嵌入式H2数据库未运行

Question

I am pretty new to using spring with spatial data and I am trying to develop an example that makes use of spring's embedded H2 database with and the spatial data. I have my entity classes and am trying to come up with an integration class to test my service functions. Unfortunately, I keep getting this error message that I do not understand. Assistance would be appreciated

package com.whot.domain;

import javax.persistence.*;
import java.io.Serializable;

@Entity
public class Address implements WhotEntity{

    @Id
    @SequenceGenerator(name="addressIdSeq", sequenceName = "address_id_seq")
    @GeneratedValue(strategy= GenerationType.AUTO, generator = "addressIdSeq")
    private Long id;
    @Column(name="street_name")
    private String streetName;
    private Long unit;
    @Column(name = "street_number")
    private Long number;

    public Address(String streetName, Long unit, Long number) {
        this.streetName = streetName;
        this.unit = unit;
        this.number = number;
    }

    public Address(String streetName, Long number){
        this(streetName, -1L, number);
    }

    public Address(){

    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getStreetName() {
        return streetName;
    }

    public void setStreetName(String streetName) {
        this.streetName = streetName;
    }

    public Long getUnit() {
        return unit;
    }

    public void setUnit(Long unit) {
        this.unit = unit;
    }

    public Long getNumber() {
        return number;
    }

    public void setNumber(Long number) {
        this.number = number;
    }

    public String toString(){
        return String.format("%s[id: %d]", getClass().getName(), id);
    }
}

and the other class Hotspot

package com.whot.domain;

import org.springframework.data.geo.Point;

import javax.persistence.*;

@Entity
public class Hotspot implements  WhotEntity{

    @Id
    @SequenceGenerator(name="hotspotIdSeq", sequenceName = "hotspot_id_seq")
    @GeneratedValue(strategy= GenerationType.AUTO, generator = "hotspotIdSeq")
    private Long id;
    private String name;
    @OneToOne
    @JoinColumn(name = "ADDR_ID")
    private Address address;
    @Column(columnDefinition = "geometry(Point, 4326)")
    private Point location;

    public Hotspot(String name, Address address, Point location) {
        this.name = name;
        this.address = address;
        this.location  = location;
    }

    public Hotspot() {
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Address getAddress() {
        return address;
    }

    public void setAddress(Address address) {
        this.address = address;
    }

    public Point getLocation() {
        return location;
    }

    public void setLocation(Point location) {
        this.location = location;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof Hotspot)) return false;

        Hotspot hotspot = (Hotspot) o;

        if (getId() != null ? !getId().equals(hotspot.getId()) : hotspot.getId() != null) return false;
        if (getName() != null ? !getName().equals(hotspot.getName()) : hotspot.getName() != null) return false;
        if (getAddress() != null ? !getAddress().equals(hotspot.getAddress()) : hotspot.getAddress() != null)
            return false;
        return getLocation() != null ? getLocation().equals(hotspot.getLocation()) : hotspot.getLocation() == null;
    }

    @Override
    public int hashCode() {
        int result = getId() != null ? getId().hashCode() : 0;
        result = 31 * result + (getName() != null ? getName().hashCode() : 0);
        result = 31 * result + (getLocation() != null ? getLocation().hashCode() : 0);
        return result;
    }

    public String toString(){
        return String.format("%s[id: %d]", getClass().getName(), id);
    }
}

I have my integration test class which I am trying to setup and I have this

package com.whot.dao;

import com.whot.domain.Address;
import com.whot.domain.Hotspot;
import com.whot.repository.AddressRepository;
import com.whot.repository.HotspotRespository;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.orm.jpa.DataJpaTest;
import org.springframework.boot.test.autoconfigure.orm.jpa.TestEntityManager;
import org.springframework.data.geo.Point;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import java.util.HashSet;
import java.util.Iterator;
import java.util.List;

import static org.junit.Assert.assertNotNull;
import static org.junit.Assert.assertTrue;

/**
 * Created by Bart on 2017-01-07.
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ActiveProfiles("test")
@DataJpaTest
@Transactional
public class HotspotRepositoryTest {

    @Autowired
    private HotspotRespository hotspotRepo;

    @Autowired
    private AddressRepository addressRepo;

    @Autowired
    private TestEntityManager em;

    private HashSet<String> hotspotSet;

    @Before
    public void setUp(){
        hotspotSet = new HashSet<>();
        addressRepo.save(new Address("Ossiomo Street", -1L, 2L));
        addressRepo.save(new Address("Wilson Avenue", 103L, 2025L));
        addressRepo.save(new Address("Rue Clark", 303L, 2084L));
        addressRepo.save(new Address("Plateau Close", 20L, 40L));


    }


    @Test
    public void TestFindAllHotspots(){

      // some test code here
    }
}

and this is the stacktrace of the exception I get.

Answer 1

LOCATION GEOMETRY(POINT[*], 4326) is not a valid H2 database column declaration. The correct declaration is LOCATION GEOMETRY . If you modify the declaration for the location field in Hotspot class to @Column(columnDefinition = "GEOMETRY") , your table should get created just fine.

It is also worth noting that H2 does not have in-built support for spatial data types. You will require the JTS topology suite on the application class path to be able to use spatial columns, as described in the linked documentation.

Answer 2

I think problem is with below field :

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

Does H2 understand which data type does Point should be mapped ?

I tried removing the the above field and it worked.
