Eu quero manter alguns dados no banco de dados H2, criando um repositório CRUD, usando o Hibernate.

Não consigo fazer com que o banco de dados armazene minhas entradas. Atualmente, estou tentando conseguir isso durante a atualização do banco de dados, fazendo uma entrada de exemplo. A entrada está com boa aparência nos logs, mas a tabela não é criada / atualizada / gerada.

Por que o Hibernate não pode criar uma tabela neste caso? (se o problema estiver na estrutura dos meus dados)

Aqui está minha entidade,Game.java classe (tentei sem as anotações @Column, não há diferença. O ID não é gerado automaticamente, preciso poder inserir meu próprio ID toda vez):

@Entity
@Table(name = "GAME")
public class Game {

    @Id
    @Column (name = "ID")
    private long id;

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

    @Column(name = "STORYLINE", length = 4000)
    private String storyline;

    @Column(name = "AGGREGATED_RATING")
    @JsonProperty("aggregated_rating")
    private double aggregatedRating;

    @Column(name = "FIRST_RELEASE_DATE")
    @JsonProperty("first_release_date")
    private long firstReleaseDate;

    @Embedded
    private Cover cover;

    public Game(){

    }

    public Game(long id, String name, String storyline, double aggregatedRating, long firstReleaseDate, Cover cover) {
        this.id = id;
        this.name = name;
        this.storyline = storyline;
        this.aggregatedRating = aggregatedRating;
        this.firstReleaseDate = firstReleaseDate;
        this.cover = cover;
    }

    public long getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getStoryline() {
        return storyline;
    }

    public double getAggregatedRating() {
        return aggregatedRating;
    }

    public long getFirstReleaseDate() {
        return firstReleaseDate;
    }

    public Cover getCover() {
        return cover;
    }


}

E aqui estáCover.java classe:

@Embeddable
public class Cover {

    @Column (name = "URL")
    private String url;
    @JsonProperty("cloudinary_id")
    @Column (name = "CLOUDINARY_ID")
    private String cloudinaryId;
    @Column (name = "WIDTH")
    private Integer width;
    @Column (name = "HEIGHT")
    private Integer height;

    public Cover(){
    }

    public Cover(String url, String cloudinaryId, Integer width, Integer height) {
        this.url = url;
        this.cloudinaryId = cloudinaryId;
        this.width = width;
        this.height = height;
}

    public String getUrl() {
        return url;
    }

    public String getCloudinaryId() {
        return cloudinaryId;
    }

    public Integer getWidth() {
        return width;
    }

    public Integer getHeight() {
        return height;
    }

}

Eu configurei o banco de dados H2 aqui, emapplication.properties Arquivo:

spring.h2.console.enabled=true
spring.h2.console.path=/h2_console
spring.datasource.url=jdbc:h2:mem:test;DB_CLOSE_DELAY=-1
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driverClassName=org.h2.Driver
spring.jpa.hibernate.ddl-auto = update
spring.jpa.show-sql=true
logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql.BasicBinder=TRACE

Repositório está configurado assim:

import org.springframework.data.repository.CrudRepository;

import java.util.List;

public interface GameRepository extends CrudRepository<Game, Long> {
    List<Game> findAllByName(String name);
}

Eu testo meu repositório acessando localhost: 8080 / test, onde uma entrada de amostra deve ser inserida na tabela:

@RequestMapping("/test")
public String saveSth(){
    gameRepository.save(new Game(127, "Assassin's Creed II", "The lineage continues as this new chapter introduces Ezio, inheritor of the talents and creed of the Assassins. His family murdered by rival families, Ezio resolves to learn the ancient art of the Assassin in order to seek revenge. He will not do so alone though, allying with historical figures such as philosopher and writer Niccolò Machiavelli. You will also be able to master the art of the assassin with all new weapons and instruments created by the renowned inventor and genius of the Renaissance, Leonardo Da Vinci himself.", 90.25, 1258416000000L, new Cover("//images.igdb.com/igdb/image/upload/t_thumb/doczeiofd1ckpapdhqs7.jpg", "doczeiofd1ckpapdhqs7", 1000, 1426)));
    return "success";
}

Eu recebo o seguinte log:

Parece que os dados estão vinculados aos parâmetros, mas no console H2SELECIONE * DO JOGO retorna-me: SELECT * FROM GAME; Tabela "JOGO" não encontrada; Instrução SQL: SELECT * FROM GAME [42102-193] 42S02 / 42102 (Ajuda)

Eu tentei outros modos H2, como criar ou soltar, mas sem sucesso. O que me preocupa é que nem consigo que o banco de dados crie uma tabela vazia com as linhas corretas, prontas para as entradas.

Acho que algo está errado com minha Entidade ou está ausente na configuração do GameRepository, mas não tenho mais ideias para corrigir esse erro.

Eu quero alcançar o que está aqui:http://javasampleapproach.com/spring-framework/spring-boot/integrate-h2-database-springboot-spring-jpa-embedded-mode E aqui:http://www.simplecodestuffs.com/value-object-entity-object-in-hibernate-mapping/

Além disso, tentei este conjunto de tutoriais para variar:https://springframework.guru/using-the-h2-database-console-in-spring-boot-with-spring-security/ https://springframework.guru/spring-boot-web-application-part-3-spring-data-jpa/

Mas sem sorte até agora.
