Java/Tomcat:ServletContext& getResourceAsStream问题 [英] Java/Tomcat: ServletContext & getResourceAsStream Problems

问题描述

我正在尝试从Tomcat Web应用程序访问conf文件(位于WEB-INF文件夹中).目前，我已将该文件的位置硬编码为String.但是，当tomcat/webapps文件夹与我的硬编码String所指示的位置不同时，这将不起作用.我一直在网上寻找，似乎正在使用getResourceAsStream ()方法，但我很难将其投入使用.调用getServletContext ()方法时，我的应用程序不喜欢它.谁能帮我吗?

I am trying to access a conf file (located in the WEB-INF folder) from a Tomcat web app. At the moment, I have the location of the file hard coded as a String. However, this does not work when the tomcat/webapps folder is in a different location than my hard coded String indicates. I've looked online and it seems like using the getResourceAsStream () method is what I'm looking for, but I'm having a hard time getting it to work. My application is not liking it when I call the getServletContext () method. Can anyone help me?

推荐答案

为解决此问题，我在WEB-INF下创建了两个文件夹(path/to/app/WEB-INF/classes/mypackage/)，然后将文件放入在此文件夹中.然后，从我的POJO中调用this.getClass.getResourceAsStream ("<filename>")打开流.为了仅获取一个字符串，它是文件的完整绝对路径名，我做了this.getClass.getResource ("<filename>").toString ().substring (5).

To solve this problem I created two folders under WEB-INF (path/to/app/WEB-INF/classes/mypackage/) and then put my files in this folder. Then, from my POJO I called this.getClass.getResourceAsStream ("<filename>") to open up a stream. To just get a String that was the complete absolute path name of a file I did this.getClass.getResource ("<filename>").toString ().substring (5).
