您的实体类似乎是正确的，但请再次验证，以检查是否存在任何不一致。

**注意：**我猜你通过controller创建和发送数据到DB的方式是错误的。控制器逻辑看起来可疑。请验证您的控制器和实体。

让我展示一下我是如何测试它的。我从一开始就在我的系统上设置Oracle DB。

帮助您达成解决方案的步骤：
注意：我使用Oracle DB 23 c、MacOS和JDK 17.0.8来证明我的观点。
**您可以使用任何版本的Oracle DB。**对于Windows，我猜Oracle DB安装程序是存在的。因此，您可以跳过基于VM的设置。

Oracle不支持MacOS的安装程序。所以，出于这个原因，我不得不这样做。
对于MacOS方式：

• 首先在系统上安装Oracle Virtual Box。您可以从基于操作系统的here下载。
• 然后，从here官方网站下载安装Oracle Database 23 c Free - Developer Release VirtualBox Appliance（.vba）。

此.vba文件提供预配置的Oracle软件供您使用。
上述虚拟机包含：

1. Oracle Linux 8.7
2. Oracle Database 23.2 Free - Developer Release for Linux x86-64
3. Oracle REST Data Services 23.1
4. Oracle SQLcl 23.1
5. Oracle APEX 22.2

• 您必须按照安装视频here从数据库之星星将帮助您设置。
• 完成此操作后，从here将Oracle SQL Developer安装到系统上。
• 同时启动包含托管在Linux上的Oracle DB的VM。它也将启动Oracle DB。
• 启动Oracle SQL Developer并连接到VM oracle DB，然后测试连接是否成功。

对于Oracle 23 c，默认用户为-hr，密码为-oracle，可插入数据库为-freepdb1
现在，您已经完成了DB设置。
现在，进入codebase：
我已经创建了一个示例Sping Boot 项目，名称为“demo”，结构如下。

只要我启动应用程序，它就会在oracle数据库中创建表'MY_GEO'，因为这个属性spring.jpa.hibernate.ddl-auto=create。
单击SQL Developer中的刷新按钮以带来新创建的表。

表格列：

现在，我有一个端点来保存数据。所以，只要我点击url -http://localhost:8080/save
它成功地保存了数据，没有任何问题。

MyGeo(id=ID, shape=POLYGON ((0 1, 2 5, 2 7, 0 7, 0 1)))

我的数据库更新了我发送的数据：

仅此而已

尝试在application.properties中添加

spring.jpa.properties.hibernate.dialect = org.hibernate.spatial.dialect.oracle.OracleSpatial10gDialect

如果未指定Entity by Hibernate的Map，则shape字段的空间类型。因此，您需要确保Polygon是不适合在Geometry点上使用的类型。因此，您使用Geometry而不是Polgon，并通过执行以下代码定义您的类型，以便Hibernate可以匹配org.hibernate.spatial.GeometryTpe：

@Column(name = "shape", columnDefinition = "MDSYS.SDO_GEOMETRY")
    @Type(type = "org.hibernate.spatial.GeometryType")
    private Geometry shape;

Geometry类，可以从com.vividsolutions.jts.geom.Geometry使用。
