Thymeleaf 解析文本并执行文本内表达式 [英] Thymeleaf parse text and execute in-text expressions

问题描述

我有包含链接的文本字符串，例如 .我观察到，一旦 thymeleaf 的命名空间 th: 限定了位于文本/字符串中的 href 或 src 属性，则绝对路径无法正确解析.

I have text string, that contains links, for example, like <a th:href="'someLink'">Download</a> .

I need to process that text and replace th:href="'someLink'" with correct links to show text with <a href="someLink">Download</a>.

The text with links is stored in variable textThatContainsLinks.

My code to show text is <div th:utext="${textThatContainsLinks}">. I also tried to use preprocessing like <div th:utext="${__textThatContainsLinks__}">.

Currently this code shows links not as I expected, but non-preprocessed, ie, output is <a th:href="'someLink'">Download</a> now.

How to pre-process expressions in text, before showing it?

Thank you very much!

解决方案

Take the context path and directly attach it to the relative path of a pure html5 attribute e.g <a href="/contextPath/relative/path">LINK</a>, <img src="/contextPath/relative/path/image.jpg" width="50" height="50" alt="logo"/>. Notice how simple the accessibility to the resource is: /contextPath/relativePath, so the most important path there is the relative path. This is similar to Thymeleaf was unable to render <img> tag when sent from database table. I observed that once thymeleaf's namespace th: qualifies a href or src attribute that resides inside a text/String the absolute path is not properly resolved.
