解決方法:
プロバイダコード:

@Service(version = "1.0.0") //         
public class OrderServiceImpl implements OrderService {
     

    public Order getUserOrder(Integer id) {
     
        Order order = new Order();
        order.setUid(id);
        order.setOrderNo("202020202020100");
        order.setContent("      ");
        return order;
    }

}

消費者コード:

@Service(version = "1.0.0")
@Component
public class UserServiceImpl implements UserService {
     

	@Reference(version = "1.0.0") //    
    //    @Reference
    OrderService orderService;

    public User selectUserById(Integer id) {
     
        Order userOrder = orderService.getUserOrder(id);
        User user = new User();
        user.setUid(id);
        user.setAge(1);
        user.setName("wudner");
        user.setEmail("[email protected]");
        user.setOrder(userOrder);

        return user;
    }
}

消費者のReference注釈の属性versionは、プロバイダに対応する@Service(version = "1.0.0")を必要とする
