我无法插入任何行，因为id始终为null。有人知道如何解决生成此ID的问题吗？
如果需要更多数据，请随时编写，只要它可以帮助我解决此问题！
应用程序是使用JHipster v.5.8.1生成的
答案 0 :(得分：1)
在数据库中检查如何创建ID列。它有身份吗？
create table DogEntity (id bigint generated by default as identity (start with 1), ...
答案 1 :(得分：0)
已解决：
应用程序使用Liquidbase，并且JHipster在实体中生成了错误的注释。更改日志中的Liquidbase的autoincrement属性设置为false并声明了序列生成器。
我将所有changelogs id的autoincrement属性设置为true，并摆脱了序列构建器。当Liquidbase创建新数据库时，实体开始工作。
