无法在Google Cloud中构建Hibernate SessionFactory

Question

我正在使用我在Google Appengine上部署的Spring Boot应用程序，我想连接到Google Cloud SQL。我已成功激活Google Cloud SQL API，创建了一个实例，并在Google Cloud SQL端创建了一个数据库。我也可以成功地将我的应用程序部署到Appengine，但是一旦我尝试填充我的数据库，我就会收到错误：

java.lang.RuntimeException: org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'entityManagerFactory' defined in class path resource 
[org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]:

我的application.properties文件如下：

spring.jpa.database=MYSQL
spring.datasource.url=jdbc:mysql://google/DB_NAME?cloudSqlInstance=PROJECT_ID:REGION:INSTANCE_NAME&socketFactory=com.google.cloud.sql.mysql.SocketFactory
spring.datasource.username=root
spring.datasource.password=password
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

我有一个实体，如下：

package com.example.demo.model;
import lombok.Getter;
import lombok.Setter;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
@Entity
@Gettter
@Setter
public class Medico {

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

protected Medico() {}

public Medico(String nome, String cognome) {
    this.nome = nome;
    this.cognome = cognome;
}

@Override
public String toString() {
    return "Medico{" +
            "id=" + id +
            ", nome='" + nome + '\'' +
            ", cognome='" + cognome + '\'' +
            '}';
}
}

我有以下存储库：

package com.example.demo.repository;
import com.example.demo.model.Medico;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface MedicoRepository extends CrudRepository<Medico, Long> {
    List<Medico> findMedicoByCognome(String cognome);
}

最后，我有以下控制器：

package com.example.demo;
import com.example.demo.model.Medico;
import com.example.demo.repository.MedicoRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class MainController {

@Autowired
MedicoRepository repository;

@GetMapping("/medici")
public String hello() {
    String results = "";
    repository.save(new Medico("Jack", "Bauer"));
    repository.save(new Medico("Chloe", "O'Brian"));
    repository.save(new Medico("Kim", "Bauer"));
    repository.save(new Medico("David", "Palmer"));
    repository.save(new Medico("Michelle", "Dessler"));
    results += "Medici found with findAll():";
    results += "-------------------------------";
    for (Medico medico : repository.findAll()) {
        results += medico.toString();
    }
    return results;
}
}

我不确定出了什么问题。任何建议都非常感谢！
