问题描述

我有以下gsp代码:

<p class="common-text ">${direction?.description?.toHtml()?.decodeHTML()}</p>

direction?.description是用户在某些输入字段中输入的文本.该文本可能包含网站网址，例如Visit my new site www.example.com

direction?.description is a text which the user entered in some input field. This text could includes website URLs like Visit my new site www.example.com

如何验证某些文本中是否包含URL，并显示为超链接?

上面的文本应转换为以下内容:

The text above should be transformed to something like:
