@ManyToOne hibernate映射序列化

我有兩個SQL表：具有多對一關係的用戶和團隊以及具有FK的user_team表。我想用hibernate映射這個關係。在添加這個關係之前，一切都很好。@ManyToOne hibernate映射序列化

我的表：

用戶：

個

userid bigint (PK) 
firstname text 
lastname text 
login text 
pass text 
email text

團隊：

teamid bigint (PK) 
name text 
owner bigint (FK to users) 
description

user_team：

userid bigint (FK to users) 
teamid bigint (FK to teams)

問題必須在某處映射多對多，但我不能找到它。

試試這個。使用此代碼替換您@JoinTable註釋：

@JoinTable(name = "user_team", joinColumns = { 
    @JoinColumn(name = "fk_to_teams_from_user_team", referencedColumnName = "teamid")}, inverseJoinColumns = { 
    @JoinColumn(name = "fk_to_users_from_user_team", referencedColumnName = "userid")})

感謝的答案，但問題仍然存在 – bglow

可能您發佈表的結構？用戶，團隊和user_team –
