Answer 1

我的答案可能不能解决所有人的问题，首先在后台打印一下数据，确认不是后台的错误，前端页面的错误一般是由于私有属性造成的，解决办法就是调用get方法，如：
<tr th:each="user:${emps}">
<th scope="row" th:text="${user.getId()}"></th>
<td th:text="${user.getName()}"></td>
<td th:text="${user.getEmail()}"></td>
</tr>

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
Error
