原理很简单:robot类模拟键盘输入,快捷键打开微信,搜索好友,把发送内容发送的粘贴板实现。

程序源码

package com.cloudansys.test;

import java.awt.*;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.StringSelection;
import java.awt.datatransfer.Transferable;
import java.awt.event.KeyEvent;

public class T6 {
   
   

    public static void main(String[] args) throws InterruptedException {
   
   
        // 好友昵称
        String friendNickName = "不器";
//        String friendNickName = "文件传输助手";

        searchMyFriendAndSend(friendNickName);
    }

    private static void searchMyFriendAndSend(String friendNickName) throws InterruptedException {
   
   
        // 创建Robot对象
        Robot robot = null;
        try {
   
   
            robot = new Robot();
        } catch (AWTException e) {
   
   
            e.printStackTrace();
        }
        //打开微信 Ctrl+Alt+W
        assert robot != null;
        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_ALT);
        robot.keyPress(KeyEvent.VK_W);
        //释放Ctrl按键,像Ctrl,退格键,删除键这样的功能性按键,在按下后一定要释放
        robot.keyRelease(KeyEvent.VK_CONTROL);
        robot.keyRelease(KeyEvent.VK_ALT);

        // 该延迟不能少,否则无法搜索
        robot.delay(1000);

        // Ctrl + F 搜索指定好友
        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_F);
        robot.keyRelease(KeyEvent.VK_CONTROL);

        // 将好友昵称发送到剪切板
        Clipboard clip = Toolkit.getDefaultToolkit().getSystemClipboard();
        Transferable tText = new StringSelection(friendNickName);
        clip.setContents(tText, null);
        // 以下两行按下了ctrl+v,完成粘贴功能
        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_V);
        robot.keyRelease(KeyEvent.VK_CONTROL);
        robot.delay(1000);
        robot.keyPress(KeyEvent.VK_ENTER);

        // 发送消息
        sendMsg();
    }

    private static void sendMsg() throws InterruptedException {
   
   
        String[] mottoes = {
   
   
                "我只爱你四天,春天夏天秋天冬天!",
                "我只爱你三天,昨天,今天,明天!",
                "我只爱你两天,白天,黑天!",
                "我只爱你一天,每一天!",
                "[玫瑰]爱你么么哒!",
                "[呲牙][坏笑]",
                "[奸笑]"
        };
        for (String motto : mottoes) {
   
   
            sendOneMsg(motto);
        }
        Thread.sleep(2000);

        sendOneMsg("[得意]就问你,腻不腻害!");
    }

    private static void sendOneMsg(String msg) {
   
   
        Clipboard clip = Toolkit.getDefaultToolkit().getSystemClipboard();
        Transferable tText;
        Robot robot = null;
        try {
   
   
            robot = new Robot();
        } catch (AWTException e) {
   
   
            e.printStackTrace();
        }
        //延迟十秒,主要是为了预留出打开窗口的时间,括号内的单位为毫秒
        assert robot != null;
        robot.delay(500);
        tText = new StringSelection(msg);
        clip.setContents(tText, null);
        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_V);
        robot.keyRelease(KeyEvent.VK_CONTROL);
        robot.delay(500);
        robot.keyPress(KeyEvent.VK_ENTER);
        robot.delay(500);
    }

}
