我试图用Sping Boot 创建一个应用程序，但我不知道我做错了什么。我相信它源于我的实体设计，但我不知道如何修复它。我有两个实体，我想被链接到。飞机实体必须与差异实体有一对多的关系。在我的存储库中，我使用JPA存储库和find-all方法。
当使用postman发送一个get请求来检索所有飞机对象时，我收到了这个错误。

这可能是因为该表不存在于数据库的模式中。
为了解决这个问题，您可以在application.properties文件中设置此属性

spring.jpa.hibernate.ddl-auto= update

字符串
如果表不存在，则此属性将创建表，或者如果表存在，则更改表。
希望问题得到解决。

消息很清楚：你没有一个表/视图称为'飞机'在模式'飞机'，Peraphs表存在于'公共'模式？
