Question

我遇到的第一个错误

无效操作：SQL命令 “如果存在hibernate_sequence，则丢弃序列” 不支持

在例外情况下，我看到以下内容。我假设我必须更改hibernate_sequence中索引递增的方式。

Caused by: com.amazon.support.exceptions.ErrorException: [Amazon](500310) Invalid operation: SQL command "create sequence hibernate_sequence start 1 increment 1" not supported.;
    ... 49 common frames omitted
2019-10-07 14:02:30,237 WARN  [main] org.hibernate.tool.schema.internal.ExceptionHandlerLoggedImpl: GenerationTarget encountered exception accepting command : Error executing DDL "create sequence hibernate_sequence start 1 increment 1" via JDBC Statement
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "create sequence hibernate_sequence start 1 increment 1" via JDBC Statement

在构建Java Spring Boot应用程序时，寻求连接并创建新的redshift数据库集群V1.0.10393。

POM和属性文件应该是什么样的？我正在从工作中的PostgreSQL数据库过渡到redshift。

当前属性

Answer 1

由于使用生成的ID，我正在发生错误

except ImportError as e:

我已将它们替换为@EmbeddedId。以及命名索引被删除。
