Above error is generic error and there are many possibilities 
- Check database username and password are correct, try login to database through some database client and check if it is working.
- Also make sure your connection string is correct. Sometime if some quotes or something is missed in database connection string it may cause issue and you will get below errors. ( try to run diff between old and new file) 
-  lastly if you have taken backup of confluence.cfg.xml file then try to restore this or revert changes and start confluence just to make sure if it is working with old configuration.

Thank for your quick reaction,Taha Khanzada. Maybe i didn't make myself so clear .My database configuration is in the <CONFLUENCE_HOME>/confluence.cfg.xml ,and i have changed the url of mysql,and then it reported errors as above.And i have use the "ping" to test my url,it works well.Is there any more possible solutions to my problems ?

Database details could be in /confluence.cfg.xml or /conf/server.xml Depending upon how your database is configured. You can refer below doc for more info on how to configure database in confluence https://confluence.atlassian.com/doc/configuring-a-mysql-datasource-in-apache-tomcat-1867.html
