Question

我正在为liferay编写一个自动挂载钩子，它试图通过screenname获取用户。我正在使用以下代码来获取用户，这主要是OpenSSOAutoLogin的变体：

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

这在大多数情况下都有效，除非在liferay中记录的screenname是大写的。例如，如果存储的liferay的屏幕名是'TEST'，我就无法获得用户。堆栈跟踪显示如下：

com.liferay.portal.NoSuchUserException: No User exists with the key {companyId=1, screenName=test}
    at com.liferay.portal.service.persistence.UserPersistenceImpl.findByC_SN(UserPersistenceImpl.java:2789)

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

经过一些研究，我发现在liferay UserLocalServiceImpl中执行了小写转换。我想这就是让搜索失败的原因，但我不太确定。

任何人都可以确认吗？ liferay屏幕名称是否应该是小写的？

感谢您的建议。

Answer 1

保存新用户后，Liferay始终将屏幕名称转换为小写。如您所述，该方法可在UserLocalServiceImpl.java中找到

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

因此，如果您在创建/更新用户时使用大写字母传递屏幕名称并不重要，Liferay将始终对其进行转换。

Liferay无法通过screenname获取用户
