Java swing編程，用什么類實(shí)現(xiàn)導(dǎo)航欄？

import java.awt.Button;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JFrame;

public class Demo {

public static void main(String[] args) {

Demo demo = new Demo();

demo.run();

}

public void run() {

JFrame frame = new JFrame("title1");

frame.setLayout(null);

frame.setBounds(10, 10, 500, 300);

Button button = new Button("click");

button.setBounds(15, 15, 200, 100);

frame.add(button);

frame.setVisible(true);

button.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

JFrame frame = new JFrame("title2");

frame.setLayout(null);

frame.setBounds(20, 20, 300, 100);

frame.setVisible(true);

}

});

}

}

怎樣使JSP頁(yè)面顯示另一個(gè)頁(yè)面上生成好的導(dǎo)航欄

1.在頁(yè)面跳轉(zhuǎn)控制action或者serlvet獲取權(quán)限

2.寫一個(gè)header.jsp(需要的頁(yè)面引入就行)?需要standard.jar和jstl-1.2.jar

%@?taglib?prefix="c"?uri=""?%

核心代碼：

!--?多個(gè)權(quán)限?--

c:forEach?var?=?"auth"?items="${sessionScope.user.auths}"

!--?單個(gè)權(quán)限判斷?--

c:if?test='${auth=="xxx"}'

!--?寫入你權(quán)限下的導(dǎo)航--

/c:if

...

/c:forEach

還有其他不清楚的么
