我试图将图像从本地目录加载到ImageIcon(URL)中.该图像文件是从.jar文件访问的.jar文件名为swingex.jar.项目结构类似

I trying to load image from local directory into ImageIcon(URL).This images files access from .jar file.The jar file name is swingex.jar.The project structure like

F:/>SwingExample
         |
         |___src
         |
         |___build.xml
         |
         |___lib
               |
               |___swingsex.jar(generated through build.xml file)
         |
         |__resource
                   |
                   |_____images
                            |
                            |___logo1.png

如何读取logo1.png文件?

我想喜欢这个

1. file:///f://resources//images//processedimages//返回null

ClassLoader.getSystemResource("resources/images/processedimages/"); 返回null

更新:-我仍然有问题.因为我在SwingExample上创建了jar文件并排除了resource/images目录.当运行jar文件时，它无法识别resource/images文件夹.但是我通过Eclipse运行了SwingExample项目，代码运行正常.代码是

Update :- Still i have problem.because i created jar file on SwingExample and excludes the resource/images directory .When run the jar file its not recognized the resource/images folder.But i ran the SwingExample Project through eclipse it working fine.The code is

File directory = new File (".");
Image img = null;
String path="";
URL url=null;
try {
  path=directory.getCanonicalPath()+"/resources/images/logo1.png";
               img = ImageIO.read(new File(getDefaultImageUploadPath());

} catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
}
        return new ImageIcon(img);

推荐答案

URL imgURL =
   new File( "F:/SwingExample/resource/images/logo1.png" ).toURI().toURL();

但是我建议将资源放入src.

But I suggest to put resource into src.

如果资源位于src中，则可以通过类加载器轻松访问它们.

If resource is in src, you may access them by class loader easily.

getClassLoader().getResourceAsStream( "resource/images/logo1.png" );
