当我在Spring-boot中配置thymeleaf和Bootstrap时，我无法导入Bootstrap静态资源。我知道有很多类似的问题，但我无法为我解决。
如果我使用网络资源
<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">
，它适用于我，但我需要使用静态资源，当我进行以下配置，它给我404错误
像这样的网页， book.html：
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.w3.org/1999/xhtml" >
<head>
<meta charset="UTF-8"/>
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>book</title>
<link th:href="@{/css/bootstrap.css}" rel="stylesheet"/>
</head>
<body>
<div class="container" style="max-width: 700px;">
<h2 class="page-header" style="margin-top: 70px;">note</h2>
<div class="well" th:object="${book2}">
<p>
<strong>at:</strong><span th:text="*{at}">default</span>
</p>
<p>
<strong>name:</strong><span th:text="*{name}">default</span></p>
<p>
<strong>number:</strong><span th:text="*{number}">default</span></p>
<p>
<strong>retest:</strong><span th:text="*{retest}">default</span></p>

spring-boot yml设置，我使用过“context-path：/ path”，
我不知道它是否会影响资源路径。 应用uat.yml：
