Play Framework自定义资源:如何复制到目标? [英] Play Framework custom resources: how to copy to target?

问题描述

我有一个.csv文件，必须在应用程序启动时读取.

I have a .csv file, that must be read on application startup.

如何发挥作用将此文件复制到目标(运行"或启动").

How can I make play to copy this file to target (to "run" or "start" it).

我正在尝试使用Global.class.getResourceAsStream("/file.csv")访问全局类中的该文件，但结果始终为空.

I'm trying to access this file in Global-class with Global.class.getResourceAsStream("/file.csv"), but the result is always null.

好的-谢谢. 我已经用conf/ressources文件夹中的文件管理了它，并使用/ressources/file.csv路径加载了它

OK - thanks. I have managed it with my file in conf/ressources folder and loading it with /ressources/file.csv path

推荐答案

您可以在conf文件夹中创建resources文件夹，将文件放在此处，然后通过调用创建InputStream

You can create a resources folder in your conf folder, put your file there, and then create an InputStream by calling

Play.classloader.getResourceAsStream("resources/file.csv");

请注意，您不应使用/开头路径，因为这样应用程序将无法解析路径并在启动时抛出java.lang.ExceptionInInitializerError: null.

Note that you should not start the path with a /, because then the application will not be able to resolve the path and throw a java.lang.ExceptionInInitializerError: null on startup.
