Liferay无法通过screenname获取用户

我正在为liferay编写自动登录钩子，它尝试通过screenname获取用户。我用下面的代码来获得用户，这主要是OpenSSOAutoLogin变化：Liferay无法通过screenname获取用户

User user = UserLocalServiceUtil.getUserByScreenName(companyId, screenName);

这在大多数情况下，除非它被记录在Liferay的屏幕名是大写的。例如，如果屏幕名称存储的liferay是'TEST'，我无法获得用户。堆栈跟踪显示如下：

com.liferay.portal.NoSuchUserException: No User exists with the key {companyId=1, screenName=test}

跟踪清楚地表明“没有用户存在关键screenName = test”。这里'test'是用小写字母编写的，但getUserByScreenName（）方法是用大写的screenname调用的。

经过一番研究，我发现在liferay UserLocalServiceImpl中执行了小写转换。我想这是导致搜索失败的原因，但我不确定。

任何人都可以证实吗？生命周期屏幕名称是否应始终为小写？

感谢您的咨询。

我认为'companyId'通过是不正确的。 –

在保存新用户时，Liferay总是将屏幕名称转换为小写。正如你所说，该方法在UserLocalServiceImpl.java

protected String getScreenName(String screenName) { 
    return StringUtil.lowerCase(StringUtil.trim(screenName)); 
}

发现所以，如果你在屏幕名称创建/更新用户时通过与大写没关系，Liferay将永远改变它。
