spring annotation not working
提问by jaxkodex
I am starting with Spring Framework and want to do a HelloWorld with annotatios, I've made it work creating a controller and a view, basic hello work I guess; however, I want to use annotatios since I can not use SimpleFormController any more (deprecated).
我从 Spring Framework 开始，想用 annotatios 做一个 HelloWorld，我已经让它工作了，创建了一个控制器和一个视图，我猜是基本的 hello 工作；但是，我想使用 annotatios，因为我不能再使用 SimpleFormController（已弃用）。
The error I am getting is Estado HTTP 404 - /av/index.jsp
我得到的错误是 Estado HTTP 404 - /av/index.jsp
I am using Netbeans and I am basing the example on the basic template It provides. I have the following files, I am pretty sure it is a missconfiguration but I can't find anything that would help me so far. Thanks in advance.
我正在使用 Netbeans，我的示例基于它提供的基本模板。我有以下文件，我很确定这是一个错误配置，但到目前为止我找不到任何对我有帮助的东西。提前致谢。

You mapped the path /index.doin your controller, so you have to access it with the following url: http://localhost/av/index.do
您/index.do在控制器中映射了路径，因此您必须使用以下 URL 访问它：http://localhost/av/index.do
