spring annotation not working

Question

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.

Answer 1

You are missing

<mvc:annotation-driven />

in your config dispatcher-servlet.xml

See here for more info

Answer 2

您在控制器中映射了路径/index.do ，因此您必须使用以下 URL 访问它： http://localhost/av/index.do

Answer 3

<mvc:annotation-driven/>将解决您的问题。

Answer 4

Please try this

<bean 
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> 

add an entry in dispatcher-servlet.xml

Answer 5

在您的 disapatcher-servlet.xml 中，添加<mvc:annotation-driven/>以启用注释驱动处理程序映射。

Answer 6

Try to go through one of my tutorials:

Creation of a simple Controller with java-based config

I hope I will get success with it
