@Autowired没有在RESTFul Web服务请求中工作

标签： java spring web-services hibernate rest

我正在使用带有spring hibernate项目的RESTFul webservice。我使用方法调用webservice，但我不能调用@service层UserService bean为null。这是我的webservice类。

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.context.support.SpringBeanAutowiringSupport;
import com.ontag.circa.domain.User;
import com.ontag.circa.service.UserService;`enter code here`

@Component
@Path("/users")
@WebService
public class UserServiceWS extends SpringBeanAutowiringSupport {

    @Autowired
    UserService userService;

    User user=new User();

    @POST
    @Consumes(MediaType.APPLICATION_FORM_URLENCODED)
    @Produces(MediaType.APPLICATION_JSON)
    @WebMethod
    public String addUserDeatails(MultivaluedMap<String, String> userParams) {

            user.setUsername(userParams.getFirst("username"));                  
            user.setGcmid(userParams.getFirst("gcmid"));
            user.setPassword(userParams.getFirst("password"));

            userService.addUserDeatails(user);

        return "Sucesss !!!!!!!!";

    }
}

@Autowired注释不起作用。请提供解决方案

////这是我的界面

   public interface UserService {

        public String addUserDeatails(User user);
        public String getsomevalue(String mess);

    }

    // this is my implementation class
    import javax.transaction.Transactional;
    import org.hibernate.Session;
    import org.hibernate.SessionFactory;
    import org.hibernate.Transaction;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Repository;
    import com.ontag.circa.domain.User;

    @Repository
    public class UserDaoImpl  implements UserDao  {

        @Autowired
        SessionFactory sessionFactory;

        @Override
        @Transactional
        public String addUserDeatails(User user)

    }

我有这个问题。在检查了很多东西之后，我在类中定义了一个问题，我定义为bean。一些类有一个特殊的注释或方法，当为该类创建bean时会导致spring失败。
