java - Hibernate实体模式@Table(schema ="")，获取表未找到异常

Question

我正在制作《你好，世界》!!!应用程序集成 Spring Web、Batch 和 Data JPA。定义实体并指定架构名称(@Table(schema="offline"))。出现未找到表异常，框架正在默认架构中查找表，但不在指定架构中查找表。不确定我错过了什么。

异常(exception):

由以下原因引起:java.sql.SQLSyntaxErrorException:表“localdb.people”不存在

您在网址中提到本地数据库是否有原因

spring.datasource.url=jdbc:mysql://localhost:3306/localdb

尝试将其更改为 spring.datasource.url=jdbc:mysql://localhost:3306/offline

在 MySQL 中，我相信数据库和模式之间没有真正的区别。因此，注释中提供的模式引用了模式，但不是 MySQL 中定义的模式。
