 的整数</td><td><code>, - \* /</code> 四个字符</td></tr><tr><td>小时（Hours）</td><td><code>0~23</code> 的整数</td><td><code>, - \* /</code> 四个字符</td></tr><tr><td>日期（DayofMonth）</td><td><code>1~31</code> 的整数（但是你需要考虑平闰月的天数）</td><td><code>,- \* ? / L W C</code> 八个字符</td></tr><tr><td>月份（Month）</td><td><code>1~12</code> 的整数或者 <code>JAN-DEC</code></td><td><code>, - \* /</code> 四个字符</td></tr><tr><td>星期（DayofWeek）</td><td><code>1~7</code> 的整数或者 <code>SUN-SAT （1=SUN）</code></td><td><code>, - \* ? / L C #</code> 八个字符</td></tr><tr><td>年(可选，留空)（Year）</td><td><code>1970~2099</code></td><td><code>, - \* /</code> 四个字符</td></tr></tbody></table>
<p>每一个域都使用数字，但还可以出现如下特殊字符，它们的含义是：</p>
<p>（1）<code>_</code>：表示匹配该域的任意值。假如在 <code>Minutes</code> 域使用 <code>\_</code>, 即表示每分钟都会触发事件。</p>
<p>（2）<code>?</code>：只能用在 <code>DayofMonth</code> 和 <code>DayofWeek</code> 两个域。它也匹配域的任意值，但实际不会。因为 <code>DayofMonth</code> 和 <code>DayofWeek</code> 会相互影响。例如想在每月的 <code>20</code> 日触发调度，不管 <code>20</code> 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_，如果使用*表示不管星期几都会触发，实际上并不是这样。</p>
<p>（3）<code>-</code>：表示范围。例如在 <code>Minutes</code> 域使用 <code>5-20</code>，表示从 <code>5</code> 分到 <code>20</code> 分钟每分钟触发一次</p>
<p>（4）<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>Minutes</code> 域使用 <code>5/20</code>，则意味着 <code>5</code> 分钟触发一次，而 <code>25，45</code> 等分别触发一次.</p>
<p>（5）<code>,</code>：表示列出枚举值。例如：在 <code>Minutes</code> 域使用 <code>5,20</code>，则意味着在 <code>5</code> 和 <code>20</code> 分每分钟触发一次。</p>
<p>（6）<code>L</code>：表示最后，只能出现在 <code>DayofWeek</code> 和 <code>DayofMonth</code> 域。如果在 <code>DayofWeek</code> 域使用 <code>5L</code>,意味着在最后的一个星期四触发。</p>
<p>（7）<code>W</code>：表示有效工作日(周一到周五) 只能出现在 <code>DayofMonth</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>DayofMonth</code> 使用 <code>5W</code>，如果 <code>5</code> 日是星期六，则将在最近的工作日：星期五，即 <code>4</code> 日触发。如果 <code>5</code> 日是星期天，则在 <code>6</code> 日(周一)触发；如果 <code>5</code> 日在星期一到星期五中的一天，则就在 <code>5</code> 日触发。另外一点，<code>W</code> 的最近寻找不会跨过月份 。</p>
<p>（8）<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，即最后一个星期五。</p>
<p>（9）<code>#</code>：用于确定每个月第几个星期几，只能出现在 <code>DayofMonth</code> 域。例如在 <code>4#2</code>，表示某月的第二个星期三。</p>

<p>除了上面的 <code>SpareTime</code> 静态类方式，<code>Furion</code> 框架还提供了 <code>ISpareTimeWorker</code> 方式，使用该方式非常简单，只需要自定义一个<strong>公开且非抽象非静态</strong>类并实现 <code>ISpareTimeWorker</code> 即可。</p>
<p>在该类中定义的任务方法需满足以下规则：</p>
<ul>
<li>必须是<strong>公开且实例方法</strong></li>
<li>该方法必须返回 <code>void</code> 且提供 <code>SpareTimer</code> 和 <code>long</code> 两个参数</li>
<li>必须贴有 <code>[SpareTime]</code> 特性</li>
