在log4j附加程序中从WEB-INF文件夹加载属性文件 [英] Loading properties file from WEB-INF folder in a log4j appender

问题描述

我们正在为我们的应用程序编写自定义log4j附加程序。附加程序应将其事件记录到数据库中。现在，我遇到的问题是建立数据库连接。我们的jdbc设置位于一个名为jdbc.properties的文件中，该文件位于WEB-INF文件夹的正下方。

We're writing a custom log4j appender for our application. The appender should log its events to a database. Now the problem I'm having is setting up the database connection. Our jdbc settings are in a file called jdbc.properties which is located directly under the WEB-INF folder.

我尝试使用以下代码访问属性文件

I've tried accessing the properties file using the following code

InputStream stream = Thread.currentThread().getContextClassLoader()
                    .getResourceAsStream("jdbc.properties");

...，但流导致为空。有什么想法可以从log4j附加程序的WEB-INF文件夹中加载属性文件，而无需将属性文件移动到另一个位置？

... but stream results in being null. Any ideas how I can load a properties file from the WEB-INF folder in a log4j appender without moving the properties file to another location?

推荐答案

也许可以尝试，

 String  path =Thread.currentThread().getContextClassLoader().getResource("/").toURI().resolve("../jdbc.properties").getPath();
 Properties ps=new Properties();
 ps.load(new FileInputStream(path));
