在日志中查找：无法创建文件[/usr/local/tomcat/webapps/mywebapp/meta-inf/war-tracker]我寻找解决方案，但没有找到，有人遇到过他吗？

Tomcat:apache-tomcat-9.0.13 openjdk版本“1.8.0_171”

Answer 1

问题是Deployment-WAR中的文件“META-INF/WAR-Tracker”：

来自tomcat-docs：

注意：如果Tomcat扩展WAR文件，那么它将向解压缩的目录结构中添加一个文件(/meta-inf/war-tracking)，在Tomcat不运行时，它使用该文件检测WAR文件中的更改。任何这样的更改都将在Tomcat下次启动时触发删除展开的目录和部署更新的WAR文件。

解决方案：

在部署之前从WAR文件中删除文件“META-INF/WAR-Tracker”，您就设置好了。
