我正在构建一个基于 MVC 架构的简单 Web 应用程序。我有一个带有 HTML 表单的小型 JSP 页面。表单数据被转发到 servlet，然后委托给 Controller 类。
单击表单上的提交时，我收到 HTTP Status 500 - 由“UnsatisfiedResolutionException”引起的错误。容器好像找不到Controller？
文件Context.xml作为我的数据源。我正在使用 apache tomee webprofile 1.7.4。
错误：
type Exception report
message Error instantiating servlet class a1.DispatcherServlet
description The server encountered an internal error that prevented it from fulfilling this request.
