DB Browser 新建连接mysql出现“driver not found”

Question

驱动包jar都导入了，但是怎么都连接不上数据库如题求大神解答

Answer 1

没有注册驱动吧，是不是没写
Class.forname("com.mysq.???.Driver");mysql要注册一下的

Answer 2

没有数据库的 jar ，或者jar放的位置不正确

Answer 3

如果你相信自己的连接没写错误的话,还是换一下jar吧!!!有时候的确有这个毛病!!!

Answer 4

驱动的问题还是没解决，但是经过一番调试网页，什么的都可以打开就是注册信息时出错，用以前的帐号可以登录，PS：这是用hibernate框架构建的我不怎么懂。唉

Answer 7

缺少相关jar，你把你下载的那个工程，在webinf/lib中看看所有的jar是否齐全。需要hibernate的jar，mysql驱动等

Answer 8

应该是少了hibernate的包，你检查一下吧
