在 .jar 中包含其他文件

Question

Ok, so I am experimenting using a java program to open up HTML documents. So, what I have is a website already made. I have the website in a separate folder called " website" that is next to the src file. I want to then take the src folder and the website folder and put them into the same .jar file so you can then send the .jar file to any computer and when you run it, it opens the website. I'm not sure if I worded that well, so just let me know if you need more specifications.

Here is the code that opens the HTML file.

import java.awt.Desktop;
import java.io.File;
import java.io.IOException;

public class BrowserTest {
    public static void main(String[] args) {
        String url = "framePage.html";
        File htmlFile = new File(url);
        try {
            Desktop.getDesktop().browse(htmlFile.toURI());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

UPDATED CODE

import java.awt.Desktop;
import java.io.IOException;
import java.net.URISyntaxException;
import java.net.URL;

public class BrowserTest {
    public static void main(String[] args) {
        System.out.println(BrowserTest.class.getResource("/Website/framePage.html"));
        URL url = BrowserTest.class.getResource("/Website/framePage.html");


        try {
            Desktop.getDesktop().browse(url.toURI());
        } catch (IOException | URISyntaxException e) {
            e.printStackTrace();
        }
    }
}

Answer 1

Using a command line (eg CMD on windows or Terminal for unix-based OS), you can create .jar archives using the following command:
jar cf myJar.jar *
Where myJar.jar is the output file. The * will archive everything in the current directory so in the console navigate to the directory with all the files before you use this command.

Answer 2

Simply specify it during your jar command(assuming your running from inside src):

jar cvf BrowserTest.jar BrowserTest.class ../website

Source: https://docs.oracle.com/javase/tutorial/deployment/jar/build.html

After you have that structure, you can retrieve the files like so:

// Get current classloader
ClassLoader cl = this.getClass().getClassLoader();
// Create page class
Page customPage  = new Page(cl.getResource("website/page1.html"));

Update

Included running code on Github

If you do not need an webserver, just do like that:

1. Create a simple Maven project
2. Copy your website to src/main/java folder. It will be included in the jar automatically.
3. Write some code to extract your website from classpath to containing jar folder.

You have to embedded an web server inside your jar. There was multiple way to do that. But I recommend you to try Spring Boot.
