查看“Java任务：软件整体组装”的源代码

==商品展示页面==
===在商品展示页面中添加成员信息===
在BooklistForm类中添加成员变量：
 private User user = null;

并给BookListForm添加一个User参数的构造方法
 <nowiki>public BookListForm(User user) {
		this.user = user;		
		initialize();
		setCenter(frame);
		initUser();
}

	/**
	 * 初始化页面显示的用户信息
	 */
	private void initUser() {
		if(user != null) {
			lblName.setText(lblName.getText() + "，" + user.getName());
			lblCity.setText(lblCity.getText() + user.getCity());
		} 
	}</nowiki>

==用户登陆界面==
在UserForm的‘登陆’按钮的监听器上增加如下红框内代码：

 [[文件:java9-38.png|700px]]

==用户退出机制==
在商品展示页面增添如下‘退出’标签：

[[文件:java9-39.png]]

并为该标签增添事件监听器：lblLogout.addMouseListener(new LogoutMouse());

  <nowiki>/*LogoutAction:退出账号的监听器
     * 
     */
    private class LogoutMouse implements  MouseListener{
    	public LogoutMouse(){
    		
    	}
    	@Override
    	public void mousePressed(MouseEvent e){}
		public void mouseClicked(MouseEvent e){
			if(e.getButton()==MouseEvent.BUTTON1) {
				UserForm u = new UserForm();
				u.setVisible(true);
				frame.dispose();
			}
		}
		public void mouseReleased(MouseEvent e){}
		public void mouseEntered(MouseEvent e){}
		public void mouseExited(MouseEvent e){}
    }</nowiki>
