【中文标题】嵌入式 h2 数据库未运行【英文标题】：embedded h2 database not running 【发布时间】：2017-01-16 04:24:42 【问题描述】：我对使用 Spring 处理空间数据非常陌生，我正在尝试开发一个示例，该示例将 Spring 的嵌入式 H2 数据库与空间数据一起使用。 我有我的实体类，并试图提出一个集成类来测试我的服务功能。 不幸的是，我不断收到我不理解的错误消息。协助将不胜感激
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);
和其他类热点
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;

@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。

【问题讨论】：
您使用的是哪个版本的 h2db？ 早期版本有问题github.com/h2database/h2database/issues/85等... 【参考方案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Hotspot 类中location 字段的声明修改为@Column(columnDefinition = "GEOMETRY")，您的表应该可以正常创建。
另外值得注意的是，H2 does not have in-built support 用于空间数据类型。如链接文档中所述，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。
【讨论】：
我正在使用 h2/geodb 并且从这个例子看来运行良好 github.com/mstahv/spring-boot-spatial-example/blob/master/src/… 请将您问题中的列定义 (@Column(columnDefinition=...)) 与我的答案中的列定义以及您链接到的示例进行比较。你会看到为什么你的代码不工作。
啊，我的错。感谢您的帮助【参考方案2】：
我认为问题出在以下字段：
@Column(columnDefinition = "geometry(Point, 4326)")
private Point location;
H2 是否了解 Point 应该映射哪种数据类型？
http://www.h2database.com/html/datatypes.html
我尝试删除上述字段并且它有效。
