org.apache.tomcat.util.http.parser.Cookie.logInvalidHeader A cookie header was received

在启动项目时遇到logInvalidHeader 的警告，当然不影响系统的运行，

先说问题来源： 是因为新版tomcat的cookie处理warn比老版严格造成，由tomcat6升级到tomcat8就会有这个问题。

[http-nio-8080-exec-5] org.apache.tomcat.util.http.parser.Cookie.logInvalidHeader A cookie header was received [XX] that contained an invalid cookie. That cookie will be ignored.Note: further occurrences of this error will be logged at DEBUG level.
解决方法：添加LegacyCookieProcessor文件来替代默认的cookie设置。（cookie解析器）

cat /usr/local/apache-tomcat-8.5.12/conf/context.xml

WEB-INF/web.xml
${catalina.base}/conf/web.xml

Rfc6265CookieProcessor这个配置不管用，问题出处：

配置方案LegacyCookieProcessor说明：
