如何使 spring 启动、空间休眠和 postgis 工作？

Question

我无法在创建模式下使用 hibernate-spatial 启动我的 spring boot(2.6.3) 项目。它告诉我类型“几何不存在”。几何类型来自休眠空间库。

然而，我应用了所有必要的东西：

添加hibernate-spatial依赖（我的版本是5.6.3.Final）
使用org.hibernate.spatial.dialect.postgis.PostgisDialect方言而且这个class已经弃用了，同版本对应的文档，还是提示可以用，我什么都不懂(https://docs.jboss.org/hibernate/orm/5.6/userguide /html_single/Hibernate_User_Guide.html#spatial)
使用 geolatte 组或 jts 组的几何类型尽管我有一个错误，它无法创建 table 因为类型“几何不存在”。

这是我的 Maven 依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-spatial</artifactId>
        <version>5.6.3.Final</version>
    </dependency>
    <dependency>
        <groupId>org.postgresql</groupId>
        <artifactId>postgresql</artifactId>
        <version>42.3.1</version>
    </dependency>
    <!--<dependency>

        <artifactId>jts-core</artifactId>

    </dependency>-->


    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

我的属性：

spring:
  datasource:
    driver-class-name: org.postgresql.Driver
    url: jdbc:postgresql://localhost:5432/postgres?currentSchema=hibernatespatial
    username: postgres
    password: 
  jpa:
    hibernate:
      ddl-auto: create
    show-sql: true
    properties:
      hibernate:
        dialect: org.hibernate.spatial.dialect.postgis.PostgisDialect
    open-in-view: false
    database-platform: org.hibernate.spatial.dialect.postgis.PostgisDialect

我的实体class：

package org.test.hibernate.spatial;


import org.geolatte.geom.Geometry;

import javax.persistence.*;

@Entity
@Table
public class Person {

    @Id
    @GeneratedValue
    private Long id;

    private String name;

    private String lastname;

    private String age;

    private Geometry geom;

    public Geometry getGeom() {
        return geom;
    }

    public void setGeom(Geometry geom) {
        this.geom = geom;
    }

    public String getName() {
        return name;
    }

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

    public String getLastname() {
        return lastname;
    }

    public void setLastname(String lastname) {
        this.lastname = lastname;
    }

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }

    public Long getId() {
        return id;
    }

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

我的存储库 class :

package org.test.hibernate.spatial;

import org.springframework.data.jpa.repository.JpaRepository;

public interface PersonRepository extends JpaRepository<Person, Long> {


}

我的靴子class:

package org.test.hibernate.spatial;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@SpringBootApplication
@EnableJpaRepositories
@EnableTransactionManagement
public class TestHibernateSpatialApplication  implements CommandLineRunner {

    public static void main(String[] args) {
        SpringApplication.run(TestHibernateSpatialApplication.class, args);
    }


    public void run(String... args) throws Exception {

    }
}

我的postgreSQL数据库是14版本。有人知道出了什么问题吗？

PostGIS 是 Postgres 扩展，needs to be enabled for each database:

Once PostGIS is installed, it needs to be enabled (Section 3.3, “Creating spatial databases”) or upgraded (Section 3.4, “Upgrading spatial databases”) in each individual database you want to use it in.
[...]
Run the following SQL snippet in the database you want to enable spatially:

CREATE EXTENSION IF NOT EXISTS plpgsql;  
CREATE EXTENSION postgis;

另请注意，扩展默认安装到默认架构（例如 public）。所以 . To prevent this, one could either add the postgis schema to the currentSchema (e.g. jdbc:postgresql://localhost:5432/tst?currentSchema=app1,public), or move postgis to the preferred schema.
