Config log4j2 with JSON
The log4j2 JSON (or any JSON for that matter) doesn't allow two "AppenderRef" entries to exist, so you should use a config more like the following
{ "configuration":{ "appenders": { "RandomAccessFile": { "name": "FILE", "fileName": "app.log", "PatternLayout": { "pattern": "%d %p %c{1.} [%t] %m%n" } }, "Console": { "name": "STDOUT", "PatternLayout": { "pattern": "%m%n" } } }, "loggers": { "root": { "level": "trace", "AppenderRef": [ { "ref": "STDOUT" }, { "ref": "FILE" } ] } }}}You can also use 'appender-ref' instead of AppenderRef
