如何从属性 object 配置 log4j2？

Question

Can log4j2 be initialized from Properties object (no properties file)? This was supported in old log4j 1.2.x (see code below), but I didn't find how to implement this with new log4j2.

Properties props = new Properties();
// ...set some properties
PropertyConfigurator.configure(props);

Did you try looking on the Apache Log4J 2 Documentation website?

There's the GitHub apache / logging-log4j2 where you have a section detailing the Usage with code snippets.

Please, keep in mind the security vulnerabilities issues discovered in Log4j 2. Recommended you upgrade to Log4j 2.3.1 (for Java 6), 2.12.3 (for Java 7), or 2.17.0 (for Java 8 and later). As recommended also in Apache Log4j 2 website. There are also answers on StackOverflow like this one log4j2 -version 2.5 - How to Configure log4j2 using a java.util.properties object
