Is there way to specify current line number in log4j pattern

Question

I have a pattern to output to console and log file in following format:

[INFO]  17:31:12 - Checking Bla Bla Bla 
[INFO]  17:31:12 - ************* Starting *********************
[INFO]  17:31:12 - Testing Begins

is there any way to append line count so that it looks like:

[001][INFO] 17:31:12 - Checking Bla Bla Bla 
[002][INFO] 17:31:12 - ************* Starting *********************
[003][INFO] 17:31:12 - Testing Begins

Answer 1

In Log4j 1, the symbols can be seen here http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html

Line Number is %L.

In Log4j 2, the symbol is also %L
