Java 启动时出错：org.springframework.beans.factory.BeanCreationException:创建名为的bean时出错

我是一个春天+冬眠的新手。我正在尝试使用Spring boot App部署应用程序，一切正常，直到出现以下异常：

问题在于没有加载applicationContext.xml，这就是自动配置启动并尝试初始化嵌入式数据库的原因。因此，要导入配置文件，请在具有@configuration的类中使用

@ImportResource("classpath:path/to/applicationContext.xml")

---

如果这是一个典型的spring boot应用程序，请添加

应用程序

或任何您拥有的主条目您确定要注册

applicationContext.xml

？

@ImportResource("classpath:path/to/applicationContext.xml")
