大家好，我使用带有弹簧靴和弹簧数据jpa的百日咳3。但这是问题所在。当我尝试保存时，我从Hibernate得到了这个错误：
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。试图查看这些帖子* ...但是也没有解决。

答案 0 :(得分：0)
问题解决了。看来，如果更改hibernate映射，则必须重新创建数据库。我做到了，问题解决了。
