问题：

无法使用Spring Boot REST存储库在H2 DB中创建记录

储仲渊
2023-03-14

我无法通过Postman使用POST创建具有以下有效载荷的资源。所有其他方法GET、PUT和DELETE都运行良好。我使用Spring Data REST API自动创建endpoint。

如何使用POST创建资源？

终点：

http://localhost:8080/client

有效载荷：

{
    "clientName": "Walmart",
    "active": "Y"
}

例外情况：

解决办法是：

CREATE SEQUENCE CLIENT_SEQUENCE_ID START WITH (select max(ID) + 1 from CLIENT);

（这允许您使用静态值预填充CLIENT，并相应地初始化序列）

在爪哇

@Id
@SequenceGenerator(name= "CLIENT_SEQUENCE", sequenceName = "CLIENT_SEQUENCE_ID", initialValue=1, allocationSize = 1)
@GeneratedValue(strategy=GenerationType.AUTO, generator="CLIENT_SEQUENCE")
private Long id;

请按照上面的指示。
