Question

我有Springboot JSF应用程序在嵌入式tomcat上运行良好但是当试图在eclipse tomcat上运行它时，jsf组件没有被渲染，这是我的pom文件：

其他配置：

JSF被添加到项目方面
在部署程序集中添加了Maven依赖项

在服务器上运行应用程序时，我没有收到任何错误，实际上我看到日志意味着JSF已成功启动：

访问xhtml页面时，没有错误，但jsf和primefaces组件没有呈现，请告知如何解决此问题，谢谢。

Answer 1

我发现了这个问题，这很奇怪，在嵌入式tomcat上运行jar时我能够访问没有/ faces /前缀的xhtml页面但是在eclipse tomcat上我必须在xhtml页面之前添加/ faces /前缀工作正常。

在eclipse tomcat上运行springboot app时，不呈现JSF组件
