Question

我想在mysql和spring boot中使用hibernate spatial。我试过但失败了。 application.properties文件在下面给出

df2.groupby(['Survived', 'Pclass']).size().unstack().plot(kind='bar', stacked=True)

但是我在部署时遇到了异常

spring.datasource.url=jdbc:mysql://localhost:3306/tour_management
spring.datasource.username=root
spring.datasource.password=admin
endpoints.actuator.enabled=true
endpoints.info.enabled=true

spring.jpa.properties.hibernate.dialect = 
org.hibernate.spatial.dialect.mysql.MySQLSpatial5InnoDBDialect
spring.jpa.database-platform = 
org.hibernate.spatial.dialect.mysql.MySQLSpatial5InnoDBDialect



@Data
@Entity(name = "Place")
public class PlaceEntity extends BaseEntity {
@Id
@GeneratedValue
@Column(name = "ID")
private long id;
@Column(name = "NAME")
private String name;
@Column(name = "CODE")
private String code;
@Column(name = "LONGITUDE")
private Double longitude;
@Column(name = "LATITUDE")
private Double latitude;

@Column(name = "LOCATION",columnDefinition = "geometry(Point,4326)")
private Point location;
}

引起：org.hibernate.boot.registry.selector.spi.StrategySelectionException：无法将名称[org.hibernate.spatial.dialect.mysql.MySQLSpatial5InnoDBDialect]解析为策略[org.hibernate.dialect.Dialect] 在org.hibernate.boot.registry.selector.internal.StrategySelectorImpl.selectStrategyImplementor（StrategySelectorImpl.java:113）〜[hibernate-core-5.0.12.Final.jar：5.0.12.Final]

是否存在与版本相关的问题????

如果我们在运行时匹配您的异常：

引起： org.hibernate.boot.registry.selector.spi.StrategySelectionException：无法解析名称 [org.hibernate.spatial.dialect.mysql.MySQLSpatial5InnoDBDialect] as 策略[org.hibernate.dialect.Dialect] at org.hibernate.boot.registry.selector.internal.StrategySelectorImpl.selectStrategyImplementor（StrategySelectorImpl.java:113）〜[冬眠核-5.0.12.Final.jar：5.0.12.Final]

源代码为StrategySelectorImpl：

@Override
    @SuppressWarnings("unchecked")
    public <T> Class<? extends T> selectStrategyImplementor(Class<T> strategy, String name) {
        final Map<String,Class> namedStrategyImplementorMap = namedStrategyImplementorByStrategyMap.get( strategy );
        if ( namedStrategyImplementorMap != null ) {
            final Class registered = namedStrategyImplementorMap.get( name );
            if ( registered != null ) {
                return (Class<T>) registered;
            }
        }

        try {
            return classLoaderService.classForName( name );
        }
        catch (ClassLoadingException e) {
            throw new StrategySelectionException(
                    "Unable to resolve name [" + name + "] as strategy [" + strategy.getName() + "]"
            );
        }
    }

我们知道类加载器无法加载org.hibernate.spatial.dialect.mysql.MySQLSpatial5InnoDBDialect类。它可能不在类路径中。

我想你应该添加与你的Hibernate版本匹配的hibernate空间依赖。

Hibernate-spatial jpa与myql和Spring boot 1.5.7无法正常工作
