作为测试，创建一个包含 和 PrimeFaces 组件的页面，在网络浏览器中打开该页面并通过右键单击检查生成的 HTML 源 - < em>查看源代码。您将看到添加了几个 JSF 和 PrimeFaces 特定的 JS/CSS 文件。现在将 替换为 并再次检查生成的 HTML 源代码，这次您将看不到任何内容。
The <h:head> is a JSF component which provides a hook to programmatically include JavaScript and CSS resources in the generated HTML <head>. PrimeFaces uses it to include the necessary JS/CSS code for the Ajax works and fancy look'n'feel.
As a test, create a page with a <h:head> and a PrimeFaces component, open the page in the webbrowser and check the generated HTML source by rightclick - View Source. You'll see that several JSF and PrimeFaces specific JS/CSS files are been added. Now replace <h:head> by <head> and check the generated HTML source once again, you'll see nothing this time.
The <head> tag is a HTML tag, which defines the head of the HTML page (this is where you define metadata, or include the resources such as JavaScript or CSS for example).
The <h:head> is a JSF tag (introduced with JSF 2.0) that handles the <head> part of your page. The interest of having such JSF tag is that this head becomes part of your JSF components tree, and thus, you can manipulate it in your Java code.
Regarding the <head> incompatibility with Primefaces, I don't see why it happens. Facelets introduced in JSF 1.x the ability to mix HTML code and JSF (XHTML) code, and you should not have any trouble to insert a HTML <head> tag in your page, even if you use Primefaces. Facelets is natively integrated with JSF 2.x.

与 Primefaces 不兼容，我不明白为什么会发生这种情况。 Facelets 在 JSF 1.x 中引入了混合 HTML 代码和 JSF (XHTML) 代码的能力，并且您在页面中插入 HTML标记应该不会有任何问题，即使您使用 Primefaces。 Facelets 本身就与 JSF 2.x 集成。<head>tag is a HTML tag, which defines the head of the HTML page (this is where you define metadata, or include the resources such as JavaScript or CSS for example).<h:head>is a JSF tag (introduced with JSF 2.0) that handles the<head>part of your page.
