Question

我正在尝试通过以下java代码连接到Ms Sql server 2012。

`public class MsSqlServerConnection {

public static void main(String[] args) throws Exception{

    try {

        Driver d = (Driver)Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
    /*  String connectionURL = "jdbc:sqlserver://localhost:1433;databaseName=Gpstrack;user=;password="; */
        Connection connection = null;
        /*Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");*/
        connection = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;user=BARCELONA\\V&V;database=Gpstrack");

        if(connection!=null){
            System.out.println("connection is successfull");
        }else
        {
            System.out.println("Connection error");
        }

    } catch (SQLException e) {
        throw e;
    } catch (Exception e) {
        throw e;
    }

}

}`

当我运行上面的代码时，我收到以下错误。

Exception in thread "main" com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user 'BARCELONA\V&V'.

所以请帮我摆脱这个错误。

您的活动目录域用户密码为空？这是相当不寻常的，有点危险，但我只是试着关注你的问题。

＆＃39; BARCELONA \＆＃39;到sql server表示域名，我没有看到你的连接字符串表示集成安全性。

因此，它可以像在连接字符串中指示集成安全性一样简单：jdbc:sqlserver://localhost:1433;integratedSecurity=true;

请参阅this link for documentation on building your connection string url for jdbc。
