your Connection is java.sql.Connection it? I think you quoted the wrong object is not so strong you just want to turn ah

you import a database package may be wrong (import com.mysql.jdbc.Connection ;). I use mysql database, import the package is ( import java.sql.Connection; )

import com.mysql.jdbc.Connection; indeed imported wrong, thank you
