java实现桌面程序开机自启动

问题：

最近用java写一个桌面闹钟程序，需要实现开机自启动功能

解决办法：

jna官网：https://github.com/java-native-access/jna?tab=readme-ov-file

使用jna库可以轻松实现

下载jna-5.15.0.jar和jna-platform-5.15.0.jar这两个库文件，加入到工程

下面给出是工具类

package org.lionsoul.dclock.util;


import com.sun.jna.platform.win32.Advapi32Util;
import com.sun.jna.platform.win32.WinReg;

public class RegistryUtil {

    public static void addStartup(String name, String path){

            Advapi32Util.registrySetStringValue(WinReg.HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Run", name, path);
    }

    public static void deleteStartup(String name){
        Advapi32Util.registryDeleteValue(WinReg.HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Run", name);
    }

    public static boolean isStartWithSystem(String name) {

        String dhRegister = getReg("Software\\Microsoft\\Windows\\CurrentVersion\\Run", name);

//        String dClock = WinRegistry.getString(WinRegistry.HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Run", name);
        System.out.println("isStartWithSystem dhRegister :" + dhRegister);
        if (dhRegister != null && dhRegister.length() > 0){
            return true;
        }
        return false;
    }





    public static String getReg(String key, String valueName) {
        String value;

        try {
            value = Advapi32Util.registryGetStringValue(WinReg.HKEY_CURRENT_USER, key, valueName);
        } catch (Exception e) {
            value = "";
        }

        return value;
    }

}

调用的代码：

if (RegistryUtil.isStartWithSystem(__APP_NAME) ) {
    RegistryUtil.deleteStartup(__APP_NAME);
} else {
	RegistryUtil.addStartup(__APP_NAME, System.getProperty("user.dir") + "\\DHClock.cmd");
}
