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
