Answer 1

Caused by: java.sql.SQLException: Io 异常: The Network Adapter could not establish the connection 
你的网络适配器\网卡出问题了？

Answer 2

没问题，不过装完数据库后吧IP地址改了。不过在MSSQLSERVER协议中也吧IP地址改了

Answer 3

ERROR: org.hibernate.util.JDBCExceptionReporter#logExceptions : Cannot create PoolableConnectionFactory

Answer 4
