java - 当 cookie 包含变音字符时 Tomcat 7 异常

我是一名开发人员，当 Cookie 包含变音字符 (ä,ö,ü) 时，我遇到以下异常，我尝试了很多解决方案和配置，但没有任何结果。

我用的是Tomcat7

有什么办法吗

Answer 1

根据对另一个问题的评论，您需要升级到 tomcat 8.0.15(或更高版本)并启用 RFC 6455 cookie 处理器。此处记录:http://tomcat.apache.org/tomcat-8.0-doc/config/cookie-processor.html

通过以下方式在您的 conf/context.xml 中启用它:

<Context>
  <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor" />
</Context>
