带有变量的百里香绝对 URL [英] thymeleaf absolute URL with variable

问题描述

我正在尝试使用 Thymeleaf 将域 url 注入到链接中.我的 url 是从控制器传递过来的，因为我记录了日志并看到了它.

I am trying to inject a domain url into a link using Thymeleaf. My url is being passed from the controller because i put logging and saw it.

我的链接在我的 Thymeleaf html 模板中是这样的:

my link is as such in my Thymeleaf html template:

<link type="text/css" th:href="@{${DomainUrl}/web/assets/css/foundation5/foundation.min.css}" rel="stylesheet" />

但是，当我在本地运行它时，它不会替换域，例如，抛出一个错误(因为当然找不到 URL)渲染如下:http://localhost:8081/pss/ui/$%7BDomainUrl%7D/web/assets/css/components.css

however, when I run it locally it doesn't replace the domain, for example, throws an error (because the URL is not found of course) render as such: http://localhost:8081/pss/ui/$%7BDomainUrl%7D/web/assets/css/components.css

推荐答案

好吧，为了让它起作用，你必须使用预处理运算符 __expression__ 来获取属性链接，这样你最终会得到一些想法这个

Ok so in order for this to work you must use preprocess operator __expression__ to get propert link so you will end up with somethink like this

<link type="text/css" th:href="@{__${DomainUrl}__/web/assets/css/foundation5/foundation.min.css}" rel="stylesheet" />

这将预处理和解析 ${DomainUrl} 表达式，并将结果字符串传递给 @ 表达式处理器.经过测试和工作的魅力:

this will preprocess and resolve ${DomainUrl} expression, and will pass resulting string to to @ expression processor. Tested and work like charm:

<a th:href="@{__${currentUrl}__/blah/blah/blahhhh}">hey there</a>

生成

<a href="http://localhost:8080/admin/place/list/blah/blah/blahhhh">hey there</a> 

其中 http://localhost:8080/admin/place/list/ 是 currentUrl
