Spring mvc Java based Configuration not working. Console display no error but my jsp page is not showing
提问by Kharoud
Hello i am converting my simple demo project from bean configuration to pure java based configuration. Bean configuration works fine creating tables and all. But my java configuration is not displaying any pages. I solved many errors bur now console shows no error specifying the problem. here's my code please find whats wrong, or have i missed anything in the configuration. I am new to spring and fairly new to java based configuration. These are the sites from which i took code.
您好，我正在将我的简单演示项目从 bean 配置转换为纯基于 Java 的配置。 Bean 配置可以很好地创建表和所有内容。但是我的 java 配置没有显示任何页面。我解决了很多错误，现在控制台没有显示指定问题的错误。这是我的代码，请找出问题所在，或者我错过了配置中的任何内容。我是 spring 的新手，对基于 Java 的配置相当陌生。这些是我从中获取代码的站点。

Myindex.jsp file is in WEB-INF/views folder under webapp folder
Myindex.jsp 文件在 webapp 文件夹下的 WEB-INF/views 文件夹中
The views were properly resolved with bean configuration.

Thank you for your answers. I found the problem. When i wrote @ComponentScan on top of my MvcConfiguration class it worked and pages are displaying.
谢谢您的回答。我发现了问题。当我在 MvcConfiguration 类的顶部编写 @ComponentScan 时，它可以工作并且页面正在显示。
