Question

我已将我的应用程序部署到jar文件。我想在我的应用程序的资源文件夹中生成和存储PDF，Everything在开发中对我有用，但是当我部署时，我在实时应用程序中出错了

以下是我的代码

        URL url = this.getClass().getResource("/templates");
        parentDirectory = new File(new URI(url.toString()));
        OutputStream outputStream = new FileOutputStream(parentDirectory.toString()+"/"+quoteNumber+".pdf");

当我从Eclips运行我的应用程序但是我在服务器中部署应用程序WAR文件时，一切正常并且成功创建了PDf文件我得到了这个错误

我的错误完整日志正在关注

Answer 1

您应该使用

getResourceAsStream(...);

当资源捆绑为jar / war或任何其他单个文件包时。

看到的是，jar是一个单独的文件（有点像zip文件），它们将大量文件放在一起。从Os的pov，它是一个单独的文件，如果你想访问文件的一部分（你的图像文件），你必须将它用作流

Answer 2

使用

创建OutputStream

OutputStream os = this.getClass()
    .getClassLoader()
    .getResourceAsStream("/templates/" + quoteNumber + ".pdf");

您希望将pdf存储在jar中，这与在使用OS文件系统的本地环境（例如使用Eclipse）中运行时不同。

java.lang.IllegalArgumentException：URI不是分层的（在已部署的应用程序中）
