In order to configure the ColumnMapping type in log4j2 using the properties format, you need to define a property with the name "columnMapping", and set its value to a comma-separated list of key-value pairs in the format "columnNumber=columnName".
Here is an example configuration:
appender.console.type = Console
appender.console.name = Console
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{ISO8601} [%t] %-5p %c{1} - %m%n
appender.console.columnMapping = 1=Date, 2=Thread, 3=Level, 4=LoggerName, 5=Message
In this example, the ColumnMapping type is added to the layout of the console appender. The "columnMapping" property is set to a comma-separated list of key-value pairs, where the key is the index of the column (starting from 1), and the value is the name of the column.
This configuration will result in the console output being formatted with columns for the date, thread name, log level, logger name, and log message.
