SQL Server登录失败（正确输入用户和密码）

Question

问题已更新（不再手动加载DriverManager，而是使用getConnection（）方法）：

package guii;

import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class JdbcSQLServerConnection {

public static void main(String[] args) {

    Connection conn = null;
    Statement st=null;
    ResultSet rs=null;

    try {

        String dbURL = "jdbc:sqlserver://ASUS\\YES:1433;integratedSecurity=false";
        String user = "sa";
        String pass = "12345";
        conn = DriverManager.getConnection(dbURL,user,pass);
        String query="SELECT * FROM test";
        st=conn.createStatement();
        rs=st.executeQuery(query);

        while(rs.next()){
            System.out.println(rs.getString(1));
            System.out.println(rs.getString(2));


        }
     } catch (SQLException ex) {
        ex.printStackTrace();
     }
}
}

问题是此代码的结果异常。我无法知道抛出特定异常的原因。

用户名，密码和服务器名称经过双重检查，确切无误。

目前抛出此异常：

我可以使用integratedSecurity = true运行程序，但我无法从数据库中选择表。我甚至不知道是什么问题，但我已经在SQL Server Management Studio中尝试过，并且它已成功登录。我真的放弃了。首先是将它与我​​的用户和密码连接起来。其次是如何从我的数据库中选择表。请帮我。谢谢。
