如何在 log4j2 中向 appender 添加变量？

Question

is there way to add variables from code to appender? eg <param name="sql" value="INSERT INTO logs(name,log,log_lvl,log_date) VALUES(" + myClass.getUser().getName() +",'%m','%p','%d')"/>

Answer 1

I think you are trying to configure Log4j2 with Java code. Check out Programmatic Configuration . It also covers configuring appenders, which is the level at which you can define the appender's sql parameter if you so wish.
