@ManyToOne休眠映射序列化

[英]@ManyToOne hibernate mapping serialization

 原文  2013-12-11 19:50:55  7   1    java/ hibernate/ many-to-many

問題描述

我有兩個SQL表：具有多對一關系的用戶和團隊，以及具有FK的user_team表。 我想使用休眠映射此關系。 在添加此關系之前，一切正常。

我的堆棧跟蹤：

我的桌子：

用戶： 

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)

問題一定在ManyToMany映射中，但是我找不到。

嘗試這個。 用以下代碼替換@JoinTable批注： 

@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")})
