到主機服務器的連接失敗。 Java

Question

我在嘗試運行查詢，但不斷收到此錯誤：

與主機服務器= localhost，命名實例sqlexpress的連接失敗。錯誤：「java.net.UnknownHostException：server = localhost」。驗證服務器和實例名稱，並檢查是否沒有防火牆將UDP通信阻止到端口1434.對於SQL Server 2005或更高版本，請驗證SQL Server Browser Service是否正在主機上運行。

任何想法？這是我的代碼。

public static void main(String[] args) { 
     try { 
      try { 
       // TODO code application logic here 
       Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 

      // Connection dbConnection = DriverManager.getConnection("jdbc:jtds:sqlserver://127.0.0.1:1433/myDatabase; instance = SQLEXPRESS","sa","password"); 
      String Connectionurl="jdbc:sqlserver://server=Owner-PC\\SQLEXPRESS; DatabaseName=myDatabase;"; 
      Connection dbConnection = DriverManager.getConnection(Connectionurl,"sa","password"); 
      Statement myStmt = dbConnection.createStatement(); 

       String query = "INSERT INTO People(ID, Name, Surname, Age, Contact, Location, Course) VALUES" 
         + " (1007, 'Elroy', 'Smith', 33, 21366688, 'Somewhere', 'somecourse')"; 

       myStmt.executeUpdate(query); 


       myStmt.executeQuery(query); 

       } catch (ClassNotFoundException ex) { 
       Logger.getLogger(JavaApplication2.class.getName()).log(Level.SEVERE, null, ex); 
      } 
     } catch (SQLException ex) { 
      Logger.getLogger(JavaApplication2.class.getName()).log(Level.SEVERE, null, ex); 
     } 
    } 

Answer 1

每答案爲Connecting to SQL Server 2008 from Java通過Venkatesh：

Try following connection,

String Connectionurl="jdbc:sqlserver://localhost:1433;DatabaseName=myDatabase" 

Answer 2

有一個在http://msdn.microsoft.com/en-us/library/ms378428%28v=sql.90%29.aspx

在此基礎上一個有趣的網站，我想連接的URL應該是：

jdbc:sqlserver://Owner-PC;instanceName=SQLEXPRESS;DatabaseName=myDatabase;
