JpaRespository中的自定义连接查询

Question

在我的项目中，我有两个实体：competition和user。用户应该能够观看（最喜欢的）比赛。

@Entity
public class Competition
{
    @Id
    @GenericGenerator(name = "competition_id", strategy = "de.deepsource.jpa.generator.CompetitionIdGenerator")
    @GeneratedValue(generator = "competition_id")
    private String id;

    ...
}

@Entity
public class User
{
    @Id
    private String email;

    ...
}

我通过competitions访问所有PagingAndSortingRepository：

public interface CompetitionRepository extends PagingAndSortingRepository <Competition, String>, 
JpaSpecificationExecutor <Competition>
{
}

我通过以下方式获取所有分页结果：

wRep.findAll(spec, pageable)

我现在的问题是：我怎样才能意识到这一点＆＃34;观看＆＃34;功能？
