Please make sure you have the correct packages to scan in your entity manager.
请确保您在实体管理器中扫描了正确的包。
entityManagerFactory.setPackagesToScan(
env.getProperty("entitymanager.packagesToScan")
);
are you sure the correct path has been set here. Not sure what entity manger is and are you setting the path to scan
你确定这里设置了正确的路径吗?不确定实体管理器是什么,您是否设置了扫描路径
回答by TanvirChowdhury
if your application if there is any baseClass defined then try to use
如果您的应用程序定义了任何基类,则尝试使用
entityManagerFactoryBean.setPackagesToScan(new String[]{BaseEntity.class.getPackage().getName()});
