我也是，同求.已经在WEB-INF/lib下引入了log4j-core-2.11.0.jar;依然报错：ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console

Solved the error message by setting the system property for log4j2 configuration file. below is the below code.

System.setProperty("log4j.configurationFile","./path_to_the_log4j2_config_file/log4j2.xml");
Logger log = LogManager.getLogger(LogExample.class.getName());
