我正在配置我的 Spring MVC 项目，部署在 Intellij Idea 上的 Tomcat 本地服务器 (tomcat 9) 上。请查看代码并帮助我确定我缺少的内容。 我在代码中找不到任何错误。
一流的房子

所以我有一个问题。应用程序知道这些表，但在表库上显示错误。 (没有这个表一切都可以，只有这个表“坏了”，我不知道为什么)

最佳答案
由 org.postgresql.util.PSQLException 引起:ОШИБКА: столбец t1.tgconstrname не существует
号码:113
表中不存在列 tgconstrname。
...这听起来像是“驱动程序冲突”(< 9.0)(请参阅: PostgreSQL 9.0 error: column t.tgisconstraint does not exist ，特别是 Quassnoi's answer )
和this (comment)听起来很有帮助而且很最新。
