Log4j2 JSONLayout给出错误

Question

i am try to config my log4j2 but i always get this errors:

2017-11-06 01:14:15,454 RMI TCP Connection(3)-127.0.0.1 ERROR appender RollingFile has no parameter that matches element PatternLayout
2017-11-06 01:14:15,478 RMI TCP Connection(3)-127.0.0.1 ERROR appender RollingFile has no parameter that matches element PatternLayout
2017-11-06 01:14:15,484 RMI TCP Connection(3)-127.0.0.1 ERROR appender RollingFile has no parameter that matches element JSONLayout

The last error is for "mylevs" appender. Result: i get JSON format logs for warn and error, but for mylevel there is usual data format. What could cause this errors?

My log4j2.xml config:

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

You can define exactly one layout per appender. But you are defining two layouts for each one. Try removing one layout from each of your appenders.
