java - Spring寻找我没有使用java.sql.SQLSyntaxErrorException : Table 'meetings.meeting' doesn't exist创建的表

Question

为什么我运行此应用后在控制台中出现这些错误？

java.sql.SQLSyntaxErrorException: Table 'meetings.meeting' doesn't exist

我尝试使用的现有表在名为 meetings 的 MySQL 模式中称为 meetings_list。为什么要查找表“meetings.meeting”？

Answer 1

根据您的 DDL，您的表名称是 meetings_list。然而，您的实体 bean 的名称是 Meeting，这就是 hibernate 尝试将其映射到一个不存在的名为 meeting 的表的原因。

将实体类的名称更改为

@Entity
public class MeetingList {
...

或者像这样使用@Table注释

@Entity
@Table(name = "meeting_list")
public class MeetingList {
...
