錯誤連接到SQL Server數據庫

Question

當我嘗試用下面的代碼連接到我的數據庫：

try 
{ 
    String connectionUrl = "jdbc:sqlserver://192.168.0.78;instanceName=SQL2014;databaseName=GIDS;user=sa;password=invent"; 
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
    Connection con = DriverManager.getConnection(connectionUrl); 
    System.out.println("Database connection = "+con); 
} 
catch(Exception e) 
{ 
    e.printStackTrace(); 
    System.out.println("Error connecting to database. Error: "+e.getMessage()); 
} 

我得到以下異常：

Error: com.microsoft.sqlserver.jdbc.SQLServerDriver

我在做什麼錯？

Answer 1

嘗試這個代碼

try 
{ 
    String username = "sa"; 
    String password = "invent"; 
    String connectionUrl = "jdbc:sqlserver://192.168.0.78;instanceName=SQL2014;databaseName=GIDS"; 
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
    Connection con = DriverManager.getConnection(connectionUrl,username,password); 
    System.out.println("Database connection = "+con); 
} 
catch(Exception e) 
{ 
    e.printStackTrace(); 
    System.out.println("Error connecting to database. Error: "+e.getMessage()); 
}

確保你有實現類（驅動程序jar）以連接o MS SQL類路徑罐子。
