thymeleaf 模板类 - 无法解析为表达式

问题描述 投票：0回答：1

我有这个工作正常的模板：

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org" lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="x-ua-compatible" content="ie=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link rel="shortcut icon" th:href="@{/images/logo.png}" type="image/x-icon"/>
    <title>Mystic River</title>
    <link rel="stylesheet" th:href="@{/css/style.css}" />
    <link rel="stylesheet" th:href="@{/css/responsive.css}" />
  </head>
  <body>
    <!-- Header -->
    <header class="header-wrapper header_fixed bg_transparent" id="header-wrapper">
....
</html>

但是使用时

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org" lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="x-ua-compatible" content="ie=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link rel="shortcut icon" th:href="@{/images/logo.png}" type="image/x-icon"/>
   <title>Mystic River</title>
    <link rel="stylesheet" th:href="@{/css/style.css}" />
    <link rel="stylesheet" th:href="@{/css/responsive.css}" />
  </head>
  <body>
    <!-- Header -->
    <header th:class="header-wrapper header_fixed bg_transparent" id="header-wrapper">

我有这个错误：

你有

class="header-wrapper header_fixed bg_transparent"

在第一个模板中并且

th:class="header-wrapper header_fixed bg_transparent"

在第二个（注意

th:class
而不是
class
）。 
"header-wrapper header_fixed bg_transparent"
不是有效的 Thymeleaf 表达式。
