java - JPA : entity object is not appeared in the H2 console

Question

在我的 Spring 应用程序中，我有以下实体:

import lombok.Data;

@Data
@Entity

public class Profile {

    @Id
    @GeneratedValue
    Long id;

    String name;
    String address;
    String description;
    String img;

public Profile(String name, String address, String description, String img) {
        this.name = name;
        this.address = address;
        this.description = description;
        this.img = img;
    }

}

然后存储库是:

@Repository
public interface ProfileRepository extends JpaRepository<Profile,Long> {

}

这是我的pom.xml:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-devtools</artifactId>
    <scope>runtime</scope>
</dependency>
        <dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <scope>runtime</scope>
</dependency>

所以，我希望当我进入 h2 控制台 uri 时:

http://localhost:8080/h2-console/login.do?jsessionid=ae6ba7021a23e0ebb4a4844381546e72

它显示与对象Profile相关的表。

问题是:没有名为 Profile 的表。

那么，为什么我没有个人资料表？

application.properties 为空

这是我如何连接到 H2

当我运行我的应用程序时，它说:

[2m2017-06-29 10:07:21.106[0;39m [32m INFO[0;39m [35m51392[0;39m [2m---[0;39m [2m[  restartedMain][0;39m [36morg.hibernate.dialect.Dialect           [0;39m [2m:[0;39m HHH000400: Using dialect: org.hibernate.dialect.H2Dialect

所以，看起来，应用程序制作了数据库的架构。我说得对吗？

Answer 1

您需要在application.properties中设置h2配置写下这些行

spring.h2.console.enabled=true
spring.datasource.url=jdbc:h2:mem:testdb --> whatever url you find when open console
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=
spring.jpa.hibernate.ddl-auto=create
