Answer 1

使用的是同一个tomcat的不同端口来访问》？
啥意思，一个tomcat只能存在一个访问端口的，如何个不同端口

Answer 2

而且你这里
Cannot create JDBC driver of class '' for connect URL 'null' 
明显是工程没有找到数据库驱动的错误

Answer 3

url为空了看看连接数据库参数

Answer 4

org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null' 
看看你的url是不是有错端口只能有一个

Answer 5

想看一下你的hibernate配置文件
