import org.springframework.web.bind.annotation.RestController cannot be resolved

Question

I'm using Eclipse Kepler..I tried to use import org.springframework.web.bind.annotation.RestController But this import statement is not getting resolved I've added all the dependencies required for that..but restcontroller is not getting resolved..

package s;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class RestController {



@Autowired Bean bean;
@RequestMapping(value="/springAngularJS", method=RequestMethod.GET)

public @ResponseBody Bean getBean() {      
Bean bean=new Bean();
    bean.setUserName("savitha");

    bean.setAge("22");

    bean.setCompany("Infosys");

    bean.setDesignation("ApplicationDeveloper");

    return bean;
  }
  }

And my pom.xml is

Thanks in advance..

Answer 1

The problem is your class is named "RestController" and that conflicts with the actual RestController class used for the annotation. You just need to rename your class/file to something else like "DemoController" to avoid the class name conflict or specify the full path like @org.springframework.web.bind.annotation.RestController so it knows which one to use

Answer 2

I had the same issue i found the solution here. Add this dependency to the pom.xml

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>4.1.6.RELEASE</version>
    </dependency>

Answer 3

@RestController annotation since spring-web 4.0

Answer 4

Sometimes .jar files does not get downloaded via Maven properly. Please perform maven update on the project.

Answer 5

for a simple boot application,just check these dependencies in your pom.xml:

   <?xml version="1.0" encoding="UTF-8"?>

</project>

Answer 6

I was having similar problem using springboot, my spring version in Pom was

<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.1.RELEASE</version>

I changed the version to <version>1.5.9.RELEASE</version>

clean the project after that and import, that would work.
