1. org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Network error IOException: Connection refused: connect)
2. Caused by: java.sql.SQLException: Network error IOException: Connection refused: connect
3. Caused by: java.net.ConnectException: Connection refused: connect
这种情况是数据库未开情况下运行tomcat出现的问题，把数据库打开就行了
