Thymeleaf 绝对路径

在网上搜索到的大部分解决方案都是^[1]：

<a th:href="${#httpServletRequest.getScheme() + '://' + #httpServletRequest.getServerName() + ':' + #request.getServerPort()  + #request.getContextPath() + @{/login}} ">点我啊！</a>

其中：

getScheme()获取协议
getServerName()获取服务器名
getServerPort()服务器端口
getContextPath() APP根路径

然而将代码复制修改后的效果是：

前台报错

Thymeleaf 绝对路径

后台报错

Thymeleaf 绝对路径

org.springframework.expression.spel.SpelParseException: Expression [#httpServletRequest.getScheme() + '://' + #httpServletRequest.getServerName() + ':' + #request.getServerPort()  + #request.getContextPath() + @{/login}] @142: EL1059E: @ or & can only be followed by an identifier or a quoted name

根据报错信息，对方案略微修改：

将@{/admin} 修改为 '/admin'

<a th:href="${#httpServletRequest.getScheme() + '://' + #httpServletRequest.getServerName() + ':' + #request.getServerPort()  + #request.getContextPath() + '/admin'}">跳转主页</a>
