Looks like you are missing the 'active' class in the second label. Is this what you were looking for?
看起来您在第二个标签中缺少“活动”类。这就是你要找的吗?
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-default">
<input type="checkbox">Hello 1
</label>
<label class="btn btn-default active">
<input type="checkbox" checked="checked">Hello 2
</label>
<label class="btn btn-default">
<input type="checkbox">Hello 3
</label>
</div>

See Bootstrap's bleeding-edge docs:
请参阅Bootstrap 的前沿文档:
Pre-checked options need
.activeFor pre-checked options, you must add the
.activeclass to the<input>'s<label>yourself.
需要预先检查的选项
.active对于预先检查的选项,您必须将
.active类添加到<input>'s 中<label>。
