尊敬的用户我的问候，我是新手与Spring Boot ，我想只是创建简单的表在H2数据库，这是模型类

@Entity
public class Human 

{

    @Id
    private long id;

    private String firstname;

    private String lastname;

        private String email;

        public long getId() {
            return id;
        }



        public void setId(int id) {
            this.id = id;
        }
        public String getFirstname() {
            return firstname;
        }
        public void setFirstname(String firstname) {
            this.firstname = firstname;
        }
        public String getLastname() {
            return lastname;
        }
        public void setLastname(String lastname) {
            this.lastname = lastname;
        }
        public String getEmail() {
            return email;
        }
        public void setEmail(String email) {
            this.email = email;
        }
}

这是pom.xml：

application.properties：

spring.h2.console.enabled= true
spring.h2.console.path=/h2
spring.datasource.url=jdbc:h2:file:~/user
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driver-class-name=org.h2.Driver

在此之前，应用程序运行良好，唯一的问题是表未显示在H2控制台中（我不知道它是否真的创建了，但当我使用H2控制台时，表立即创建）
所以拜托有什么问题吗？任何帮助都很感激
