Maven package resources文件夹位于最终jar的src/main下

默认情况下,Maven根据 Standard Directory Layout . 虽然最后的罐子有问题。

因为我正在从src/main/resources文件夹加载图像,如下所示:

class.getResourceAsStream("/main/resources/image/"+ imageName));

在最后一个jar中,images文件夹不在主文件夹下。我以前把资源文件夹放在外面 src 文件夹和一切似乎还好,但我想按照标准的目录布局,所以我把它。在一切正常工作之前,请使用:

class.getResourceAsStream("/image/"+ imageName));

这是当前的目录布局:

只有那个代码现在有效 class.getResourceAsStream("/main/resources/image/"+ imageName));

你能告诉Maven如何在最终jar上打包resources文件夹吗?
