springmvc只要注入service就报错,谁能帮我看看啊

public class testBatisController {

@Autowired
private UserService userService ;

@RequestMapping("/hello1")
public ModelAndView hello1()
return new ModelAndView("hello", "message",1);
}
我不注入那段service没事情一写注入就报这个错误:
No qualifying bean of type [net.spring.servoce.UserService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
