Question

我正在研究《 Hello，World》！集成Spring Web，Batch和Data JPA的应用程序。定义了实体并指定了架构名称（ @Table（schema =“ offline”））。获取未找到表异常，框架正在默认模式中查找表，但不在指定模式中查找表。不确定我缺少什么。

例外：

原因：java.sql.SQLSyntaxErrorException：表'localdb.people'不存在

Answer 1

您为什么在网址中提到本地数据库

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，我相信数据库和架构之间没有真正的区别。因此，注释中提供的架构引用的是架构，但未引用MySQL中定义的架构。

Answer 2

尝试从更改连接字符串：

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

收件人：

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

Answer 3

休眠实体架构@Table（schema =“ <schema-name>”），未找到表异常
