推荐答案
您需要确保请求URL(在浏览器地址栏中输入)与FacesServlet的url-pattern相匹配. IE.不要通过 http://example.com/context/page.xhtml 打开页面，但是通过 http://example.com/context/page.jsf 打开它.否则，将不会调用FacesServlet，并且不会以任何方式解析带有JSF组件的XHTML页面.您将在浏览器中仅看到诸如<fieldset>之类的纯HTML"标签，并且在浏览器中执行 View Source 时，返回的HTML源中的JSF源代码将保持不变.
You need to make sure that the request URL (as you enter in browser address bar) matches the url-pattern of the FacesServlet. I.e. do not open the page by http://example.com/context/page.xhtml, but open it by http://example.com/context/page.jsf. Otherwise the FacesServlet will not be invoked and your XHTML page with JSF components will not be parsed in any way. You'll only see "plain HTML" tags like <fieldset> and so on in the browser and you will see the JSF source code unchanged in the returned HTML source when you do a View Source in browser.
