spring-config.xml

<bean id="dataSource"  
  class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
  <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />  
  <property name="url" value="jdbc:sqlserver://vinayaka.cloudapp.net,555\sqlexpress;database=Sample" />

请注意：

1）我能够打开和SQL Server Management Studio中的服务器上运行。

1) I am able to open and work on that server in SQL Server Management Studio.

2）如果我能够在SQL Server Management Studio打开，这意味着我的机器的IP地址是由防火墙。

2) If I am able to open in SQL Server Management Studio, it means my machine IP address is allowed by firewall.

3）我可以连接到SQL Azure的数据库创建的数据库。

3) I can connect to database created in Azure SQL Database.

请在此给出建议。
