我得到這個錯誤豆：

ERROR org.springframework.web.context.ContextLoader - Context initialization failed 
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in file [C:\Users\Tecnico1\Documents\workspace-sts-3.2.0.RELEASE\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\marshall\WEB-INF\classes\META-INF\spring\applicationContext.xml]: Cannot resolve reference to bean 'entityManagerFactory' while setting bean property 'entityManagerFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in file [C:\Users\Tecnico1\Documents\workspace-sts-3.2.0.RELEASE\.metadata\.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\marshall\WEB-INF\classes\META-INF\spring\applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: @OneToOne or @ManyToOne on

我是一個初學者，我不發現錯誤...也許我有重複的罐子......在那種情況...我必須去掉什麼罐子？

謝謝！
