tomcat 8.5 及其 9.0 response写cookie 设置damain为 [.test.com] 出错 An invalid domain [.test.com] was specified for this cookie

抛出异常:

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

参考博客:

解决方法

1、设置为一级域名 test.com 前面不加 .

2、tomcat的CookieProcessor降级 使用LegacyCookieProcessor 而非Rfc6265CookieProcessor

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