将资源（图像，声音等）嵌入到Java项目中，然后使用这些资源 [英] Embedding resources (images, sound bits, etc) into a Java project then use those resources

问题描述

我已经搜索了在java项目（使用Eclipse v3.6.0）中嵌入资源的方法，然后使用控件中的嵌入式资源（例如， JLabel ） 。我已经看到了从文件系统引用资源的方法。一旦开发了项目，我想将应用程序作为可执行文件发布。应该注意，这些可执行文件将被部署/启动到Windows，* NIX和Linux平台。

I have searched for a method of embedding a resource in a java project (using Eclipse v3.6.0) then using that embedded resource within a control (e.g., JLabel). I have seen methods of referencing resources from the file system. Once the project has been developed I would like to publish the application as an executable. It should be noted these executables will be deployed/launched to Windows, *NIX, and Linux platforms.

我知道这可以在Visual Studio世界中完成，但是在Java / Eclipse IDE中如何做到这一点非常陌生。作为一个侧面问题，如何让Eclipse将该项目创建为可执行文件，以便可以启动？

I know this can be done in the Visual Studio world, but I'm very unfamiliar how to do this in Java/Eclipse IDE. As a side question, how do I get Eclipse to create the project as a executable so it can be launched?

非常感谢任何帮助。

更新1：

根据 BalusC的回复，我想分享我必须解决我的问题的代码。我的课程包含 Viking.Test 的包，然后我将图像文件放在$ codeViking.Test.Resources 。这一切都在Eclipse中完成，将图像导入到项目中。

Based upon BalusC's response, I wanted to share the code I have to resolve my problem. My classes are under the package of "Viking.Test" and then I placed the image file under the package "Viking.Test.Resources". This is all done within Eclipse to import the image into the project.

1. 我通过右键单击项目导入图像


2. 选择包含导入图像的文件夹


3. 已选择 c code code code code code code code $不要更改任何选项，点击完成

1. I imported the image by right-clicking on the Project -> Import -> General/File System for the import source.
2. Selected the folder which contained the image to import
3. Selected "Project/src/Viking/Test/Resources" for the 'Into folder' parameter
4. Didn't change any of the options and clicked "Finished"

在源文件中，我添加了以下内容将图像插入 JLabel （ LblLogo ）

In the source file I added the following code to insert the image into a JLabel (LblLogo)

try
{
  ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
  InputStream input = classLoader.getResourceAsStream(
    "Viking/Test/Resources/MyImage.jpg");
  Image logo = ImageIO.read(input);
  LblLogo = new JLabel( new ImageIcon( logo ) );
  LblLogo.setBounds(20, 11, 210, 93);
  getContentPane().add(LblLogo);
}
catch ( IOException e ) {  }

推荐答案

只需将这些资源放在源码/包结构中，然后使用 ClassLoader＃getResource（） 或 getResourceAsStream（） 通过完全限定的包路径从类路径中获取它们作为 URL 或 InputStream 。

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
InputStream input = classLoader.getResourceAsStream("/image.gif");
// ...

或者如果它与当前类在同一个包中你也可以获得如下：

Or if it is in the same package as the current class, you can also obtain it as follows:

InputStream input = getClass().getResourceAsStream("image.gif");

问题是，如何让Eclipse将项目创建为可执行文件，以便可以启动。

As a side question, how do I get Eclipse to create the project as a executable so it can be launched.

右键单击Java项目>导出> Runnable JAR文件。
