带有primefaces的spring引导给出错误:java.lang.NoClassDefFoundError:org

Question

我是Spring boot的新手，我正在尝试使用STS IDE构建一个简单的带有素数的Spring boot项目。但是当我运行该程序时，我收到一个错误，如下所示：

2019-12-01 20:26:54.117 ERROR 5848 --- [           main] o.s.boot.SpringApplication               :

对于我的项目的pom.xml就是这样：

我按照这个网站的步骤操作：https://codenotfound.com/jsf-primefaces-example.html

Answer 1

使用的 Join Faces 的 4.0.1 版本依赖于 spring-boot-starter 2.1.1，而版本 2.2.1 已添加到 POM 中。这导致了java.lang.NoClassDefFoundError.

Answer 2

> 在 spring-boot-starter 2.1.1.RELEASE 上使用的 Join Faces 的 4.0.1 版

所以你可以使用 4.1.1 连接面作为弹簧引导启动器 2.2.1.发布 请检查下面的链接，你可以参考相应的spring-boot和joinfaces依赖组合。
