无法使用 Spring Boot REST 存储库在 H2 DB 中创建记录

Question

我无法通过邮递员使用 POST 创建具有以下有效负载的资源。所有其他方法GET，PUT和DELETE都可以正常工作。我已经使用Spring Data REST API自动创建端点。

如何使用 POST 创建资源？

端点：

http://localhost:8080/client

有效载荷：

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

例外：

private String active;
}

Answer 1

解决方案是：

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(

和爪哇

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

请按照上述说明进行操作。
