到主机服务器的连接失败。 Java

Question

我在尝试运行查询，但不断收到此错误：

与主机服务器= localhost，命名实例sqlexpress的连接失败。错误：“java.net.UnknownHostException：server = localhost”。验证服务器和实例名称，并检查是否没有防火墙将UDP通信阻止到端口1434.对于SQL Server 2005或更高版本，请验证SQL Server Browser Service是否正在主机上运行。

任何想法？这是我的代码。

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

每答案为Connecting to SQL Server 2008 from Java通过Venkatesh：

Try following connection,

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

Answer 2

有一个在http://msdn.microsoft.com/en-us/library/ms378428%28v=sql.90%29.aspx

在此基础上一个有趣的网站，我想连接的URL应该是：

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