spring boot + thymeleaf 3+bootStrap， Configuration bootstrap return 404 error

I can't import Bootstrap static resources when I configure thymeleaf and Bootstrap in Spring-boot. I know there are many similar problems, but I can't solve them for me.

if i use web resources like

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">

，it work for me ,but i need to use static resources， When I made the following configuration，and it give me 404 error

the web page like this,
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>
</div>
</div>

spring-boot yml setting,I had used "context-path: /path",

I don't know if it will affect the resource path.
application-uat.yml:

server:
  port: 8081
  servlet:
    context-path: /path    
logging:
  level:

  at: at參數${random.uuid}
  retest: ${book.name},try it

Try changing

<link th:href="@{/css/bootstrap.css}" rel="stylesheet"/>

to

<link href="/css/bootstrap.css" rel="stylesheet" th:href="@{/css/bootstrap.css}">
