部署包启动报错吗，部署环境说下

回复第2楼
linux 6.6    mysql5.1  apache-tomcat-8.5.6 jdk1.8
先安装jeecmsv7报错，以为是tomcat8版本高原因，接着升级v7-update-v8，还是报同样的错误。

你是不是项目二次开发过了

回复第4楼
没有开发过，直接用官方帮打包好的

回复第5楼
方便帮QQ远处看一下么

有没有建库，jdbc改了吗

[root@nginxtest config]# cat jdbc.properties 
#mysql\u914d\u7f6e
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/jeecms?characterEncoding=UTF-8
jdbc.username=root
jdbc.password=*****

有建库，JDBC也改了

jdk不是用的openJdk吧

jdk-8u121-linux-x64.tar.gz
