java - 如何分发 java GUI 构建器项目

Question

这个问题已经有答案了:

Java Path ImageIcon URL .JAR (1 个回答)

已关闭 8 年前。

目前，我分发其他内容以从 java 运行时环境获取“发生 Java 异常”。我该如何将其作为 .jar 正确分发？

正如您的问题下面的评论中所指出的，错误的最明显原因是您所依赖的资源是使用绝对地址引用的。这基本上意味着除非客户端具有与您的开发机器完全相同的配置，否则您的程序将无效。

为了使您的应用程序可分发，您应该将资源打包到 JAR 文件中。这个问题有一些有用的提示:

Java Path ImageIcon URL .JAR

顺便说一句，发生异常时引发的堆栈跟踪在诊断错误时非常有值(value)。您绝对应该将其与任何进一步的问题一起发布。不要用这样的代码吞掉异常:

try {
    doSomethingWhichMightFail();
} catch(Exception e) {

}

除非您完全确定该异常无关紧要(这种情况非常罕见!)。
