【问题讨论】：

您能出示您的实体吗？
如果可能的话，将整个代码分享到某个仓库中。
spring.jpa.hibernate.use-new-id-generator-mappings=false 在 application.properties 中试试这个

标签： java hibernate spring-boot maven

【解决方案1】：

发布此问题后，我尝试更改我的几个文件。所以最后我得到了答案。我可以通过更改 application.properties 文件来解决问题。

我之前的application.properties，

spring.datasource.username = root
spring.datasource.password = ****

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL57InnoDBDialect
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

spring.jpa.show-sql = false
spring.jpa.hibernate.ddl-auto=validate

The correct application.properties file,
```spring.datasource.url = jdbc:mysql://localhost:3306/Register
spring.datasource.username = root
spring.datasource.password = 1234

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL57InnoDBDialect
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

spring.jpa.show-sql = false
spring.jpa.hibernate.ddl-auto=update

【讨论】：

【解决方案2】：

我猜（因为您没有发布实体定义）您的“实体”类正在使用 @GeneratedValue() 而不指定要使用的序列（生成器名称）。因此，Hibernate 使用其默认名称：hibernate_sequence。

您可以提供序列名称作为 GeneratedValue 注释的一部分（通过生成器属性）

@GeneratedValue(strategy=SEQUENCE, generator="entity_sequence")

【讨论】：

【解决方案3】：

我不是 JPA 专家，但看起来当您运行项目 (mvn spring-boot:run) 时，它会连接到数据库并执行模式验证。 Schema 验证是确保项目中定义的实体确实可以映射到相应的数据库对象的过程：表、序列等。

由于没有表hibernate_sequence整个过程失败，因为spring boot/hibernate“认为”db不处于“运行”状态，不能和项目一起使用。

可以使用application.properties/yaml 中的属性spring.jpa.hibernate.ddl-auto=<value> 自定义此行为

可能的值是：

无
验证
更新
创建删除

以here 为例
