我创建了简单的 spring MVC 控制器，当我尝试执行时出现错误。
错误信息：
org.springframework.beans.factory.CannotLoadBeanCl assException：找不到在 ServletContext 资源 [/WEB-INF/springapp-servlet.xml] 中定义的名称为“Redirect.jsp”的 bean 的类 [SpringApp.web.java.HelloController]；嵌套异常是 java.lang.ClassNotFoundException: SpringApp.web.java.HelloController
这是我的应用程序结构。
