springboot adminServer2.0+部署踩坑记

本次部署springboot adminServer的版本是2.3.0

一、 前情提要

整个项目的搭建，很简单，不必多说，主要说一下这次部署踩到的一个坑，记录一下，也为可能遇到的提供参考，具体报错信息如下：

 2020-10-26 17:50:44.732 INFO 10 --- [nio-8080-exec-2] o.apache.tomcat.util.http.parser.Cookie : A cookie header was received [1591853885,1591853965] that contained an invalid cookie. That cookie will be ignored.Note: further occurrences of this error will be logged at DEBUG level.

Error has been observed at the following site(s):|_ checkpoint ⇢ Request to GET health [DefaultWebClient]

主要看到报错信息是：reactorty.http.client.PrematureCloseException: Connection prematurely closed BEFORE response

二、解决方案

reactor-netty的版本有问题，直接把reactor-netty的升到0.9.10.RELEASE即可解决。
