我正在尝试按照以下教程创建一个将 primefaces 与 spring boot 集成的应用程序:
https://codenotfound.com/jsf-primefaces-example.html
我按照教程的建议添加了连接面:
这是我的pom.xml

我创建了 webapp/WEB-INF 文件夹结构:
正如您在图像上看到的,webapp 文件夹看起来不像是被 intellij 识别的。
另一个问题是 xmlns:p="http://primefaces.org/ui" 正如您在图像上看到的那样,url taglib 未被识别。
所以当我在浏览器上运行时:http://localhost:8080/eleicao.xhtml 浏览器返回错误:
出现意外错误(类型=未找到,状态=404)。 在ExternalContext 中未找到/eleicao.xhtml 作为资源
那么我该如何解决这个问题呢?这样我就可以运行 primefaces 页面。
您缺少了一堆依赖项,这里是我的 PrimeFaces、MyFaces for JSF、OmniFaces 和 Undertow 作为 servlet 引擎的 pom
<!-- JoinFaces -->

一段时间后,我尝试做与你相同的事情,并在 IntelliJ Idea 上遇到相同的错误。
在我的例子中,我发现一些外部jar(通过maven包含)丢失了,但即使它们在那里,它们也无法正常工作。
在 IntelliJ 中,我什至尝试删除 .m2 chache 并从零开始下载所有内容,通过文件 > 无效缓存忽略所有 chache,但不幸的是效果不佳。
我尝试手动包含丢失的 .jar,但没有任何效果
在阅读了大量内容并尝试了一堆解决方案后,我尝试在 Eclipse 中打开该项目,因为没有任何意义。
令我惊讶的是……一切都很好。我相信在考虑这个解决方案时,这应该是 IntelliJ 上的一个错误。
这是我的pom.xml
