问题描述

请求:

这是我所在地区的 Java 开发人员面临的一个非常常见的问题.我真的被困了很多天.搜索并尝试了很多，阅读文档.阅读所有与 JavaExe 相关的 stackoverflow 问题.请仅在您以前做过类似的事情并有全面答案的情况下回复.我会非常感谢社区！

This is a very common problem faced by Java devs in my locale. I am really stuck for many days on this. Searched and tried a lot, read the docs. read ALL the stackoverflow questions related to JavaExe. Please only reply if you have done similar thing before and have a comprehensive answer. I would be really grateful to the community!

塞纳里奥:

我正在使用 JavaExe 将应用程序作为 系统服务 在桌面 交互式 功能中运行.确切地说，我有一个捕获桌面屏幕截图的应用程序.我希望它在任何用户登录时运行(以管理员身份)，因此没有人可以阻止它.

I am using JavaExe to run an application as system service in desktop interactive capability. To be exact I have an application that captures screenshots of desktops. I want it to run (as admin) on any user login so no one can stop it.

我有一个 myapp.jar、settings.txt 和一个 lib 目录.

I have a myapp.jar, settings.txt and a lib dir.

我搜索了很多，发现 JavaExe 有效(通过观看它的示例)

I have searched alot and found JavaExe works (by watching its examples)

如果有人有更好的方法.请说明.

If anyone has a better way. Please state so.

问题:

根据我的研究，

1. 你必须创建一个类似.exe 的.properties 文件，并在该文件中写入"RunType = 1".

您在主类中定义了一个静态方法:serviceInit()

you define a static method in your main class : serviceInit()

我需要放置任何类或引用/导入吗?怎么样?

Do I need to place any class or reference/import? How?

我下面的代码 works 作为独立的 .jar 和 javaExe.exe.

My code below works as stand alone .jar and in javaExe.exe too.

它现在提供系统服务并由SYSTEM用户运行.但它不能与桌面交互.即它没有显示任何 GUI.

It now does makes a system service and runs by as SYSTEM user. but It is NOT interactive to desktop. i.e its not showing any GUI.

package temp;

import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.JOptionPane;


public class Temp {


    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {


          serviceInit();

    }

    public static boolean serviceInit(){

        new Thread(){
            public void run(){
                Integer i = 0;
                while(i < 999999999){
                    JOptionPane.showMessageDialog(null,i);
                    i++;

                }
            }
        }.start();

        return true;
   }




}

而且我认为将 .jar、lib 目录和 settings.txt 捆绑到一个 .exe 中是不可能的?

And I dont think that bundling the .jar, lib directory and settings.txt into one .exe is possible?

推荐答案

你应该有:

public class MyApp_ServiceManagement
{
    static boolean isMsgToDisplay = false;

    /////////////////////////////
    public static boolean serviceInit()
    {
        (new Thread()
        {
            public void run()
            {
                for(int i=0;i < 6;i++)
                {
                     try { sleep(5*1000); }
                     catch(Exception ex) {}

                     isMsgToDisplay = true;
                }
            }
        }).start();

        return true;
    }

    /// is Data ready to be send to the UI ?
    public static boolean serviceIsDataForUI()
    {
        return isMsgToDisplay;
    }

    /// Data to be send to the UI
    public static Serializable serviceDataForUI()
    {
        isMsgToDisplay = false;
        return "hello, I am an interactive Service";
    }
}

对于 UI 部分:

public class MyApp_TaskbarManagement
{
    /// To show (or not) the icon in tray
    public static boolean taskIsShow()
    {
        return false;
    }

    /// Receive the message from Service
    public static void taskDataFromService(Serializable data)
    {
        JOptionPane.showMessageDialog(null, data);
    }

    /// descr of UI
    public static String[] taskGetInfo()
    {
        return new String[]
            {
                "UI part of Service"
            };
    }
}
