org.apache.catalina.startup.HostConfig.deployWAR Error deploying web application archive

本文主要是介绍org.apache.catalina.startup.HostConfig.deployWAR Error deploying web application archive,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

昨天23点给一个老项目改完打包发布到云服务器后报错,Tomcat9 启动不了,白折腾了我几个小时。

这错误以前遇到过,由于太过久远已经忘记,特此记录

过程

我的环境是 CentenOS7 + Tomcat9 + jdk8 + Springboot2.*

报错后我在网上查了很多资料,五花八门的解决办法层出不穷

然并卵,一如既往的废话。

 

网上纷纭

1、有说改 JAVA_HOME 下 jre/lib 下某个和随机数相关的配置 (改了,没用)

2、有说换 Tomcat 大版本的(没试过、麻烦)

3、有说改 Tomcat conf 下 c..  某某配置文件的 (一看就没用)

4、有说 jdk 低了的 (我的是1.8,所以不可能)

5、有说 Spring***框架相关环境版本不一致的(只要在编辑器里能跑一般不存在)

5、一个靠谱点的帖子: Tomcat/conf/server.xml 里面 Host 节点下 Context 节点的 docBase 属性对应的项目错误 (这个有可能,但我的没问题)

 

解决办法

最终! 我看到了一个评论(评论:考虑是否重复打包),突然灵光一闪,想起了以前是怎么解决的。

我一拍大腿!清空了 target 文件夹,再次打包,发布,成功!
