Answer 1

according to your code, the issue was caused by the incorrect connection string for Azure SQL Database.

The correct format of connection string for SQL Azure is like below.

jdbc:sqlserver://<hostname>.database.windows.net:1433;database=<database-name>;user=<username>@<hostname>;password={your_password_here};encrypt=true;hostNameInCertificate=*.database.windows.net;loginTimeout=30;

That you can find it at the link Show connection strings of the right bar of the tab DASHBOARD on Azure old portal, or see it at the link Show database connection strings on Azure new portal.

You can refer to my answer for the SO thread How to connect to Azure SQL with JDBC to see the figures and codes, or see the offical article https://azure.microsoft.com/en-us/documentation/articles/sql-database-develop-java-simple/ .
