使用的示例代码

package UtilityCreateSensorData;
// Use the JDBC driver  
import java.sql.*;  
import com.microsoft.sqlserver.jdbc.*;  

public class SQLDatabaseConnection {

     // Connect to your database.  
    // Replace server name, username, and password with your credentials  
    public  void InsertData(String Value1,String Value2,String Value3,int Value4) {  

        String connectionString ="jdbc:sqlserver://test.database.windows.net:1433;database=test;user=TestUsername;password=TestPassword";  


        // Declare the JDBC objects.  
        Connection connection = null; 
        Statement statement = null;   
        ResultSet resultSet = null;  
        PreparedStatement prepsInsertProduct = null; 


        try {  
            connection = DriverManager.getConnection(connectionString); 
            // Create and execute an INSERT SQL prepared statement.  
           String insertSql = "INSERT INTO [dbo].[tblAutomationTest] (DESC,MessageStart,MessageEnd,SenseCount) VALUES " + "(Value1, Value2, Value3, Value4);";  

           prepsInsertProduct = connection.prepareStatement(insertSql, Statement.RETURN_GENERATED_KEYS);

根据您的代码，问题是由Azure SQL数据库的错误连接字符串引起的。

SQL Azure的正确连接字符串格式如下所示。

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;

您可以在Azure旧门户网站上Show connection strings选项卡右侧栏的链接DASHBOARD找到它，或者在Azure新门户网站上显示数据库连接字符串链接中查看。

您可以参考我对SO帖子How to connect to Azure SQL with JDBC的回答来查看数字和代码，或查看官方文章https://azure.microsoft.com/en-us/documentation/articles/sql-database-develop-java-simple/。

使用JDBC驱动程序
