【问题描述】：
大家好，我正在使用带有 spring boot 和 spring data jpa 的 thymeleaf 3。但问题就在这里。当我尝试保存时，我从 Hibernate 收到此错误：
Hibernate: insert into consulta (medico_id) values (?)
Hibernate: insert into consulta_pacientes (consulta_id, pacientes_id) values (?, ?)

我已经尝试使用转换器，但没有正确锻炼。尝试查看此帖子* ...但也没有解决。

有什么建议吗？我现在有点迷路了。

【问题讨论】：
-
你能把
pct_id的代码贴出来吗？我假设这是某个类的属性。这可能有多种原因，但我正在考虑的两个原因是 1）错误地持久化 bean 以使其无法生成正确的 ID 或 2）不正确的 getter/setter -
确定...我会编辑原始帖子。
