Question

我正在尝试使用bean @Profiles声明来加载特定的hibernate设置，具体取决于我部署到的app服务器。

我在web.xml中注册了一个上下文配置文件初始化程序，并且还实现了ApplicationContextInitializer接口来执行我的app服务器逻辑。

问题在于，当我部署项目时，我收到以下错误：

找不到类型为[org.hibernate.SessionFactory]的匹配bean 依赖：预计至少有1个bean有资格成为autowire 这种依赖的候选人。依赖注释： {@ org.springframework.beans.factory.annotation.Autowired（所需=真）}

对我来说，在Spring自动连接剩余的bean之前，它看起来没有执行我的Profile检查（ApplicationContextInitilizer代码）。我的假设是否正确？我该如何纠正？
