启动应用时报以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: No identifier specified for entity: com.ipcatfish.crowdfunding.domain.CrowdFund

原因是实体类id的注解@Id引入的包是Spring的，需要改成

import javax.persistence.Id;
