Spring 4 Rest problems

Question

I am trying to create a spring mvc rest app using spring 4 with the added restcontroller feature but i get an error inside the restcontrollerclass which i cant solve.

The error i get is this

I cannot import org.springframework.web.bind.annotation.RestController; to my restcontroller class it's marked with a red line underneath. I have got all the correct jars

Restcontroller

import org.springframework.web.bind.annotation.RequestMapping;

this is the line that is marked with a red line underneath
import org.springframework.web.bind.annotation.RestController;
if i remove the annotaion @Restcontroller the error disapears
so how do i import org.springframework.web.bind.annotation.RequestMapping; without      getting an error

[code] 
@RestController
@RequestMapping(value="/testrest")
public class RestController {

@RequestMapping("/greeting")
public String greeting(){
    return "hello";
}
}
[/code]

Answer 1

@RestController and your class name(RestController) are conflicting. You can't have the same name in as class. Change the name of your class file. it should work.

Answer 2

Include this in your Pom:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>${org.springframework.version}</version>
</dependency>

And let me know how you go.
