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);  
           prepsInsertProduct.execute();  

            // Retrieve the generated key from the insert.  
            resultSet = prepsInsertProduct.getGeneratedKeys();  

            // Print the ID of the inserted row.  
            while (resultSet.next()) { System.out.println("Generated: " + resultSet.getString(1));  
            }  

        }  
        catch (Exception e) {  
            e.printStackTrace();  
        }  
        finally {  
            if (connection != null) try { connection.close(); } catch(Exception e) {}
         // Close the connections after the data has been handled.  
            if (prepsInsertProduct != null) try { prepsInsertProduct.close(); } catch(Exception e) {}

        }  
        }

}

根据您的代码，问题是由 Azure SQL 数据库的连接字符串不正确引起的。

SQL Azure 连接字符串的正确格式如下。

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 旧门户上 DASHBOARD 选项卡右侧栏的链接 Show connection strings 中找到它，或者在 Azure 新门户上的显示数据库连接字符串链接中查看它。

可以参考我对SO线程How to connect to Azure SQL with JDBC的回答看图和代码，或者看官方文章https://azure.microsoft.com/en-us/documentation/articles/sql-database-develop-java-simple/。
