html實現調用jar包

整體思路：html引用URL protocol-本地注冊表key，key對應某一c#寫的exe可執行文件，由exe可執行文件調用cmd，cmd執行jar包。

1、添加注冊表：

Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Print]
"URL Protocol"="d:\\Print\\SupplementPrint.exe"
@="PrintProtocol"
[HKEY_CLASSES_ROOT\Print\DefaultIcon]
@="d:\\Print\\SupplementPrint.exe,1"
[HKEY_CLASSES_ROOT\Print\shell]
[HKEY_CLASSES_ROOT\Print\shell\open]
[HKEY_CLASSES_ROOT\Print\shell\open\command]
@="\"d:\\Print\\SupplementPrint.exe\"\"%1\""

說明：第一行，注冊版本信息，無需關注；2,、注冊表中key值，html中也需要引用這個key“Print”，3、此key對應的exe文件。4、協議名稱。。。

2、編寫C#調用cmd.exe，cmd再調用jar包。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;
using System.Diagnostics;
using System.Text.RegularExpressions;


namespace WindowsFormsApplication1
{
    static class Program
    {
        /// <summary>
        /// 應用程序的主入口點。
        /// </summary>
        [STAThread]
        static void Main()
        {
            //string fullPath = System.Windows.Forms.Application.ExecutablePath;
            //System.Console.WriteLine("Hello world");
            //System.Console.WriteLine(fullPath);
            //string fileName = System.IO.Path.GetFileName(fullPath);
            //string folderPath = fullPath.Substring(0,fullPath.Length-fileName.Length);
            //string cmd = "start " + folderPath + " jre/bin/javaw - jar " + folderPath + "zte-mes-supplementPrint-javaFX-0.0.1-SNAPSHOT.jar";
            //System.Console.WriteLine(cmd);
            RunCmd(cmd);
        }

        private static void RunCmd(string cmd)
        {
            Process p = new Process();
            p.StartInfo.FileName = "cmd.exe";
           
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true;
            //string str = Console.ReadLine();
            string str = @"java -jar c:\\Users\\10244896\\Desktop\\print\\zte-mes-supplementPrint-javaFX-0.0.1-SNAPSHOT.jar" + "&exit";
            str = str.Trim().TrimEnd('&');
            p.Start();
            p.StandardInput.WriteLine(str);

            p.StandardInput.AutoFlush = true;
            //p.StartInfo.Arguments = "java -jar c:\\Users\\10244896\\Desktop\\print\\zte-mes-supplementPrint-javaFX-0.0.1-SNAPSHOT.jar";
            
            
            p.WaitForExit();
           // throw new NotImplementedException();
        }
    }
}

說明：僅關注runCmd方法即可。

3、編寫html

<a href="Print://hello">Print</a>
