無法使用sqljdbc4.jar連接到MSSQL Server 2012

Question

我無法使用sqljdbc4.jar從我的Java應用程序連接到MSSQL Server 2012。

以下是我的代碼：

public static void main(String[] args) { 
    String connectionUrl = "jdbc:sqlserver://172.16.0.4:1433;" + 
      "databaseName=PUC;user=admin;password=admin;instanceName=mssqlserver2012"; 

    // Declare the JDBC objects. 
    Connection con = null; 
    Statement stmt = null; 
    ResultSet rs = null; 

    try { 
     // Establish the connection. 
     Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
     con = DriverManager.getConnection(connectionUrl); 

     // Create and execute an SQL statement that returns some data. 
     String SQL = "SELECT TOP 10 * FROM Patron"; 
     stmt = con.createStatement(); 
     rs = stmt.executeQuery(SQL); 

     // Iterate through the data in the result set and display it. 
     while (rs.next()) { 
      System.out.println(rs.getString(4) + " " + rs.getString(6)); 
     } 
    } 

    // Handle any errors that may have occurred. 
    catch (Exception e) { 
     e.printStackTrace(); 
    } 
    finally { 
     if (rs != null) try { rs.close(); } catch(Exception e) {} 
     if (stmt != null) try { stmt.close(); } catch(Exception e) {} 
     if (con != null) try { con.close(); } catch(Exception e) {} 
    } 
} 

以下是錯誤：

    at java.sql.DriverManager.getConnection(DriverManager.java:579) 
    at java.sql.DriverManager.getConnection(DriverManager.java:243) 
    at Main.main(Main.java:18) 

注：用戶名&密碼是正確的，我已經交叉檢查他們。我的JDK版本是1.7更新21 當我使用JTDS1.3.1駕駛員通過改變連接字符串和驅動程序類，如下所示：

String connectionUrl = "jdbc:jtds:sqlserver://172.16.0.4:1433/PUC;instance=mssqlserver2012;user=admin;password=admin"; 

Class.forName("net.sourceforge.jtds.jdbc.Driver"); 

它的工作原理，但爲什麼不使用Microsoft JDBC驅動程序4.0 SQL服務器？

登錄SQLServerException只是意味着您的用戶名或密碼爲您的MSSQL服務器是錯誤的。我會仔細檢查它們，並記住帽子！
