In this example we will be creating a simple maven java project to connect to the local mysql instance, without actually installing any jdbc connector and setting it to classpath (maven will take care of this :))
1. Add MySQL connector maven dependency in the pom.xml
2. Sample java source file: Connecting to local mysql instance and listing tables;
