I have assigned an extension name for my files called *.XSCA. I would like to read the content of this file when the user click on it using my executable jar file to open it. How can I do that?

推荐答案

假设您在Windows下工作:

assuming you work under windows:

• 创建一个调用您的jar的批处理文件(* .bat)(应该类似于"java -jar yourJar.jar")
• 右键单击您类型的文件，转到属性"，然后将打开文件的程序更改为该批处理文件
• 让批处理文件将文件位置作为参数传递给您的jar

您可以使用任何文本编辑器编写批处理文件.使用谷歌找出如何.它将只是您的jar的包装，您可以在Windows中将其与文件扩展名类型相关联.

You can write a batch-file with any text-editor. Use google to find out how. It will just be a wrapper for your jar that you can associate in windows with your file-extension-type.

好的，一步一步来

那是您的Java程序(将它作为可运行的jar与Eclipse一起导出):

That's your Java program (export it with Eclipse as a runnable jar):

public class ExtensionOpener {

    public static void main(String[] args) throws InterruptedException {

        System.out.println("args:");

        for(String arg: args) 
            System.out.println(arg);

        Thread.sleep(3000);
    }
}

这是批处理文件(只需将其另存为例如 your-starter.bat ):

That's the batch-file (just save it as e.g. your-starter.bat):

@echo run bat
java -jar C:\Users\Thomas\Desktop\FileOpener.jar -file -%1

现在，在文件( your.fileextension )上单击鼠标右键，然后转到属性并将其与批处理文件关联.就是这样.

Now click right on your file (your.fileextension) and go to properties and associate it with the batch-file. That's it.
