将属性文件加载到部署在JBoss中的Java servlet中作为战争 [英] Load properties file in a java servlet deployed in JBoss as a war

问题描述

我在JBoss 4.0.2中部署了一个作为战争的servlet.我有一个已部署的应用程序的属性文件.我应该把这个文件放在哪里?在jboss server \ default \ conf文件夹中的conf目录下?如何以可移植的方式加载该属性文件?

I have a servlet deployed as a war in JBoss 4.0.2. I have a properties file for the deployed application. Where should I put this file? Under the conf directory in the jboss server\default\conf folder? How do I load that properties file in a portable manner?

推荐答案

要以便携式的方式加载该属性文件，最好的方法是将其放在Web应用程序的类路径中(在WEB-INF/lib/或WEB-INF/classes/下的JAR中，或者在应用服务器类路径上，如果您希望能够在不重新包装Web应用程序的情况下编辑该文件)，并使用

To load that properties file in a portable manner, the best way would be to put it on the classpath of the web application (either in a JAR under WEB-INF/lib/ or under WEB-INF/classes/ or on the app server classpath if you want to be able to edit that file without repackaging your web application) and to use Class#getResourceAsStream(String).

以下代码获取属性文件的InputStream，该属性文件与执行代码的servlet位于同一包中.

The following code gets an InputStream for a property file which resides in the same package as the servlet in which the code is executed:

InputStream inStream = Thread.currentThread().getContextClassLoader()
                 .getResourceAsStream("myfile.properties");

然后， Properties 对象(跳过异常处理):

Then, load(InputStream) it into a Properties object (skipping Exception handling):

Properties props = new Properties();
props.load(inStream);
