事实上，我也遇到过这个问题。我通过为我的jar文件创建.bat运行程序来解决这个问题。

代码如下:

class FileHandler{
   public static File create_CMD_Rnner(){
      int exitCode = -1625348952;
      try{
           File runner = new File(Main.batName);
           PrintWriter printer = new PrintWriter(runner);
           printer.println("@echo off");
           printer.println("title " + Main.applicationTitle);
           printer.println("java -jar " + Main.jarName + " " + Main.startCode );
           printer.println("PAUSE");
           printer.flush();
           printer.close();
           return runner;
       }catch(Exception e){
           System.err.println("Coudln't create a runner bat \n exit code: " + exitCode);
           System.exit(exitCode);
           return null;
       }
   }
}

然后在你的主应用程序类中这样做:

public class Main{
    static String jarName = "application.jar";
    static String applicationTitle = "java Application";
    static String startCode = "javaIsTheBest";
    static String batName = "_.bat";


    public static void main(String args[]) throws Exception{
        if(args.length == 0 || !args[0].equals(startCode)) {
            Desktop.getDesktop().open(FilesHandler.create_CMD_Rnner());
            System.exit(0);
        }else{
            //just in case you wanted to hide the bat
            deleteRunner();
            // Congratulations now you are running in a cmd window ... do whatever you want
            //......
            System.out.println("i Am Running in CMD");
            //......
            Thread.sleep(84600);
        }
    }


    public static void deleteRunner(){
        File batRunner = new File(batName);
        if(batRunner.exists()) batRunner.delete();
    }
}

请注意

这段代码(我的代码)只适用于jar文件，而不是类文件。 jar文件必须与Main类的字符串“jarName”同名

最简单的方法可能是升级或重新安装Java运行时环境(JRE)。

或:

Open the Windows Explorer, from the Tools select 'Folder Options...' Click the File Types tab, scroll down and select JAR File type. Press the Advanced button. In the Edit File Type dialog box, select open in Actions box and click Edit... Press the Browse button and navigate to the location the Java interpreter javaw.exe. In the Application used to perform action field, needs to display something similar to C:\Program Files\Java\j2re1.4.2_04\bin\javaw.exe" -jar "%1" % (Note: the part starting with 'javaw' must be exactly like that; the other part of the path name can vary depending on which version of Java you're using) then press the OK buttons until all the dialogs are closed.

这是从这里偷来的:http://windowstipoftheday.blogspot.com/2005/10/setting-jar-file-association.html

步骤:

1.)在谷歌上搜索“Java SE Runtime Environment”:https://www.google.com/search?q=Java+SE+Runtime+Environment

2.)在你的电脑上安装合适的版本

如果你需要分发你的.jar文件，让它可以在其他人的Windows电脑上运行， 你可以在命令提示符中创建一个简单的.bat文件:

java -jar MyJavaTool.jar

并将.bat文件放在与.jar文件相同的目录中。

有一种方法不需要用户在他的PC上做改变。runtime . getrtime .exec()允许我们启动cmd.exe并在其中执行命令。因此，当用户单击.jar文件时，java程序可以在命令提示符下自行运行。

public static void main(String[] args) throws IOException {
    if(args.length == 0) {
        Process p = Runtime.getRuntime().exec("cmd.exe /c start java -jar " + (new File(NameOfClass.class.getProtectionDomain().getCodeSource().getLocation().getPath())).getAbsolutePath() + " cmd");
    } else {
        //code to be executed
    }
}

我正在运行Windows 7 x64，无法使用任何这些修复程序。

这条对我来说还是有用的:

你可以下载一个包含要运行的.bat文件的存档文件，但请检查实际的javaw.exe!!!!的路径
