在春季启动应用程序中连接到Azure MS SQL Server

Question

I'm trying to connect to the azure ms sqlserver database. I have setup these properties in the application.properties file, but I get exceptions, connection timed out.

spring.datasource.url=jdbc:jtds:sqlserver://xxxserver.database.windows.net:port;DatabaseName=xxxdb;user=xxxadmin@xxxserver;password=passwd;encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30;
spring.datasource.username=xxxadmin@xxxserver
spring.datasource.password=passwd
spring.datasource.driver-class-name=net.sourceforge.jtds.jdbc.Driver

spring.jpa.hibernate.ddl-auto=update

I get this exception:

2016-02-16 23:36:46.645 ERROR 7840 --- [           main] o.a.tomcat.jdbc.pool.ConnectionPool      : Unable to create initial connections of pool.

In the past the jtds driver had problems with azure sql due to the driver having problems negotiating the SSL encryption handshake. The recommended driver is the Microsoft one.
