Question

我对使用具有空间数据的spring非常陌生，我正在尝试开发一个使用spring的嵌入式H2数据库和空间数据的示例。我有我的实体类，我正在尝试提出一个集成类来测试我的服务功能。不幸的是，我一直收到这个我不明白的错误信息。将不胜感激，

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);
    }
}

和其他类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);
    }
}

我有我正在尝试设置的集成测试类，我有这个

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
    }
}

这是我得到的异常的堆栈跟踪。

Answer 1

LOCATION GEOMETRY(POINT[*], 4326)不是有效的H2数据库列声明。正确的声明是LOCATION GEOMETRY。如果您将location课程中的Hotspot字段的声明修改为@Column(columnDefinition = "GEOMETRY")，那么您的表格应该可以很好地创建。

值得注意的是H2 does not have in-built support用于空间数据类型。您将需要应用程序类路径上的JTS拓扑套件才能使用空间列，如链接文档中所述。

Answer 2

我认为问题出在以下领域：

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

H2是否了解Point应该映射哪种数据类型？

我尝试删除上面的字段并且有效。

嵌入式h2数据库未运行
