java - PostgreSQL:遇到无效的字节序标志值

Question

我正在尝试建立一个包含一些地理空间数据的 PostreSQL 表并进行一些空间查询。但我收到“遇到无效的字节序标志值”错误。我一直在互联网上寻找解决方案，但到目前为止还没有人完成这项工作。没有想法了。需要帮助。

场景是这样的

实体类:

import com.vividsolutions.jts.geom.Point;
import com.vividsolutions.jts.geom.Geometry;
import com.vividsolutions.jts.geom.LineString;
import com.vividsolutions.jts.geom.Polygon;

@Entity
public class PontodeInteresse implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE)
    private Long id;

    private String descricao;

    private Point ponto;

    private LineString linha;

    private Geometry geometry;

    private Polygon poligono;

    /* Getters and setters */

我可以从代码中插入一个多边形。一切似乎都很好:

public void criarGeometry () {
    PontodeInteresse ponto = new PontodeInteresse();

    GeometryFactory gf = new GeometryFactory();

    LinearRing shell = gf.createLinearRing(new Coordinate[] {
                                new Coordinate(-43.5552982, -22.8839067), new Coordinate(-43.5556591, -22.8838402),
                                new Coordinate(-43.5554786, -22.8829425), new Coordinate(-43.5555869, -22.8824438),
                                new Coordinate(-43.5552982, -22.8839067)});
    LinearRing[] holes = new LinearRing[0];
    Polygon polygon = gf.createPolygon(shell, holes);        
    ponto.setGeometry(polygon);
    colocar(ponto);
}

但是，当我尝试从方法 testar()(如下)运行简单的地理空间查询时，我收到“遇到无效的字节序标志值”错误。 我已经尝试使用 @Column 并设置地理类型，但没有成功。 如果我尝试从 PgAdmin 运行此查询，则会发生完全相同的错误:

从 pontodeinteresse 中选择 ST_AsGeoJSON(ST_GeomFromWKB(geometry));

   public void testar() {
        try {
            GeometryFactory gf = new GeometryFactory();
            Point pontoDentro = gf.createPoint( new Coordinate(-43.5658, -22.8722) );
            PontodeInteresse bairro = null;
            bairro = (PontodeInteresse) entityManager.createQuery("select p from PontodeInteresse p where contains(p.geometry, :ponto) = true").setParameter("ponto",pontoDentro).getSingleResult();
            if (bairro != null) {
                resultado = "OK";
            } else {
                resultado = "ERRO";    
            }//if
        } catch(Exception e) {
            System.out.println(e.getMessage());
        }//try
    }

请检查您的 hibernate 方言是否正确设置为 Postgis 方言。

这是一个使用 Spring boot application.properties 的例子:

spring.jpa.properties.hibernate.dialect=org.hibernate.spatial.dialect.postgis.PostgisDialect
