您缺少

 ＆LT; MVC：注解驱动/＆GT;
 

在你的配置分配器 - servlet.xml中

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).

The error I am getting is 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.

解决方案

You are missing

<mvc:annotation-driven />

in your config dispatcher-servlet.xml
