Java com.bookstore.demo.Services.UserSecurityService中的字段userRepository需要一个名为'；实体管理工厂&x27；那是找不到的

现在我正在使用SpringBoot开发在线书店web应用程序。我首先开始实现Spring安全性和一些数据库角色和服务。 但在第一次编译时，我发现了一些错误

我不确定是否在UserRepository中添加@Repository

UserSecurityService.java

        User user=userRepository.findByUsername(userName);

        if(null == user)
        {
            LOG.warn("Username {} Not Found",userName);
            throw new UsernameNotFoundException("Username"+userName+"Not Found");
        }


        return user;
    }
