将参数传递给log4j文件

问题描述

我听说Java中的.properties文件可以接受字符串参数({0}，{1}，等等...)

I have heard that a .properties file in java can accept String arguments ({0}, {1}, and so on...)

能否请您提供一个示例来说明如何在log4j.properties文件中使用这些类型的参数?

Can you please provide an example to show how to use these kind of arguments in the log4j.properties file?

此外，请帮助提供示例代码，以显示如何在加载文件时将参数传递给文件.

Also, please help with a sample code showing how to pass the argument to the file while loading the file.

推荐答案

在log4j文件中:

log4j.appender.file.File=${log4jjava}

在您的Java代码中(初始化log4j的类):

In your java code(the class that init log4j):

System.setProperty("log4jjava", PATH_YOU_WANT_TO_SET);
//then load your property file
