java - 无法使用 Hibernate Spatial 将 Point 插入 mysql 数据库

Question

我正在使用来自 docker image 的 mysql 服务器mysql:8.0.16。它有 MySQL InnoDB 版本8.0.16。

我正在尝试使用hibernate框架将具有 Point 变量的实体插入到数据库中。我总是收到同样的错误：

Cannot get geometry object from data you send to the GEOMETRY field

当我尝试将Booking类型插入数据库时​​出现此错误（定义Booking如下）。Bookings 有 2 个Point由 @Column 注释的类型字段，其 ColumnDefinition 等于geometry(POINT, 0)。

我正在使用数据库优先的方法。Hibernate 本身不会创建任何表。

我com.vividsolutions.jts.geom.Point用来存储我的 2 点。

我调查了hibernate正在尝试执行这个sql：

insert into Bookings (CarId, DropPosition, EndDateTime, PickupPosition, StartDateTime, UserId) values (13, x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x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

我感觉插入点的数据太大了。我不完全确定是否将正确的东西插入数据库。

为预订创建脚本：

CREATE TABLE Bookings (
-- removed other fields for clarity
    PickupPosition POINT NOT NULL,
    DropPosition POINT,

)

Booking.java

@Entity
@Table( name = "Bookings" )
public class Booking {
    @Column(name = "PickupPosition", nullable = false, columnDefinition = "geometry(POINT, 0)")
    @NotNull
    private Point pickupPosition;


    @Column(name = "DropPosition", columnDefinition = "geometry(POINT, 0)")
    private Point dropPosition;

// removed other fields/methods/getters/setters for clarity
}

我尝试了什么：

• 设置不同的 MySQL 空间方言
  • 没有帮助
• 从 Column 注释中删除 columnDefinition
  • 我收到以下错误Schema-validation: wrong column type encountered in column [DropPosition] in table [Bookings]; found [geometry (Types#BINARY)], but expecting [tinyblob (Types#VARBINARY)]
• 在 MySQL 脚本中将类型从点更改为几何
  • 没有帮助 - 同样的错误
• 在 Java 代码中将类型从点更改为几何
  • 没有帮助 - 同样的错误
• 试图将 ColumnDefinition 更改为 Point
  • 我在 sessionFactory 的构建过程中收到了这个错误Schema-validation: wrong column type encountered in column [DropPosition] in table [Bookings]; found [geometry (Types#BINARY)], but expecting [point (Types#VARBINARY)]

--

我阅读了大量关于堆栈溢出的问题，但我没有发现任何与我完全相同的问题。

我只想将 Point 插入数据库。就这样。

Answer 1

事实证明，我的问题的解决方案是使用org.locationtech.jts.geom.Point;而不是com.vividsolutions.jts.geom.Point.
