 建立数据库连接，取得Connection对象.例如:

  String url="jdbc:oracle:thin:@localhost:1521:orcl";
  String user="scott";
  String password="tiger";
  Connection conn=DriverManager.getConnection(url,user,password);
 
  //Sql Server7.0/2000数据库
  String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs";
  String user="sa";
  String password="";
  Connection conn=DriverManager.getConnection(url,user,password);
 
  //DB2数据库
  String url="jdbc:db2://localhost:5000/sample";
  String user="amdin"
  String password=-"";
  Connection conn=DriverManager.getConnection(url,user,password); 
  //Sybase数据库
  String url="jdbc:sybase:Tds:localhost:5007/tsdata";
  Properties sysProps=System.getProperties();
  SysProps.put("user","userid");
  SysProps.put("password","user_password");
  Connection conn=DriverManager.getConnection(url,SysProps);
 
  //MySQL数据库
  String url="jdbc:mysql://localhost:3306/testDB?user=root&password=root&useUnicode=true&characterEncoding=gb2312";
