LocalContainerEntityManagerFactoryBean休眠配置bean在循环中初始化

Question

我在jpa.xml中声明了我的休眠实体管理器工厂，在hazelcast.xml中配置了hazecast，并且我设置了域模型，并且在其中实现了我的实体管理器工厂类的域模型项目中也存在相应的componentContext.xml。 。但是我的问题是面临的问题是我的componentContext.xml中的bean正在初始化（从hibernate.log中观察到）]

我的Web.xml仅配置了com.sun.faces.config.ConfigureListener侦听器。

我已经尝试调试多次，但是我无法弄清为什么初始化多次发生（就像在循环中一样）。任何指针都非常感谢！

我终于弄清楚了原因！在应用程序配置类中指定了一个额外的@ComponentScan批注，这导致触发了循环。
