??? 環境
??? 報錯情況
??? 原因分析
??? 解決辦法

環境

??? Java 8
??? Tomcat 8.5

報錯情況

??? 拋出 IllegalArgumentException

??? 具體信息如下：

??? java.lang.IllegalArgumentException: An invalid domain [.jjzm.com] was specified for this cookie
??????? 1

原因分析

??? Tomcat 默認的 CookieProcessor 不支持這種格式的域名。（博主用的 Tomcat 是 Tomcat 8.5）
??? 更具體的信息，請看著介紹 CookieProcessor 的 官方文檔

解決辦法

??? 在 Tomcat 的配置文件 context.xml 的 <Context> 中添加：

???? <CookieProcessor className="org.apache.tomcat.util.http.LegacyCookieProcessor" />

添加后，context.xml(Tomcat版本: 9.0.17)中完整內容為:
