如何将文件从另一个非Java程序输出到Java jar文件的resources文件夹中

[英]How to output a file from another non java programme into the resources folder of a java jar file

原文 2016-11-24 11:05:32 4 1 java/ swing

I have an R script that outputs html and dumps it in a directory of my choosing. 我有一个R脚本，可以输出html并将其转储到我选择的目录中。 I also have a java Swing application with a WebView component that allows me to see the html from within the Swing application. 我还有一个带有WebView组件的Java Swing应用程序，它使我能够从Swing应用程序中查看html。

This works OK on most computers but because the outputted html contains a base64 image, for some reason the image cannot be viewed from the Swing WebViewer on certain operating systems(although the rest of the html can-I can see the images on my mac but not on Windows 2003). 这在大多数计算机上都可以正常运行，但是由于输出的html包含base64图像，由于某些原因，在某些操作系统上无法从Swing WebViewer查看该图像（尽管html的其余部分可以，但我可以在Mac上看到这些图像，但是不适用于Windows 2003）。

I think this is a problem relating to the security of a java programme accessing resources outside of the programme that maybe permissions are not set up for or something. 我认为这是一个与Java程序的安全性有关的问题，该Java程序访问程序外部的资源（可能未设置权限）。

To simplify things I want to dump the html in resources that are local to the Swing application (ie in a resources folder) that would be contained within the deployed jar. 为简化起见，我想将html转储到Swing应用程序本地资源（即资源文件夹中）中，该资源将包含在已部署的jar中。 How can I do this? 我怎样才能做到这一点？ Is this even possible? 这有可能吗？

Yes, this possible. 是的，这可能。 This way you have to 这样你必须

Script: inserts the content within the jar file (root folder within the jar) 脚本：将内容插入jar文件（jar中的根文件夹）中
Swing: program has to be (re-)started 摇摆：必须（重新）启动程序
Swing: read file from within jar (eg with getResourceAsStream - method of the class loader) 摆动：从jar中读取文件（例如，使用getResourceAsStream-类加载器的方法）
