Question

我正试图从eclipse打开index.html。但我得到了这个错误：

javax.servlet.ServletException：资源配置类无法加载com.sensorhound.things.rest.ThingsApplication。

我正在使用java EE框架。

以前，我使用Node.js假服务器编写我的前端代码。然后我在eclipse中创建了一个maven项目来编写我的后端代码。在我写完后端代码之前，我没有将我的前端代码移到这个项目中。

我在开始使用Wildfly服务器和Cassandra数据库之前测试我的前端代码做了什么，然后我将在我的后端项目目录下进行mvn wildfly：deploy。然后我将转到前端代码文件夹并在浏览器中打开index.html。它工作正常。

现在我需要完成我的项目，所以我将我的前端代码复制到

的src /主/ web应用

目录，并更新我的项目。

但是当我尝试从eclipse打开index.html时。它给了我这个错误。

有关更多参考，请参阅我的web.xml：

我通过在web.xml中删除与servlet相关的标记来解决这个问题。这些是我的同事在使用jetty服务器时添加的代码。
