Question

我尝试了很多可能性，但没有为我工作。一世有一个带有maven和eclipse的spring mvc应用程序作为构建工具。在我的应用程序我配置了Context Load监听器和Dispatcher 调度程序servlet中的servlet我配置我的spring 配置文件，但它显示文件未找到异常 WEB-INF / applicationContext.xml中。但我没有我的应用程序中的applicationContext.xml文件。我需要两者 ContextLoadListener和dispatcher servlet。如何解决这个问题。这是我的Web.xml文件

我运行网址时遇到的错误是http://localhost:8080/sdnext/ 我得到的输出是错误页面404说“请求资源不可用（/ sdnext /）

在控制台中我收到错误
