spring - import org.springframework.web.bind.annotation.RestController 无法解析

Question

我正在使用 Eclipse Kepler ..我尝试使用
导入 org.springframework.web.bind.annotation.RestController
但是这个导入语句没有得到解决
我已经添加了所需的所有依赖项..但是 restcontroller 没有得到解决..

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;
  }
  }
