detail.jsp中关于cookie字符的问题？

Question

点开商品后报错 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 causejava.lang.IllegalArgumentException: An invalid character [44] was present in the Cookie value然后上网查是说cookie内容中不能包含逗号“，”，我就将逗号“，”改成了“#”，但是还是会报错请问怎么解决？

你后面是不是有把string转成数字的地方，后面报的错误是因为数字转换过去的时候出错了，你找下，应该是字符串分割没弄好，导致转换数字的时候报错了
