這是我的類代碼：

package database; 

import java.sql.*; 

public class Sqlserver_connection { 
    public static void main(String[] args) { 

     // Create a variable for the connection string. 
     String connectionUrl =  "jdbc:sqlserver://192.168.175.174:1433;DatabaseName=apache_camel;user=User3;password=user3"; 
     //String Connectionurl="jdbc:sqlserver://localhost:1433;DatabaseName=YourDBName;user=UserName;Password=YourPassword" 
     //"databaseName=HelloWorld;integratedSecurity=true;"; 

     // 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); 
        System.out.println(con); 
        // Create and execute an SQL statement that returns some data. 
        String SQL = "SELECT TOP 1000 [username],[password] FROM [apache_camel].[dbo].[login]"; 
        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(1) + " " + rs.getString(1)); 
        } 
      } 

     // 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) {} 
     } 
    } 
}

好，不知道你是否「必須」使用SQLServer的驅動程序，這裏是另一個可用於連接的驅動程序（它在純Java應用程序和Android應用程序上爲我工作），http://jtds.sourceforge.net/非常易於使用，您可以通過類DriverManager提供用戶憑據 t他的靜態方法getConnection（String url，String username，String password），例如：

Connection conn = DriverManager.getConnection（「jdbc：jtds：sqlserver：//192.168.3.67：1433/androiddb」，「sa」 ，「1234」）;

這裏是我幾個星期前發佈的貼子，我回答自己，它具體說明如何設置與jtds的連接，是的，它是爲android，但你可以跳過特定的android步驟（它適用於MS SQL 2008年，我測試了純Java程序）。
