大神指点

[hp961218]

大兄弟，你好歹说下，这是什么情况下，出错的呀，贴个异常信息，很难，分析，贴下具体的代码吧

[小了白了兔O.O]

其实我觉得，你贴异常信息的时候大致只要把异常名称贴出来就行了，没必要全都贴，例如这个 java.lang.IllegalArgumentException: non null hash key required 然后你的代码报错的地方应该可以贴一下，或者全部代码，最起码应该说一下是在什么情况下用的啊，亲． 看你这样，是用的spring么，那么可以说一下你在写什么类型的项目么?不然也不知道该怎么回答啊，亲

[LidraguoonDong]

已经解决了，确实是我没有说明白，当时比较急，谢了

[beibiyou]

使用是什么原因

[qq_43294957]

你好，我想问下您当时是大致怎么解决的么？

[qq_41546291]

楼主，我也遇到这个异常了，请问一下你是怎么解决的啊，看着头痛

edis缓存数据时报过这个错误，我的错误原因是存是数据是空，存之前加个非空判断就可以了(判断参数的合法性) value不能为null报错是java.lang.IllegalArgumentException: Value must not be null! 错误是这样产生的： 使用damin用户登陆到管理平台，进入平台后 Shift+Ctrl+delete 清理缓存， 然后点击系统退出按钮 .就会出现java.lang.IllegalArgumentException: Value must not be null! 这时候redis中的缓存已经被清除了，所以拿不到当前admin信息。在退出的时候找不到合法的参数
