在尝试创建private UserService userService;豆子时，使用 spring 自动布线似乎有问题。 作为参考，我已经经历了这些。
自动连线依赖项的注入失败;
上下文：组件扫描"未绑定
尝试访问 dao bean 时注入自动连线依赖项失败
这些并不能解决我的问题，因为我的代码中已经有了这些。 但是从错误日志来看，可能还存在与创建休眠模板相关的问题，因为它位于嵌套的错误列表中。我仍在尝试很多时间，但没有得到任何输出。谁能解释为什么它显示注射失败？因为我已经遵守了规则，并且上面的一些参考并不能解决我的问题。谢谢。
为什么你有这样的东西？
@Service("用户服务"(
只需改用@Service即可。
@Component("用户DAO"(也是如此 把它换成@Compoment甚至更好的@Repository因为它是道类
