Я пытаюсь сохранить географические данные в БД, для этого я учусь использовать hibernate-пространственный, но у меня возникают некоторые проблемы с фабрикой сеансов.
Проблема возникает, когда всущность, которую я использую @Type (type = "org.hibernate.spatial.GeometryType"), класс Hibernate Util завершается ошибкой.
Это DAO:
@Repository
public class GeometryDAO implements IGeometryDAO {
Session session;
Transaction tx;
@PersistenceContext
private EntityManager entityManager;
@Override
public void registerPoint(String userId, String point) {
startsOperation();
Points pointEntity =new Points();
pointEntity.setPointName("test");
pointEntity.setUserId("12345");
pointEntity.setPoint((Point) wktToGeometry(point));
session.save(pointEntity);
tx.commit();
session.close();
}
public Object getPoints() {
StringBuilder queryStB = new StringBuilder();
queryStB.append("SELECT * FROM Points");
String queryString = queryStB.toString();
Query query = entityManager.createNativeQuery(queryString);
return query.getResultList();
}
private void startsOperation() throws HibernateException {
session = HibernateUtil.getSessionFactory().openSession();
tx = session.beginTransaction();
}
private Geometry wktToGeometry(String wktPoint) {
WKTReader fromText = new WKTReader();
Geometry geom = null;
try {
geom = fromText.read(wktPoint);
} catch (ParseException e) {
throw new RuntimeException("Not a WKT string:" + wktPoint);
}
return geom;
}
}
Это HibernateUtilКласс:
import java.util.HashMap;
import java.util.Map;
import org.hibernate.SessionFactory;
import org.hibernate.boot.Metadata;
import org.hibernate.boot.MetadataSources;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import com.gisapp.models.entity.Points;
import com.gisapp.models.entity.User;
public class HibernateUtil {
private static StandardServiceRegistry registry;
private static SessionFactory sessionFactory;
public static SessionFactory getSessionFactory() {
if (sessionFactory == null) {
try {
StandardServiceRegistryBuilder registryBuilder =
new StandardServiceRegistryBuilder();
Map<String, String> settings = new HashMap<>();
settings.put("hibernate.connection.driver_class", "org.postgresql.Driver");
settings.put("hibernate.connection.url", "jdbc:postgresql://localhost:5432/postgres");
settings.put("hibernate.connection.username", "postgres");
settings.put("hibernate.connection.password", "admin");
settings.put("hibernate.show_sql", "true");
settings.put("hibernate.hbm2ddl.auto", "update");
settings.put("hibernate.dialect", "org.hibernate.spatial.dialect.postgis.PostgisDialect");
registryBuilder.applySettings(settings);
registry = registryBuilder.build();
MetadataSources sources = new MetadataSources(registry);
sources = new MetadataSources(registry)
.addAnnotatedClass(Points.class).addAnnotatedClass(Points.class);
Metadata metadata = sources.getMetadataBuilder().build();
sessionFactory = metadata.getSessionFactoryBuilder().build();
} catch (Exception e) {
System.out.println("SessionFactory creation failed");
if (registry != null) {
StandardServiceRegistryBuilder.destroy(registry);
}
}
}
return sessionFactory;
}
public static void shutdown() {
if (registry != null) {
StandardServiceRegistryBuilder.destroy(registry);
}
}
} Это сущность:
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

import com.vividsolutions.jts.geom.Geometry;
import com.vividsolutions.jts.geom.Point;
@Entity
@Table(name = "Points")
public class Points implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE)
private Long id;
private String userId;
private String pointName;
@Type(type = "org.hibernate.spatial.GeometryType")
private Geometry point;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getPointName() {
return pointName;
}
public void setPointName(String pointName) {
this.pointName = pointName;
}
public Geometry getPoint() {
return point;
}
public void setPoint(Geometry point) {
this.point = point;
}
}

В DAO происходит сбой по методу startOperation-> session = HibernateUtil.getSessionFactory (). OpenSession (), но я не понимаю, почему.
