问在AWS弹性豆柄春季引导应用程序中创建名为“entityManagerFactory”的bean时出错

EN

我有一个简单的spring引导项目，使用spring starter jpa。该应用程序在我的本地运行良好。但是，当我使用弹性豆秆将应用程序部署到AWS时，它会产生以下错误：

org.springframework.beans.factory.BeanCreationException:错误创建名为“entityManagerFactory”的bean类路径资源init方法的org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class:调用失败；嵌套异常为org.hibernate.service.spi.ServiceException:无法创建请求的服务org.hibernate.engine.jdbc.env.spi.JdbcEnvironment.

我想是和包装罐子有关的东西，但是找不到解决办法。请帮帮忙。
