Answer 1

当auto-deploy设置为true，并且我通过慢速连接将war文件上传到Linux服务器时，我会看到这个问题。由于某些原因，Tomcat试图在完成上传到服务器之前部署WAR。关闭自动部署并手动执行，或者将文件ftping到服务器上的其他目录而不是webapps，然后将其移动到webapps中可以解决问题。

似乎Tomcat没有等到文件上传完成后再尝试展开它的问题。

Answer 2

如果您是在Linux上部署，那么确保tomcat进程运行时的用户是可读的。对war文件运行"chmod +r“，以向每个人添加读取权限。

Answer 3

您是否以ASCII模式(而不是二进制)将文件从Windows传输到Unix？

这可能是文件损坏的原因之一。你也许可以在windows上用ZIP打开--但是请尝试

在Unix上使用jar tvf <filename>查看内容是否正确。
