简而言之，我使用User＆lt; - ＆gt; Role＆lt; - ＆gt;数据库中的正确模型，并通过以下代码获取UserDetails上用户的权限：
for (Role role : getRoles()) {
for (Right right : role.getRights()) {
Authority authority = new Authority( controller, action );
authorites.add( authority );
}
}
当我尝试更新由于登录用户而已加载的权限之一（由提到的代码提取）时，它会引发 IllegalStateException ，并将“分配给不同的实体消息“
更新由roo managed merge spect
完成@Transactional
public Right Right.merge() {
if (this.entityManager == null) this.entityManager = entityManager();
Right merged = this.entityManager.merge(this);
this.entityManager.flush();
return merged;
}
org.hibernate.event.internal.EventCache 的 put 方法引发了这个：
if ( oldCopy == null ) {
if ( oldEntity != null ) {
throw new IllegalStateException(
"Error occurred while storing entity " + printEntity( entity ) + ". An entity copy " + printEntity( copy )
+ " was already assigned to a different entity " + printEntity( oldEntity ) + "."
);
}
if ( oldOperatedOn != null ) {
throw new IllegalStateException(
"EventCache#entityToOperatedOnFlagMap contains an entity " + printEntity( entity )
+ ", but EventCache#entityToCopyMap does not."
);
}
}
roo可以被指示生成一般的相等和散列，但我实现了 Right＆amp;的相等和散列。角色类，但没有任何改变。
