Eclipse - 导出时程序中断

Question

最近几天我一直在做一个 Java 项目，我决定将它导出到一个 jar 中进行测试。该程序在 Eclipse 中运行良好，但在 jar 文件中被破坏。此外，所有资源都位于项目内。另请注意，这不是整个项目，如果需要，请索取其他代码（很多）。

编辑：

程序现在确实在左侧显示图像，在底部显示按钮，并在顶部显示欢迎。仍然没有显示左侧文本文件的内容。

这是它在 Eclipse 中的样子：

这是 jar 文件中的样子（所有按钮都不起作用）：

这是该类的代码：

我该如何解决这个问题？感谢您的帮助。

如果它在 Eclipse 中可以正常工作，但在导出到 jar 时却不行，则可能是所需的库有问题。您可以尝试更改导出到 jar 的设置。
