直接cmd 窗口执行如下命令即可

netstat -ano | findstr :8080
taskkill /F /PID <PID>

简简单单的两个指令,总是记不住,也懒的记, 每次端口冲突的时候, 都是直接查百度,很苦逼, 如果有一个程序,直接输入端口号,点击按钮直接杀死进程,岂不爽歪歪.

跟我一起制作一个屠猫的程序吧!

环境: 默认你已经安装了jdk

第一步: 在某个盘符里，新建一个文件夹, 并将以下文件KillTomcatProcess.java放到文件夹中
KillTomcatProcess.java

import javax.swing.*;  
import java.awt.*;  
import java.awt.event.ActionEvent;  
import java.awt.event.ActionListener;  
import java.io.BufferedReader;  
import java.io.InputStreamReader;  public class KillTomcatProcess extends JFrame {  private JTextField portField;  private JButton killButton;  public KillTomcatProcess() {  setTitle("Tomcat Port Killer");  setSize(300, 150);  setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);  setLocationRelativeTo(null); // Center the window  setLayout(new FlowLayout());  JLabel label = new JLabel("Enter Tomcat Port:");  add(label);  portField = new JTextField(10);  add(portField);  killButton = new JButton("Kill Process");  killButton.addActionListener(new ActionListener() {  @Override  public void actionPerformed(ActionEvent e) {  String port = portField.getText().trim();  if (!port.isEmpty()) {  try {  String pid = findProcessIdByPort(port);  if (pid != null) {  killProcess(pid);  JOptionPane.showMessageDialog(KillTomcatProcess.this, "Process with PID " + pid + " killed successfully!");  } else {  JOptionPane.showMessageDialog(KillTomcatProcess.this, "No process found for port " + port);  }  } catch (Exception ex) {  JOptionPane.showMessageDialog(KillTomcatProcess.this, "Error: " + ex.getMessage());  }  } else {  JOptionPane.showMessageDialog(KillTomcatProcess.this, "Please enter a port number.");  }  }  });  add(killButton);  setVisible(true);  }  private String findProcessIdByPort(String port) throws Exception {  String line;  Process process = Runtime.getRuntime().exec("cmd /c netstat -aon | findstr " + port);  BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));  while ((line = reader.readLine()) != null) {  if (line.contains("LISTENING")) {  String[] parts = line.split("\\s+");  return parts[parts.length - 1];}  }  return null;  }  private void killProcess(String pid) throws Exception {  Runtime.getRuntime().exec("cmd /c taskkill /F /PID " + pid);  }  public static void main(String[] args) {  new KillTomcatProcess();  }  
}

第二步：当前文件夹下打开cmd，将java文件编译成可执行文件javac KillTomcatProcess.java

尝试执行编译后的文件java KillTomcatProcess 窗口能够正常弹出即可，

现在输入端口能够立刻将进程杀死，但是操作起来一点也不方便

第三步： 在当前文件夹下，创建一个KillTomcat.bat文件，文件内容如下

KillTomcat.bat

@echo off  
java KillTomcatProcess  
pause

鼠标右键，将该文件发送到桌面快捷方式，这样我们桌面上只有屠猫的图标，非常简洁

最终运行效果
