Java org.hibernate.engine.jdbc.spi.SqlExceptionHelper-函数；内；未找到；SQL语句

在这里，我试图找到我提供的范围内的所有实体。我的意思是，如果我给一个特定半径的圆，它必须显示所有的实体，它们的位置坐标都位于给定的圆内

我正在使用hibernate spatial来实现这一点。但是在JPA存储库接口中获取提到的错误

下面是

pom.xml

Address.java

@Entity
public class Address extends UUIDEntity2 implements HasEmailAddress, HasLocation {

    @Embedded
    @Column(columnDefinition = "point")
    private Location location;
    /*getters setters*/
}

location.java

@Entity
@NoArgsConstructor
public class Resource extends UUIDEntity2 implements IsResource {

    @Type(type = "org.hibernate.spatial.GeometryType")
    @OneToOne
    private Address address;

    /*getters setters*/
}

@Embeddable
@Value(staticConstructor = "of")
@RequiredArgsConstructor(staticName = "of")
public class Location implements Serializable {

    @Column(nullable = true)
    private Double lat;

    @Column(nullable = true)
    private Double lon;
}

测试

注意：此处未显示实体的所有属性。

参考资料如下：

听起来您没有为MySQL配置

SpatialDialect

。你能核实一下你有电话吗

hibernate.dialect=org.hibernate.spatial.dialect.mysql.MySQL56SpatialDialect

在

hibernate.properties

文件中

您还可以检查日志，查看Hibernate实际使用的方言。它的名称中应该有“Spatial”，以便hibernate可以使用Spatial函数。

我在application.properties文件中添加了它。但是日志说它使用的是“org.hibernate.dialoge.h2dialoge”。那么如何配置呢？

    @Inject
    private ResourceRepository resourceRepository;

    public Geometry createCircle(double x, double y, double radius) {
        GeometricShapeFactory shapeFactory = new GeometricShapeFactory();
        shapeFactory.setNumPoints(32);
        shapeFactory.setCentre(new Coordinate(x, y));
        shapeFactory.setSize(radius * 2);
        return shapeFactory.createCircle();
    }

    @Test
    public void geometry(){
        Geometry m = createCircle(0.0, 0.0, 5);
        List<Resource> resources = resourceRepository.test(m);
    }

hibernate.dialect=org.hibernate.spatial.dialect.mysql.MySQL56SpatialDialect

hibernate.dialect=org.hibernate.spatial.dialect.mysql.MySQL56SpatialDialect
