我不知道是什么问题，我没有语法错误，但我应该有一个导航栏在我的屏幕顶部，但它没有显示出来。语法中有什么需要修改的吗？我是否也在默认模板文件中遗漏了什么？我的网页显示良好，但我只是缺少我的图像和导航栏。
common.html文件

更换

<img th:src="@{/static/images/gcu-logo.jpg}" /><br

如果是导航栏
第一css链接不可访问而不是

https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css.bootstrap.min.css
 https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css.bootstrap-theme.min.css

字符串
应该是

https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css
https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap-theme.min.css

第二：当设置样式class时，您缺少th，即对于单个类，应为th:class="class-name"，对于多个类，应为th:classappend="|class1 class2 class3|"
第三：要使导航按钮在菜单折叠时显示菜单，data-target值应该是.navbar-collapse而不是navbarCollapse
下面的完整示例加载可折叠的导航栏
