java - primefaces 可以与facelets 一起使用吗？

Question

我正在使用在 tomcat 服务器上运行的 JSF 2.0 构建一个 Java Web 应用程序。我正在使用 facelets1.1.10 。我最近看到了 primefaces 的功能，并且给我留下了深刻的印象。所以我想将 primefaces 添加到我的网络项目中。

我从网站下载了 primefaces3.2.jar 并将其添加到我的项目 lib 文件夹(我保存所有 jar 的地方)。并将其添加到我的构建路径中。但是当测试它以查看 primefaces 是否有效时，我收到以下错误:

这是什么意思？我必须做什么才能保留facelets并添加primefaces？

Answer 1

是的，它正在与 Facelets 一起使用...(Facelets 2.0)

看看 BalusC 的详细回答 Migrating from JSF 1.2 to JSF 2.0

原始 BalusC 答案的一些片段...

Facelets 1.x 到 Facelets 2.0

如果您使用 Facelets 1.x 作为 View 技术，并希望使用 JSF 2.0 提供的 Facelets 2.0，那么您需要执行以下附加步骤:

• 从 /WEB-INF/lib 中删除 Facelets 1.x JAR .
• 删除 Facelets 1.x FaceletViewHandler来自faces-config.xml .
• 任何自定义 FaceletViewHandler需要更新实现以扩展 [ ViewHandlerWrapper ][2] 相反。
• 不必要，但只是为了清理，删除任何与 Facelets 1.x 相关的 <context-param>值来自web.xml Facelets 2.0 中已经默认，例如 javax.faces.DEFAULT_SUFFIX值为*.xhtml .

• 更新现有 Facelet 标记库 XML 的根声明以符合 Facelets 2.0。
