When connecting to a MySQL database, you may encounter this scary warning message.
Thu Feb 04 14:49:25 IST 2016 WARN: Establishing SSL connection without server’s identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn’t set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to ‘false’. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
Your app will continue to work fine … it is just the MySQL database yelling at you.
To get rid of the warning message. Append ?useSSL=false to the end of your database connection string.
Replace – jdbc:mysql://localhost:3306/demo
With – jdbc:mysql://localhost:3306/demo?useSSL=false
Note that I appended ?useSSL=false to the end.
That will get rid of the pesky message … whew!
