I am trying to use @RestController in a spring application but I  cannot find the import; I keep reading on the internet that I should have a dependency for spring-webmvc in the pom, but I already have one. My pom is

I also added something I found in an internet page about @RestController

I have been exploring the internet for several days, bu I still haven't found the solution.

you need to add spring-web dependency

<!-- https://mvnrepository.com/artifact/org.springframework/spring-web -->
<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-web</artifactId>
   <version>5.1.0.RELEASE</version>
</dependency>

<spring.version>3.1.2.RELEASE</spring.version>

RestController annotation didn't appear until (I think) Spring 4.

You need to upgrade to a newer version of Spring.

Thank you Tushar Goel; I changed <spring.version>3.1.2.RELEASE</spring.version> to <spring.version>5.1.0.RELEASE</spring.version> and it is working fine.

Something incredible is happening. When I run the application I am getting 404 error "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists." . ngly, the problem hapens before I update the project with Maven. The problem happens with Pivota tc Server, or with a new server. I have had this problem before for several days and I haven't been able to find a solution. Of course, if I revert the change in <spring.version> the problem disapears.
On the other hand, if I only change the version for spring-web (which was my original problem) I am getting the errors
Description Resource Path Location Type
The project was not built since its build path is incomplete. Cannot find the class file for org.springframework.context.annotation.AnnotationConfigRegistry. Fix the build path then try building this project Spring Data Chapter-2 Unknown Java Problem

The problem with "The origin server did not find a current representation for the target resource or is not willing to disclose that one exists." still continues.
 
You can't have everything. Where would you put it?
