在linux服务器下使用rz上传压缩文件，用unzip命令解压zip包
#xxx.zip 压缩的包名 unzip xxx.zip Archive: QY.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of QY.zip or QY.zip.zip, and cannot find xxx.zip.ZIP, period.
报这种错误说明在文件上传或下载的过程中出现了文件丢失的情况，需要使用sftp或scp重新上传文件到服务器，然后使用unzip命令或jar命令解压压缩文件
#方法一 unzip xxx.zip #方法二 jar -xvf xxx.zip
