我正在使用带有Java 11的log4j2(2.11.1)并尝试Logger使用以下命令获取对象:
private static final Logger LOG = LogManager.getLogger();
(从进口log4j-api中org.apache.logging.log4j)
在运行时,我收到以下错误:
WARNING: sun.reflect.Reflection.getCallerClass is not supported. This will impact performance.
Exception in thread "main" java.lang.ExceptionInInitializerError
Caused by: java.lang.UnsupportedOperationException: No class provided, and an appropriate one cannot be found.

org.apache.logging.log4j.LogManager.callerClass(LogManager.java:555)

at org.apache.logging.log4j.LogManager.getLogger(LogManager.java:567)
at app.App.<clinit>(App.java:11)
哪个有意义 - 不支持getCallerClass,因此记录器无法确定类名.
它应该以这种方式工作吗？当然,我不必将类名硬编码到每个记录器中？
