@Autowired在RESTFul Web服务请求中不起作用

Question

I'm using RESTFul webservice with spring hibernate project.I call a webservice with a method but i can't call the @service layer UserService bean which is null. here my webservice Class.

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 !!!!!!!!";

    }
}

The @Autowired annotation is not working .please provide the solution

Answer 1

I had this problem. After checking very things, i see a problem in a class that i define as a bean. some of classes have a special annotation or method that cause spring fail when create bean for that class.
