Question

下面是我的存储库，它扩展了spring数据jpa的JpaRepository

 public interface GamesDetailsRepository extends JpaRepository<Game,Integer>{ }

和实体

@Entity
@Table(name="game")
public class Game implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="id")
    private Integer id;

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

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

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

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

    @Column(name="is_portrait")
    private  Boolean portrait;

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

    @Column(name="created_at",insertable = false, updatable = false)
    private  Timestamp createdAt;

    @Column(name="modified_at",insertable = false, updatable = false)
    private  Timestamp modifiedAt;

    @Column(name="is_active")
    private  Boolean active;

    @Column(name="is_active_inflight")
    private  Boolean activeInflight;

    @Column(name="is_blacklisted")
    private Boolean blacklisted;

    @Column(name="provider_id")
    private  Integer providerId;

    @Column(name="position")
    private Integer position;

    /*@OneToOne(mappedBy="id")
    @Column(name="provider_id")
    private Provider provider;*/

    @ManyToMany(cascade = CascadeType.ALL)
    @JoinTable(name="game_tag", joinColumns = @JoinColumn(name = "game_id", referencedColumnName = "id"), inverseJoinColumns = @JoinColumn(name = "tag_id", referencedColumnName = "id"))
    private Set<Tag> tags;

    @ManyToMany(cascade = CascadeType.ALL)
    @JoinTable(name="game_category", joinColumns = @JoinColumn(name = "game_id", referencedColumnName = "id"), inverseJoinColumns = @JoinColumn(name = "category_id", referencedColumnName = "id"))
    private Set<Category> categories;


    /*public Provider getProvider() {
        return provider;
    }

    public void setProvider(Provider provider) {
        this.provider = provider;
    }*/

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

但是当我在做的时候

Game game=gamesDetailsRepository.findOne(id);

结果数据未映射到我的实体，而我能够获取name，image_url等数据，但不能获取描述和provider_id等数据

这是我的mysql表格相同的

为什么只有一些列数据被映射到我的实体，而其他列数据则没有。我已经检查了mysql表，数据存在于coloumn.Any建议？

Spring数据jpa仅映射映射到实体
