Answer 1

应关闭所有标签。在您的情况下，inputPassword和inputEmail未关闭。

Answer 2

您的输入标记应该像这样关闭，

<input type="email" id="inputEmail" class="form-control" placeholder="Email address" th:required="required" />

代替

<input type="email" id="inputEmail" class="form-control" placeholder="Email address" th:required="required">

元素类型＆＃34;输入＆＃34;必须由匹配的结束标记终止＆＃34;＆＃34;＆{34;
