c)getClass().getResourceAsStream("imgs")

c) getClass().getResourceAsStream("imgs")

但以上都不对我有用.

请建议我如何在其中存储图像 'src/main/resources/imgs'

推荐答案

您应该尝试将图像存储到运行时不可用的位置.构建并捆绑了应用程序后，src文件夹将不存在.

You should be trying to store images into a location that won't be available at runtime. The src folder won't exist once your application is built and bundled.

您有很多可用的选择...

You have lots of options available to you...

在user.home中创建一个目录并将图像存储在此处，但这确实会使事情变得混乱...

Create a directory in user.home and store the images there, but this does tend to clutter things up...

String format = ...
String home = System.getProperty("user.home");
String path = home + File.separator + "downloadedImages";
File fPath = new File(fPath);
if (fPath.exists() || fPath.mkdirs()) {
    File imageFile = new File(fPath, "image");
    BufferedImage img = ImageIO.read(...);
    ImageIO.write(img, format, imageFile);
}

您可以...

使用

You Could...

Create a temporary file using something like createTempFile(String prefix, String suffix), which will allow to you to write the image out and then read it back it when you need it...

例如...

String format = ...;
File tmp = File.createTempFile("name", "img");
BufferedImage img = ImageIO.read(...); // Download the image...
ImageIO.write(img, format, tmp); // Write the image to the tmp folder...

// Deal with the image as you need...
