我正在使用主題中所述的框架。Hibernate-Spatial，JPA，Spring，MySQL 5.7（無法檢索點）
這是我的我的application.yml JPA屬性的一部分春天
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
我不知道這是否是觸發SpatialDialect爲MySQL5.7
我的實體法的正確方法對於點
@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;
}
我創建了一個類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);
}
}
隨着它完美的@Type（類型= 「com.iheartcity.apiapp.geometry.MySQLGeometryType」）
。但是，當我評論它時，運行代碼來檢索數據時，我開始出現錯誤。
這裏是個例外：

那麼就應該沒有指定工作一種。看看[GitHub上的這個測試]（https://github.com/hibernate/hibernate-orm/blob/master/documentation/src/test/java/org/hibernate/userguide/spatial/SpatialTest.java）。 –
