點開商品后報錯

?Servlet.service() for servlet [jsp] in context with path [/ServletCartDemo] threw exception [java.lang.IllegalArgumentException: An invalid character [44] was present in the Cookie value] with root cause

java.lang.IllegalArgumentException: An invalid character [44] was present in the Cookie value

然后上網查是說cookie內容中不能包含逗號“，”，

我就將逗號“，”改成了“#”，但是還是會報錯

請問怎么解決？
