我正在尝试开发用于发送电子邮件的 Spring Boot 应用程序。一切都很好，但是在模板 thymeleaf 中，当我尝试添加图像时，它显示错误。
这是我的 template.html 的一个片段
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title th:remove="all">Order Confirmation</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>
<body>
<div>
<h2 th:text="${title}">title</h2>
<p th:utext="${description}">
description
</p>
<br />
<br />
<br />
<p>Bien cordialement</p>
<div>
<img th:src="@{/img/signature.png}" />
</div>
</div>
</body>
</html>
这是错误：

此致
对我来说这有效；只需删除“/”
<img th:src="@{img/signature.png}"/>
