Java 通过spring security和通过spring social登录Linkedin支持身份验证

我有一个支持通过linkedin和normal signin登录的应用程序。对于normal signin，使用spring security，对于linkedin signin，使用spring social。如果用户使用用户表中的linkedin密码字段注册，则该用户将为空。当该用户尝试通过normal signin进程登录时，会出现Http 500错误，异常详细信息具体如下

如何处理此错误。。。并为用户显示一条错误消息？

看起来您遇到了。请更新到Spring Security的3.1.6.RELEASE或3.2.2.RELEASE版本，看看它是否解决了您的问题
