可以在JMenuItem上设置图片和背景颜色。具体给你个例子你看看：（设置方法见注释）

import java.awt.BorderLayout

import java.awt.Color

import java.awt.event.ActionEvent

import java.awt.event.ActionListener

import javax.swing.ImageIcon

import javax.swing.JButton

import javax.swing.JFrame

import javax.swing.JMenu

import javax.swing.JMenuBar

import javax.swing.JMenuItem

import javax.swing.JSeparator

public class E extends JFrame implements ActionListener{

JButton close=null

JMenuItem mopen=null

JMenuItem mclose=null

JMenuItem mexit=null

E(){

close=new JButton("退出")

add(close,BorderLayout.SOUTH)

close.addActionListener(this)

JMenuBar jmb=new JMenuBar()

JMenu file=new JMenu("文件")

mopen=new JMenuItem("打开")

ImageIcon logoing=new ImageIcon("black_bishop.gif") //这里定义一个Icon图片

mopen.setIcon(logoing) //这里设置Icon图片到MenuItem

mopen.setBackground(Color.YELLOW)//这里设置MenuItem的背景色为黄色

mclose=new JMenuItem("关闭")

mexit=new JMenuItem("退出")

JSeparator separator=new JSeparator()

file.add(mopen)

file.add(mclose)

file.add(separator)

file.add(mexit)

jmb.add(file)

setJMenuBar(jmb)

mclose.addActionListener(this)

mexit.addActionListener(this)

setSize(300, 300)

setVisible(true)

setDefaultCloseOperation(DISPOSE_ON_CLOSE)

}

public static void main(String[] args) {

new E()

}

public void actionPerformed(ActionEvent ae) {

if(ae.getSource()==close){

dispose()

}else if(ae.getSource()==mclose){

dispose()

}else if(ae.getSource()==mexit){

dispose()

}

}

}
