Java映像未出现在JAR文件中 [英] Java images not appearing in JAR file

问题描述

这里我怎么称呼图像

Icon logoOne = new ImageIcon("logo.png");
// LOGO
JLabel imageLogo = new JLabel(logoOne); 
imageLogo.setPreferredSize(new Dimension(200, 50));

它只是添加到JFrame的面板中，在Eclipse中运行时工作正常，但在Eclipse中运行时却不显示

Its just added to a panel in a JFrame and works fine when running in eclipse but doesnt show up when exported to JAR.

任何人都可以帮忙吗？

推荐答案

导出时您的JAR文件中，您必须确保还将图像文件包含在JAR文件中。例如：如果您有一个名为 res的文件夹，其中包含图像，则必须选中此文件夹之前的复选框，以确保此文件夹和图像都包括在内。

When exporting your JAR file, you've to make sure you're also including the image files in your JAR file. For example: If you have a folder called 'res' containing the images, you have to check the checkbox before this folder in order to make sure this folder, and the images are being included.

您可能想添加一些故障排除代码。例如：如果此图像文件存在，请添加一些在控制台中打印的代码。导出您的JAR文件，通过控制台/终端运行您的JAR并检查结果。如果显示的图像不存在，则说明导出的JAR文件存在问题。

You might want to add some trouble shooting code. For example: Add some code that prints in the console if this image file exists. Export your JAR file, run your JAR via the console/terminal and check the result. If this shows you the image doesn't exists, you know it's a problem with your exported JAR file.

您可能希望尝试将其作为资源流到达该图像，尝试以下代码示例：

You might want to try reaching the image as a resource steam, give the following code sample a try:

java.net.URL logoOneUrl = getClass().getResource("logo.png");
Icon logoOne = new ImageIcon(logoOneUrl );
