java.sql.SQLException:用户'admin'登录失败

Question

免责声明:我之前从未使用过SQL服务器.

我正在尝试使用java代码连接到SQL Server Express.

public class Test1 {

    public static void main(String[] args) throws SQLException, ClassNotFoundException {
        Class.forName("net.sourceforge.jtds.jdbc.Driver");
        String url = "jdbc:jtds:sqlserver://localhost:1433/POC;instance=MOHITCH-LAPTOP/SQLEXPRESS";
        String user = "admin";
        String password = "admin";
        Connection conn = DriverManager.getConnection(url, user, password);
        Statement st = conn.createStatement ();
            ResultSet rs = st.executeQuery("select * from POC.dbo.poc_table");
            while (rs.next())
            {
                System.out.println(rs.getInt(1) + " " + rs.getString(2));
            }
        }
    }

我得到了例外:

Exception in thread "main" java.sql.SQLException: Login failed for user 'admin'.

    at java.sql.DriverManager.getConnection(Unknown Source)
    at my.java.Test1.main(Test1.java:16)

我也尝试使用MS SQL服务器Management Studio 2014登录.我成功地做到了.

这是我的数据库结构:

我认为您需要修改服务器中的某些配置.

请按照以下步骤操作,希望这对您有所帮助.

1. Open your SQL Server Management Studio.

2. Database server right click and go to properties.

3. Choose Security option and check SQL Server and Windows authentication mode.

4. Enable TCP/IP connection in SQL Configuration Manager.

5. Restart your SQL server service.
