一个测试JDBC连接SqlServer的Java类

import java.sql.*;
public class TestForJDBC {
public static void main(String[] args){
  String url="jdbc:sqlserver://localhost:1433;DatabaseName=EB";
  String userName="sa";
  String password=""; //密码自己根据情况而定

  try{
  System.out.println("before load driver");
  Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
  System.out.println("after load driver sucessful");
  }catch(ClassNotFoundException e){
  System.err.print("fail to load driver");
  }
  try{
  System.out.println("before connect to database");
  Connection conn = DriverManager.getConnection(url,userName,password);
  System.out.println("connect database sucessfull");
  }catch(Exception e){
  e.printStackTrace();
