Java swing编程，用什么类实现导航栏？
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);
}
});
}
}
怎样使JSP页面显示另一个页面上生成好的导航栏
1.在页面跳转控制action或者serlvet获取权限
2.写一个header.jsp(需要的页面引入就行) 需要standard.jar和jstl-1.2.jar
%@ taglib prefix="c" uri="" %
核心代码：
!-- 多个权限 --
c:forEach var = "auth" items="${sessionScope.user.auths}"
!-- 单个权限判断 --
c:if test='${auth=="xxx"}'
!-- 写入你权限下的导航--
/c:if
...
/c:forEach
还有其他不清楚的么
