+                        解释： 由于原生的 HTML 解析行为的限制，单个闭合标签可能会导致一些例外情况，所以请使用双封闭标签，
+                        
+                        详细解释：然而在 DOM 内模板中，我们必须显式地写出关闭标签：
+                        <my-component></my-component>
+                        这是由于 HTML 只允许一小部分特殊的元素省略其关闭标签，最常见的就是 <input> 和 <img>。对于其他的元素来说，如果你省略了关闭标签，原生的 HTML 解析器会认为开启的标签永远没有结束
