未使用 Spring JPA 从 H2 DB 加载数据

我正在尝试使用 Spring JPA 从 H2 数据库中卸载所有数据，单击 http://localhost:8080/greeting链接 后，输出为空。如何从表中获取所有数据？

控制器：

package RestExample.MainPack.Controller;

import RestExample.MainPack.model.salespointdo;
import RestExample.MainPack.repos.SalesPointRepos;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class GreetingController {

    @Autowired
    SalesPointRepos salesPointRepos;


    @GetMapping("/greeting")
    @ResponseBody
    public String greeting() {


        salespointdo ss= new salespointdo();

        Iterable<salespointdo> allSP=salesPointRepos.findAll();

        StringBuilder sb= new StringBuilder();

        allSP.forEach(sp->sb.append(sp+"<br>"));


        return  allSP.toString();
    }
}

实体：

    package RestExample.MainPack.model;

import javax.persistence.*;

@Entity
@Table(name = "salespointdo")
public class salespointdo {

 @Id
 @GeneratedValue(strategy = GenerationType.AUTO)
 private Long id;

 @Column(name = "name")
 private String name;

 @Column(name = "city")
 private String city;

 @Column(name = "address")
 private String address;

    public salespointdo() {
    }

    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 String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getAddress() {
        return address;
    }

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

    @Override
    public String toString() {
        return "City: "+getCity()+" "+"Address: "+getAddress();
    }
}

存储库：

    package RestExample.MainPack.repos;

import RestExample.MainPack.model.salespointdo;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;


@Repository
public interface SalesPointRepos extends CrudRepository<salespointdo,Long> {



}

弹簧靴：

package RestExample.MainPack;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;



@SpringBootApplication
public class StartRest {

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



    }
}

应用程序属性：

spring.h2.console.enabled=true



spring.datasource.url=jdbc:h2:./SalesPoint
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=user
spring.datasource.password=pass
spring.datasource.platform=h2



spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=none
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.H2Dialect

以上导致SpringBoot和H2表的日志以及执行结果
