Spring Boot CSS在尝试所有内容后显示为空白/未加载
提问于 2016-12-09 17:25:43
我是Spring Boot的新手，目前我正在阅读这本书。Spring Boot正在运行。
我创建并编译了我的第一个web简单web应用程序，很好，预计css文件在控制台中显示为空白。我已经查阅了下面的帖子：
我使用的是百里叶，我的css文件被放在静态文件夹中，就像文章和书中所说的那样，但是什么也没有显示出来。我目前的外部链接，似乎也是正确的方式。
<link rel="stylesheet" th:href="@{/main.css}" />尽管css似乎显示在console的资源中，但css文件仍为空。下面是我的文件和代码。
文件结构：
模板：
body {
background-color: #cccccc;
font-family: arial,helvetica,sans-serif;
}
.bookHeadline {
font-size: 12pt;
font-weight: bold;
}
.bookDescription {
font-size: 10pt;
}
label {
font-weight: bold;
} <html xmlns:th="http://www.springframework.org/schema/data/jaxb">
<head>
<title>Reading List</title>
<link rel="stylesheet" th:href="@{/main.css}" />
</head>
<body>
<h2>Your Reading List</h2>
<div th:unless="${#lists.isEmpty(books)}">
<dl th:each="book : ${books}">
<dt class="bookHeadline">
<span th:text="${book.title}">Title</span> by
<span th:text="${book.author}">Author</span>
(ISBN: <span th:text="${book.isbn}">ISBN</span>)
</dt>
<dd class="bookDescription">
<span th:if="${book.description}"
th:text="${book.description}">Description</span>
<span th:if="${book.description eq null}">
No description available</span>
</dd>
</dl>
</div>
<div th:if="${#lists.isEmpty(books)}">
<p>You have no books in your book list</p>
</div>
<hr/>
<h3>Add a book</h3>
<form method="POST">
<label for="title">Title:</label>
<input type="text" name="title" size="50"></input><br/>
