How to map the same column two times in other entity

i'm new using hibernate to map entities, i'm trying to use the same column in two different variables for one of my entities, let me explain it, i have an entity called "Matches", this entity will contain information regarding a match, including the localTeam and the awayTeam.

The other entity is Team, one match has two different Teams and Team can have several matches with other Teams.

When i'm try to retrieving all the matches i'm getting an Exception

I'm using SpringBoot 2.1.7, Java 8 and Hibernate 5


@Entity(name = "matches")
public class Matches {

    //Attributes
    @Id
    @Column(name = "id", unique = true, nullable = false)
    private Long id;

    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "local_team_id", referencedColumnName = "id")
    private Team localTeam;

    @OneToOne(cascade = CascadeType.ALL)
    @JoinColumn(name = "away_team_id", referencedColumnName = "id")
    private Team awayTeam;


@Entity(name = "teams")
public class Team {

    //Attributes
    @Id
    @Column(name = "id", unique = true, updatable = false, nullable = false)
    private Long id;


    @OneToOne(mappedBy = "localTeam")
    private Matches localMatches;

    @OneToOne(mappedBy = "awayTeam")
    private Matches awayMatches;

When i try to get all the matches loaded , i got this, i can figure is about how i declared the association between Matches an Team, but i'm still confused about how should i declare it.

I think you have a @oneToMany connection in with local/awayTeam -> matches because a team can also play in serveral matches.

|Team A | matches | team B |

| 1 | a | 2 |

| 1 | b | 3 |

| 1 | c | 4 |

| 1 | d | 5 |

and so one

@OneToMany(mappedBy = "localTeam")
private Iterable<Matches> localMatches;

@OneToMany(mappedBy = "awayTeam")
private Iterable<Matches> awayMatches;

For a team there can be many away and local matches. SO you have to keep a List or set there in Team for fetching matches, as shown below:

Matches

    @Entity(name = "matches")
        public class Matches {

            //Attributes
            @Id
            @Column(name = "id", unique = true, nullable = false)
            private Long id;

            @OneToOne(cascade = CascadeType.ALL)
            @JoinColumn(name = "local_team_id", referencedColumnName = "id")
            private Team localTeam;

            @OneToOne(cascade = CascadeType.ALL)
            @JoinColumn(name = "away_team_id", referencedColumnName = "id")
            private Team awayTeam;
}

Team Entity 

 @Entity(name = "teams")
    public class Team {

        //Attributes
        @Id
        @Column(name = "id", unique = true, updatable = false, nullable = false)
        private Long id;


        @OneToOne(mappedBy = "localTeam")
        private Set<Matches> localMatches=new HashSet<Matches>();

        @OneToOne(mappedBy = "awayTeam")
        private Set<Matches> awayMatches=new HashSet<Matches>();

}

Can you try this, 

@Entity(name = "matches")
    public class Matches {

        //Attributes
        @Id
        @Column(name = "id", unique = true, nullable = false)
        private Long id;

        @OneToOne(cascade = CascadeType.ALL)
        @JoinColumn(name = "local_team_id", referencedColumnName = "id")
        private Team localTeam;

        @OneToOne(cascade = CascadeType.ALL)
        @JoinColumn(name = "away_team_id", referencedColumnName = "id")
        private Team awayTeam;


    @Entity(name = "teams")
    public class Team {

        //Attributes
        @Id
        @Column(name = "id", unique = true, updatable = false, nullable = false)
        private Long id;


        @OneToOne(mappedBy = "localTeam")
        private Set<Matches> localMatches;

        @OneToOne(mappedBy = "awayTeam")
        private Set<Matches> awayMatches;
