That's possible with a custom UIComponent . 使用自定义UIComponent可以实现这一点。 My colleague Arjan Tijms has written a blog article about this 2 years ago: Facelets and legacy JSP . 我的同事Arjan Tijms在2年前撰写了一篇博客文章： Facelets和遗留JSP 。

It's some code, but the principle is easy, the component does a RequestDispatcher#include() with a custom HttpServletResponseWrapper which captures the written output and then writes it to the body of the JSF component. 这是一些代码，但原理很简单，组件使用自定义HttpServletResponseWrapper执行RequestDispatcher#include() ，它捕获写入的输出，然后将其写入JSF组件的主体。

Since recently, this component is also available as <o:resourceInclude> of the OmniFaces library, maintained by Arjan and me. 从最近开始，这个组件也可以作为OmniFaces库的<o:resourceInclude> ，由Arjan和我维护。

Last but not least, I'd like to repeat his last words. 最后但并非最不重要的是，我想重复他的最后一句话。

I wouldn't recommend using this as a lasting solution, but it might ease a migration from legacy JSP with smelly scriptlets and all on them to a more sane and modern Facelets application. 我不建议使用它作为一个持久的解决方案，但它可以简化从带有臭臭小脚本的遗留JSP的迁移，以及所有这些对更健全和更现代的Facelets应用程序的迁移。
