具有两个多对一关系的实体关系

Question

I need to implement user invitations and i have a little problem with mapping entities. I have User entity which have set of invitations and a invitation have User field and inviting User field. In this way I have two User fields that are the same.

User side:

@OneToMany(mappedBy="user")
public Set<Invitation> invitations;

Invitation:

@ManyToOne
@JoinColumn(name="idInvitingUser", insertable=false, updatable=false)
public User invitingUser;

@ManyToOne
@JoinColumn(name="idUser")
public User user;

How can I map this proper ?

Answer 1

I guess you will need two sets of invitations on the user side: invitations sent and invitations received.

UPDATE:

@OneToMany(mappedBy="user")
public Set<Invitation> invitations;

@OneToMany(mappedBy="invitingUser")
public Set<Invitation> invitationsSent;
