Java Hibernate Spatial、JPA、Spring、MySQL 5.7（无法检索点）

我正在使用主题中所述的框架

这是我在application.yml for spring中jpa属性的一部分

jpa:
  database: mysql
  hibernate:
    naming:
      physical-strategy: org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl 
  properties:
    hibernate:
      dialect: org.hibernate.spatial.dialect.mysql.MySQL56InnoDBSpatialDialect
      globally_quoted_identifiers: true
  show-sql: true

我不确定这是否是为MySQL5.7触发SpatialDialect的正确方法

点的实体方法

@Type(type = "com.iheartcity.apiapp.geometry.MySQLGeometryType")
@Column(name = "location", nullable = false)
public Point getLocation() {
    return this.location;
}
public void setLocation(Point location) {
    this.location = location;
}

我创建了一个类MySQLGeometryType.java：

package com.iheartcity.apiapp.geometry;

import org.hibernate.spatial.JTSGeometryType;
import org.hibernate.spatial.dialect.mysql.MySQLGeometryTypeDescriptor;

public class MySQLGeometryType extends JTSGeometryType {

    public MySQLGeometryType() {
        super(MySQLGeometryTypeDescriptor.INSTANCE);
    }
}

使用@Type（Type=“com.iheartcity.apiapp.geometry.MySQLGeometryType”）

它工作得很好。然而，当我对它进行注释时，我开始在运行代码检索数据时出错

例外情况如下：

您可以使用

com.livitsolutions.jts.geom.Point

类，然后不需要显式指定@Type

---

在上查看此示例。

实际解决方案是删除

@Type

并使用

@Column（name=“location”，nullable=false，columnDefinition=“Point”）

---

请注意，这是针对MySQL的，将正确的方言添加到应用程序中。properties为我修复了此错误：

spring.jpa.properties.hibernate.dialect=org.hibernate.spatial.dialect.mysql.MySQL56InnoDBSpatialDialect

---

那么它应该在不指定类型的情况下工作。看看。@Vlad，高度重视你在这个论坛上的意见。但请务必在Hibernate 5中登记。如果我们不提供columnDefinition=“POINT”，它根本不会创建POINT类型的mysql字段。与Geometry类似的情况在我的案例中，我必须将Hibernate Spatial（

'org.Hibernate:Hibernate Spatial:5.0.12.Final'

）添加到我的项目中，然后在Java JPA实体中，将

点

字段的类型设置为

com.livitalSolutions.jts.geom.P
