布局管理器使用代码，
Class
{
super("Teradata DataPump 1.0"); //设置窗口标题
this.setResizable(false); //禁止改变窗口的大小
//实例化一个布局的类
LoginFrameLayout customLayout = new LoginFrameLayout();
getContentPane().setFont(new Font("Helvetica", Font.PLAIN, 12));
getContentPane().setLayout(customLayout); //设置容器
Icon splash=new ImageIcon("image/logo.jpg"); //加入图片、按钮、文本框等
label_1 = new JLabel(splash);
getContentPane().add(label_1);
pack();
setLocationRelativeTo(getOwner()); //将页面显示在屏幕最中间
/*
*
* 添加一个类，用于布局
*/
