您能告诉我如何从控制台修复此异常吗？
org.postgresql.util.PSQLException：错误：关系“xxxx”不存在
此异常适用于我的项目中的某些表，我不知道为什么。应用程序正常，没有任何问题。我有资源导入脚本dml和表也被填充。
以下是我的示例实现表：
@MappedSuperclass
public class Abstract {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID", columnDefinition = "serial")
private Long id;
@Column(name = "CREATED_ON", nullable = false, columnDefinition = "TIMESTAMP")
private LocalDateTime createdOn;
}
和抽象类：
Hibernate: alter table users_contacts drop constraint FK__USERS__USERS__USER_ID
