Java有Stop按钮退出正在运行的程序
1. 运行界面的主程序，注意 main4.run调用真正执行任务的程序
importjava.awt.FlowLayout;
importjava.awt.event.ActionEvent;
importjava.awt.event.ActionListener;
import java.io.IOException;
importjavax.swing.JButton;
import javax.swing.JFrame;
importjavax.swing.JPanel;
public class Test extends JFrame {
SheThread thread = null;
public Test() {
try {
createFrame();
}
catch(Exception e) {
e.printStackTrace();
}
}
private void createFrame() throws IOException {
JPanel jp = new JPanel(new FlowLayout());
this.add(jp);
JButton jbStart = new JButton("start ");
JButton jbEnd = new JButton("stop");
//jp.add(jbStart);
jp.add(jbEnd);
this.setSize(300, 100);
this.setVisible(true);
this.setResizable(false);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jbStart.addActionListener(new ActionListener() {
public voidactionPerformed(ActionEvent e) {
if (thread != null)
thread.stop();
thread = new SheThread();
thread.start();
}
});
jbEnd.addActionListener(new ActionListener() {
public voidactionPerformed(ActionEvent e) {
if (thread != null)
thread.stop();
System.exit(0);
thread = null;
}
});
//需要执行的主程序
Main4.run();
}
public static void main(String[] args) {
new Test().show();
}
}
class SheThread extends Thread {
public SheThread() {
}
public void run() {
while (true) {
try {
sleep(1000);
} catch (InterruptedException e) {
}
System.out.println("this is a test!");
}
}
}
2. 执行代码的真正程序
public class Main4 {
public static int Sub_ID = 0;
public static String cliuid_2 = "";
public static String unedname = "";
public static String search_method = "";
public static int rawID_Total = 0;
public static JTextField filename = new JTextField("c:/p.xls");
public static String URL = "";
public static JFrame frame = new JFrame();
public static PrintWriter writer;
public static DB db;
public static String str_SQL;
public static String str_trim = "0000";
public static String cliuid_2_unedname = "";
public static String dirName = "";
public static String fileName_final = "";
……
……
public static void run() throws IOException {
try {
input();
Sheet sheet;
Workbook book;
try {
book = Workbook.getWorkbook(new File(filename.getText()));
sheet = book.getSheet(0);
rawID_Total = sheet.getRows(); // 获取行数
for (int i = 1; i < rawID_Total; i++) {
readExcel(sheet, i);
initSearch(unedname, "bingSearch");
Sub_ID = 0;
}
book.close();
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e2) {
JOptionPane.showMessageDialog(null, e2.getMessage());
}
System.exit(0);
}
