使用重复的电子邮件id'；liferay中用户表中的s

我有一个数字屏幕名12345，其中有它的电子邮件地址enteremail@12345.com在liferay的用户表中。当我创建另一个屏幕名时enteremail@12345.comemailAddress字段已被删除enteremail@12345.com同一张桌子。所以当我尝试用screenname登录时enteremail@12345.comliferay正在引发异常。 堆栈跟踪：

我正在使用Liferay 5.2.3版本。如何解决此问题？

在EMAILADDRESS+COMPANYID列的USER_uuu表中有一个唯一的索引。在OpenSSO登录期间，似乎没有创建第二个用户，因为之前存在具有相同电子邮件的用户。

---

最简单的解决方案是更改第一个用户的电子邮件（来自Liferay GUI或数据库），然后再尝试创建第二个用户。

获得了解决方案。已从Liferay中删除索引IX_615E9F7A，并且它正在工作….

感谢您的回复。但是，我如何删除该索引，因为我希望有两个用户具有相同的电子邮件地址但具有不同的屏幕名称？以下是一些技巧，如将索引更改为非唯一索引和检查重复的UserEmailAddressException：这样做会使您失去通过电子邮件进行身份验证的能力。可能还有其他意想不到的问题。
